Book Synopsis Advanced Upgrading of Pyrolysis Oil Via Liquid-liquid Extraction and Catalytically Upgrading by : Yi Wei
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.
Book Synopsis Catalytic Microwave Pyrolysis of Biomass for Renewable Phenols and Fuels by : Quan Bu
Download or read book Catalytic Microwave Pyrolysis of Biomass for Renewable Phenols and Fuels written by Quan Bu and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bio-oil is an unstable intermediate and needs to be upgraded before its use. This study focused on improving the selectivity of bio-oilby catalytic pyrolysis of biomass using activated carbon (AC) catalysts. Firstly, the effects of process conditions on product quality and product yield were investigated by catalytic microwave pyrolysis of biomass using AC as a catalyst. The optimized reaction condition for bio-oil and volatile was determined. Chemical composition analysis by GC/MS showed that phenols rich bio-oils were obtained. Furthermore, the effects of different carbon sources based AC catalysts on products yield and chemical composition selectivity of obtained bio-oils were investigated during microwave pyrolysis of Douglas fir pellet. The catalysts recycling test of the selected catalysts indicated that the AC catalysts can be used for 3-4 times with high concentration of phenolic compounds. The individual surface polar/acidic oxygen functional groups analysis suggested the changes of functional groups in ACs explained the reaction mechanism of this process. In addition, the potential for production of renewable phenols and fuels by catalytic pyrolysis of biomass using lignin as a model compound was explored. The main chemical compounds of the obtained bio-oils were phenols, guaiacols, hydrocarbons and esters. The thermal decomposition behaviors of lignin and kinetics study were investigated by TGA. The change of functional groups of AC catalyst indicated the bio-oil reduction was related to the reaction mechanism of this process. Finally, the effects of Fe-modified AC catalyst on bio-oil upgrading and kintic study of biomass pyrolysis were investigated. The catalytic pyrolysis of biomass using the Fe-modified AC catalyst may promote the occurrence of the fragmentation of cellulose, rather than repolymerization as in the non-catalytic pyrolysis which leads to partial of guaiacols derived from furans. Results showed that the main chemical compounds of bio-oils were furans, phenols, guaiacols, and ketones/ethers. The activation energy of Douglas fir by microwave pyrolysis was remarkable lower than by conventional pyrolysis using TGA. And the reaction mechanism of this process was analyzed.

Book excerpt: The trade of global bioenergy commodities, such as ethanol, biodiesel and wood pellets has been growing exponentially in the past decade, and have by 2013 reached true “commodity” volumes, i.e. tens of millions of tonnes traded each year, and billions (both in US$/€) of annual turnover. IEA Bioenergy Task 40 was founded in 2004 and is now in its 4th triennium. For the past 9 years, task 40 has monitored the developments in international bioenergy trade, including the organization of about 20 workshops on trade-related topics, and the publication of over 100 studies, country reports, newsletters, etc. The amount of material produced over the years and insights gained in how biomass markets and international trade of biomass and biofuels has developed is impressive. Besides that the group has produced overviews and insights, also a large amount of practical experience has been brought together in what works and what doesn’t. Last but not least, based on all this, there are clear(er) views on how to proceed to build working sustainable international biomass markets in the future. This book compiles those lessons and insights into an easily accessible book publication.

Available in PDF, EPUB and Kindle. Book excerpt: Fast pyrolysis and related catalytic pyrolysis are of increasing interest as pathways to advanced biofuels that closely mimic traditional petroleum products. Research has moved from empirical investigations to more fundamental studies of pyrolysis mechanisms. Theories on the chemical and physical pathways from plant polymers to pyrolysis products have proliferated as a result. This book brings together the latest developments in pyrolysis science and technology. It examines, reviews and challenges the unresolved and sometimes controversial questions about pyrolysis, helping advance the understanding of this important technology and stimulating discussion on the various competing theories of thermal deconstruction of plant polymers. Beginning with an introduction to the biomass-to-biofuels process via fast pyrolysis and catalytic pyrolysis, chapters address prominent questions such as whether free radicals or concerted reactions dominate deconstruction reactions. Finally, the book concludes with an economic analysis of fast pyrolysis versus catalytic pyrolysis. This book will be of interest to advanced students and researchers interested in the science behind renewable fuel technology, and particularly the thermochemical processing of biomass.
