This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass pyrolysis has been practised for centuries in the manufacture of charcoal for industry and leisure. Only in the last two decades, however, has attention focussed on a better understanding of the science and technology, with the resultant benefits of better designed and controlled processes that give high yields of liquid products. These liquids, or 'bio-oil' as it is referred to, can be used in a variety of ways: -combustion to replace conventional fuel oil in boilers, process equipment such as kilns and in gas turbines for power generation; -upgrading by hydrotreating or with zeolites to gasoline, diesel and other hydrocarbon fuels, of chemicals; --extraction and upgrading to fuel additives and chemical specialities. Any charcoal produced can also be utilised to form char- water slurries, analogous to coal-water slurries, or bioi-oil slurries which may be used as liquid fuels in many combustion applications. A group of experts was set up in the EC Energy from Biomass programme to evaluate the status and opportunities for deriving useful liquid products from biomass pyrolysis. This book is a report of their findings and conclusions. It forms an authoritative guide to the wide range of technologies employed in biomass pyrolysis, and product upgrading, utilisation and characterisation. Recommendations and conclusions are included to identify promising areas of research and development that will be of value to researchers, planners and companies throughout the world.

This book was released on 2010-09-10 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is increasing recognition that low-cost, high capacity processes for the conversion of biomass into fuels and chemicals are essential for expanding the utilization of carbon neutral processes, reducing dependency on fossil fuel resources, and increasing rural income. While much attention has focused on the use of biomass to produce ethanol via fermentation, high capacity processes are also required for the production of hydrocarbon fuels and chemicals from lignocellulosic biomass. In this context, this book provides an up-to-date overview of the thermochemical methods available for biomass conversion to liquid fuels and chemicals. In addition to traditional conversion technologies such as fast pyrolysis, new developments are considered, including catalytic routes for the production of liquid fuels from carbohydrates and the use of ionic liquids for lignocellulose utilization. The individual chapters, written by experts in the field, provide an introduction to each topic, as well as describing recent research developments.

Download or read book Advanced Upgrading of Pyrolysis Oil Via Liquid liquid Extraction and Catalytically Upgrading written by Yi Wei and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomass is one of the important renewable energy sources which are used to produce carbon-based liquid fuels through biochemical and thermochemical methods. The bio--oil from the biomass pyrolysis is an intermediate and requires upgrading. Catalyst coking is the most difficult challenge during the upgrading process, and results in low hydrocarbon yield and short catalyst life time. Compared with other methods for reducing catalyst coking such as high temperature baking and co-feeding hydrogen, a new route by liquid--liquid extraction to separate chemical compounds in mixture has been established in this study. First of all, the liquid-liquid extraction process using chloroform solvent on raw pyrolysis oil successfully separated chemical compounds by their properties and polarities with high extracting yield and admirable effect on chemical distribution. The acid, aldehyde and unpyrolyzed sugar can be completely removed from the bio--oil mixture. Secondly, an esterification process over the acid-rich water phase of pyrolysis oil achieved acid conversion over 89% of by completely randomized design with temperature and catalyst loading factors. The esterification process followed the Langmuir--Hinshelwood mechanism and reaction constants were calculated to build a practical esterification model for acid compounds. Additionally, dimethyl acetal was also produced by acetalization on the water phase via acetalization. Products determined by HPLC and GC?MS represented similar Langmuir--Hinshelwood mechanism kinetics to esterification, while moisture and acid content in the feedstock are the main inhibitors for the process. Finally, raw bio--oil and liquid--liquid extracted bio--oil on ZSM--5 catalytic cracking was compared to illustrate our new pathway to solve catalyst coking. Temperature played an important role on increasing gaseous product and hydrocarbon yield as shown by GC--MS and Micro--GC analysis. Less catalyst coke and longer catalyst lives were achieved on liquid--liquid extracted bio--oil than raw bio--oil, indicating significant positive results on reducing catalyst coking. Besides, the new method developed in our study had several advantages over the traditional methods to solve catalyst coking. Neither alumina loss happened, nor high cost hydrogen was required, and other types of bio--oil also can be applied in this system.
