Download Biorefinery : from biomass to chemicals and fuels by Michele Aresta, Angela Dibenedetto, Franck Dumeignil PDF

By Michele Aresta, Angela Dibenedetto, Franck Dumeignil

This booklet presents an creation to the elemental technological know-how and applied sciences for the conversion of biomass (terrestrial and aquatic) into chemical compounds and fuels, in addition to an outline of strategies within the box. the complete price chain for changing uncooked fabrics into platform molecules and their transformation into ultimate items are offered intimately. either cellulosic and oleaginous biomass are thought of. The publication comprises contributions via either educational scientists and commercial technologists in order that every one subject combines cutting-edge clinical wisdom with leading edge applied sciences appropriate to chemical industries. chosen issues contain: Refinery of the longer term: feedstock, procedures, items The terrestrial and aquatic biomass creation and houses Chemical applied sciences and biotechnologies for the conversion of cellulose, hemicellulose, lignine, algae, residual biomass Thermal, catalytic and enzymatic conversion of biomass creation of chemical compounds, polymeric fabrics, fuels (biogas, biodiesel, bioethanol, biohydrogen) coverage points of biomass product chains LCA utilized to the vigorous, financial and environmental evaluate of the creation of fuels from biomass: ethanol, biooil and biodiesel, biogas, biohydrogen

Radionuclide and Metal Sorption on Cement and Concrete

Cementitious fabrics are being general as solidification/stabilisation and barrier fabrics for quite a few chemical and radioactive wastes, basically as a result of their beneficial retention homes for metals, radionuclides and different contaminants. The retention homes outcome from a number of mineral stages in hydrated cement that own a excessive density and variety of reactive websites for the fixation of contaminants via numerous sorption and incorporation reactions.

Principles of Combustion

Rules of Combustion, moment version is a revision of what was once the major booklet on combustion engineering. the recent variation has been revised to incorporate new theoretical effects and size ideas of non-intrusive diagnostic equipment, includes extra fabric on chemical kinetics in the course of ignition; and is increased to supply extra in-depth remedy of sensitivity research and techniques for opting for controlling chemical mechanisms.

Example text

As a very strategic point, it has been decided after extensive analysis that EuroBioRef biorefineries should definitely be chemicals/materials-driven, meaning that the best part of the crops are being used to make high-value chemicals and products and that the residues are being used to produce energy, either consumed on-site or being exported under various forms. This is a rethinking of commonly admitted biorefineries concepts that are strongly biofuels-driven. In the various test fields in Poland, Greece, and Madagascar, lignocellulosic plants (willow, giant reed, miscanthus, switchgrass, cardoon) and oil crops (castor, crambe, safflower, lunaria, jatropha, as well as sunflower and rapeseed for comparison) were grown according to smart rotation strategies, and all of them have already been harvested for feasibility evaluations and, when relevant, for further downstream applications in the biorefinery.
