Biorefinery: from biomass to chemicals and fuels

The increase in fossil-fuel demand, due to the increase in world energy consumption, and the limitation of the fossil carbon reservoir are forcing human beings to consider another alternative, biofuel, which is renewable and produced with quasi-zero CO 2. Biorefinery is a new term that is related to two main subjects, value-added bioproducts chemical building blocks, materials , and bioenergy biofuels, power, and heat from biomass, considering sustainability assessment and life cycle.

Research, development, and the integration of innovative technologies are the most important prerequisites for the development of sustainable biorefineries, assessing the technical and economic feasibility of advanced biorefineries. Chapter 1 introduces the concept of the EuroBioRef project, its objectives and methodology in line with reaching its objectives in detail.

By reading chapter 1, the reader will gain a brief overview of the whole project. To improve familiarity with the biorefineries, chapter 2 reviews some practical examples of biorefineries based on vegetable oils, wood, and sugars.

By analyzing their capital cost, the authors convincingly indicate the ways in which more cost-efficient biorefineries can be achieved. While chapter 3 is devoted to terrestrial biomass formation, chapter 4 briefly covers aquatic biomass production.

In both chapters 3 and 4, relevant examples are given and compared theoretically and economically. Another issue is started with chapter 5, which explains the physical and chemical biomass pretreatment processes. At the end of this chapter, the author also summarizes the main advantages and drawbacks of each process, which gives readers a good point of comparison.

Chapters 6, 7, and 8 are related to the conversion of biomass into platform molecules and more added-value molecules. One of the best forms of biomass is lignocellulose, which is generally available as waste biomass, as wood, and as a fast rotation crop.

This polymer consists of lignin, cellulose, and hemicelluloses that should then be depolymerized to building blocks. Conversion of biomass into platform molecules occurs via two main routes. The first route, which is the chemical route, is explained entirely in chapter 6. Chapter 7 covers the biotechnological approach.

Conversion of lignin, the most important component of lignocellulose, is of particular significance. For this reason, the development of parallel processes in its conversion into fuels and chemicals is discussed in chapter 8. Chapter 9 comprehensively explains the process development of bioethanol production from lignocellolosic materials from a metabolic engineering point of view.

Chapter 10 is devoted to the homogeneous catalytic conversion of two biosourced feedstocks: lignocelluloses and vegetable oils. In this chapter, the benefits of homogenous catalysis are highlighted, particularly in the fractionation of the biomass, and a comparison is made and supported by introducing some examples.

In addition, catalytic conversion of terrestrial plant-based oils is presented in chapter Although heterogeneous catalysis conversion of cellulosic biomass is discussed in earlier chapters of this book, selected examples of natural compound conversions into molecules with special applications, along with the use of heterogeneous catalysts in a new water-free approach, are discussed in chapter Chapters 13 and 14 deal with synthesis gas or syngas formation.

Syngas is a stoichiometric mixture of CO and H 2 that is produced by the gasification of carbonaceous compound such as coal, petroleum, biofuels, or biomass. In chapter 13, gasification of biomass is explained in detail, starting from the basics and introducing theoretical factors, such as the process of thermodynamics.

The potential applications of syngas as a chemical feedstock, as a fuel by itself, and as an intermediate for the production of fuels or biofuels, are mentioned in chapter Each application is supported by relevant examples. Once again, the conversion of biomass to fuels and chemicals by thermochemical processes is covered in chapter The biomass thermochemical conversion process consists of gasification, biocarbonization, liquefaction, and thermal decomposition.

Although some of these processes are introduced in former chapters, chapter 15 briefly introduces the first three, reviews the biomass pyrolysis process, and compares their feasibility. Chapter 16 comprehensively covers a case study of economic performance and greenhouse gas emissions. In this case study in northern Sweden, the development of cellulosic ethanol production is summarized in detail. The author supports the content with well-sketched figures. The fundamental study of biogas production is discussed in chapter 17, while methane production technologies are mainly discussed in chapter Chapter 17 also introduces the enzymes used in the production of biogas and the role of catalysts, such as iron and nickel, during anaerobic fermentation.

The conversion process in the absence of oxygen, is explained. The final chapter, chapter 18, is the most applied, since it provides an overview of the topics covered in the book. This chapter starts by studying laboratory-scale biomethane and then goes into deep theoretical knowledge, introducing design criteria and different types of appropriate reactors.

