- Current Challenges in Commercially Producing Biofuels from Lignocellulosic Biomass
This book provides an introduction to the basic science and technologies for the conversion of biomass terrestrial and aquatic into chemicals and fuels, as well as an overview of innovations in the field. The entire value chain for converting raw materials into platform molecules and their transformation into final products are presented in detail. Both cellulosic and oleaginous biomass are considered. The book contains contributions by both academic scientists and industrial technologists so that each topic combines state-of-the-art scientific knowledge with innovative technologies relevant to chemical industries.
Biorefineries are facilities that process biomass into fuels, power and value-added chemicals and with the increasing population and depleting petroleum reserves they are fast becoming more important to society. The technology required to process a wide variety of biomass types can be highly complex due to potentially unknown, varying or difficult to breakdown chemical structures within them. One of the prospective routes to a successful biorefinery, that can treat a wide range of biomass and produce products with good selectivity, is the use of nanoparticles as heterogeneous catalysts. The potential of nanoparticles to catalyse and modify chemical processes, thereby influencing both the nature of the products and their distribution is seen as highly promising. In this publication, we aim to give an overview of the use of a range of nano-catalysts and nano-enzymatic supports for greener biorefinery processing.
Biorefinery: From Biomass to Chemicals and Fuels
A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts such as chemicals. Biorefineries can be classified based in four main features: . The aforementioned features are used to classified biorefineries systems according to the following method:. Techno-economic assessment TEA is a methodology to evaluate whether a technology or process is economically attractive. TEA research has been developed to provide information about the performance of the biorefinery concept in diverse production systems as sugarcane mills, biodiesel production, pulp and paper mills, and the treatment of industrial and municipal solids waste. As for biodiesel production, this industry also has the potential to integrate biorefinery systems to convert residual biomasses and wastes into biofuel, heat, electricity and bio-based green products.

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.

Using biological systems to convert biomass into fuels and chemicals is already feasible, but the costs of doing so make the resulting products uncompetitive economically at present with those produced from petroleum. According to Chris Somerville , professor of alternative energy and director of the Energy Biosciences Institute at the University of California in Berkeley, currently, biological conversion processes are done in batch mode, which has a substantial impact on capital costs and throughput. Successfully developing continuous flow processes could have a marked positive effect on the economic competitiveness of biomass-derived fuels and chemicals. Creating such processes, however, will require significant advances in pretreatment and separations technologies, and realizing those advances requires recruiting chemists and chemical engineers to attack these problems.
