In order to improve enzymatic hydrolysis efficiency, several approaches including liquid hot water (LHW) pretreatment, adding surfactant, magnetic stirring and fed-batch hydrolysis were investigated, in which Sweet sorghum bagasse (SSB) was chosen as the feedstock. The experiment results showed...

Inhibitory effects of lignocellulosic degradation compounds from hydrolysate on microbial oil production. Jijiao Zeng, Xiaochen Yu, Yubin Zheng, Shulin Chen* Department of Biological Systems Engineering, Washington State University, Pullman, Washington 99164-6120, USA *Corresponding author. Tel: +1...

The Carboxylate Platform, also known as the MixAlco TM process, is an acidogenic fermentation process using mixed culture inoculums, which offers several advantages compared to conventional bioprocessing, such as: non-sterile fermentation, the use of inexpensive tanks, adaptability to a wide...

Catalytic conversion of bio-oil vapor has attracted considerable interest as a promising pathway for upgrading. In this work, the reaction of anisole and guaiacol, phenolic model compounds commonly existing in bio-oils, were studied over an acidic silica-alumina catalyst and at varying space times...

The objective of this work is to use thermal pretreatment to separate the complex bio-oil mixture to produce less complex vapor streams of products from 1. light oxygenates (small aldehydes, acids) , 2. furan derivatives, and 3. phenolics. The selective production of products by thermal treatment...

Some processes aimed to biofuels production, use lignocellulosic wastes as feedstocks for fermentative conversion. If this is the case, pretreatment is required to make these resources fully digestible. Among a wide range of pretreatment options, this study focuses and compares oxidative-alkaline...

Study on the Pyrolysis Characteristics of Biomass Compositions in Medical Wastes DENG Na * , Wang Weiwei, ZHANG Yu-feng, MA Hong-ting （School of Environmental Science & Engineering, Tianjin Uninversity, Tianjin 300072, China) Abstract: To obtain pyrolysis characteristics of biomass compositions...

A major challenge in developing biorefinery is that the availability of biomass often limits the scale of the plant thus the feasibility of an operation. We proposed an integrated lipid-based platform as one technical option. According to this concept, different biomass resources will be first...

Research within the Great Lakes Bioenergy Research Center aims to better understand the bottlenecks associated with bioconversion of lignocellulose to liquid transportation fuels, knowledge which will then be used to improve the efficiency of this process. Much of these studies are currently...