In other words, this chapter offers the reader an applicable example of the scaling up of a biogas plant. This book is an appealing and well-organized book with focus on aspects of biorefinery. It starts from the point of relatively basic knowledge of biomass conversion and then delves into the formation process of biofuels and chemicals from biomass, keeping an eye on the economic side of biorefinery projects. Objective Green Processing and Synthesis is an open access, single-blind peer-reviewed journal that provides up-to-date research both on fundamental as well as applied aspects of innovative green process development and chemical synthesis, giving an appropriate share to industrial views.

The contributions are cutting edge, high-impact, authoritative, and provide both pros and cons of potential technologies. Green Processing and Synthesis provides a platform for scientists and engineers, especially chemists and chemical engineers, but is also open for interdisciplinary research from other areas such as physics, materials science, or catalysis.

Biorefinery: From Biomass to Chemicals and Fuels

Biofuels that are produced from biobased materials are a good alternative to petroleum based fuels. They offer several benefits to society and the environment. Producing second generation biofuels is even more challenging than producing first generation biofuels due the complexity of the biomass and issues related to producing, harvesting, and transporting less dense biomass to centralized biorefineries. In addition to this logistic challenge, other challenges with respect to processing steps in converting biomass to liquid transportation fuel like pretreatment, hydrolysis, microbial fermentation, and fuel separation still exist and are discussed in this review. The possible coproducts that could be produced in the biorefinery and their importance to reduce the processing cost of biofuel are discussed. Other countries in the world have set their own targets to replace petroleum fuel by biofuels. Because of the challenges listed in this review and lack of government policies to create the demand for biofuels, it may take more time for the lignocellulosic biofuels to hit the market place than previously projected.

Metrics details. The implementation of biorefineries based on lignocellulosic materials as an alternative to fossil-based refineries calls for efficient methods for fractionation and recovery of the products. The focus for the biorefinery concept for utilisation of biomass has shifted, from design of more or less energy-driven biorefineries, to much more versatile facilities where chemicals and energy carriers can be produced. The sugar-based biorefinery platform requires pretreatment of lignocellulosic materials, which can be very recalcitrant, to improve further processing through enzymatic hydrolysis, and for other downstream unit operations. This review summarises the development in the field of pretreatment and to some extent, of fractionation of various lignocellulosic materials. The number of publications indicates that biomass pretreatment plays a very important role for the biorefinery concept to be realised in full scale.

Biorefinery: From Biomass to Chemicals and Fuels

DOI : Fossil fuels have fueled the world economy for decades. However, given their limited nature, fluctuating prices and the escalating environmental concerns, there is an urgent need to develop and valorize cheaper, cleaner and sustainable alternative energy sources to curb these challenges. Biomass represents a valid alternative to fossil fuels, especially for fuel and chemical production as it represents the only natural organic renewable resource with vast abundance. A vast array of conversion technologies is used to process biomass from one form to another, to release energy, high-value products or chemical intermediates.

Biomass presents an attractive source for the production of fuels and chemicals, mainly due to the concerns over the depleting fossil fuel, growing awareness of environmental issues associated with fossil fuel consumption, and increasing world energy demand. Biomass resources include agricultural and forest residues, energy crops, livestock residues as well as municipal solid waste. This book covers the most recent advances in biomass processing, biochemical and thermochemical conversion technologies, and thus, serves as a useful reference to agriculture engineers, chemical engineers, biotechnology engineers and engineering students. The contents of the book are divided into three sections: biomass overview and processing, biomass thermochemical and biochemical conversion technologies, and integrated biorefinery processes. Section 1 provides an overview of biomass concepts, supply logistics, and processing technologies. This section begins with a chapter on different biomass sources along with their compositions and properties Chapter 1 , followed by discussions on lignocellulosic feedstock supply logistics Chapter 2 , biomass resources in Canada and U.

Pyrolysis of Biomass for Fuels and Chemicals provides a thorough overview of thermochemical conversion of biomass to fuels and chemicals via the pyrolysis platform. The book covers the principles underlying pyrolysis of biomass from the chemical engineering perspective. It discusses thermal-only pyrolysis, the traditional pyrolysis process under inert atmosphere with no catalyst, and the role of catalytic pyrolysis and tail gas reactive pyrolysis in resolving the instability issues associated with product distribution. Finally, pilot and demonstration scale projects from around the world are examined, and some immediate applications of pyrolysis oils in combustion systems are analyzed. Engineering researchers and professionals in the bioenergy, biochemical, and petrochemical fields find in this book a complete resource for understanding the relationships between possible technologies, applications, costs, and products value, as they tackle the challenges for large scale adoption of pyrolysis for the production of 2nd generation biofuels and biochemicals.
