Professor Dong Mingdong and Doctor Lin Lin visit Biomass Group and give lectures to Group Members

  2012.12.31, ProfDong Mingdong and Dr. Lin Lin, who come from iNANO, visited Xishuangbanna tropic botanical garden and lectured for biomass group members. In the morning of December 31, ProfDong first introduced a series research works of using scanning probe microscopy and related techniques for analysis structure characteristics and biological effects of macromolecular under nanometer scales. He emphasized the applications of molecular self assembled in the DNA structure changes, applications of atomic force microscopy in biology, study of the macromolecular self assembly using scanning tunneling microscopy, test and analysis of single molecule mechanical spectrum, Filamentous bacteria transport electrons over centimeter distances. Then, Dr. Lin reported preparation of a novel carbon based catalyst and its application in biodiesel production. 继续阅读“Professor Dong Mingdong and Doctor Lin Lin visit Biomass Group and give lectures to Group Members”

Hydrothermal conversion of glycerol: Perspective for high-value chemicals and hydrogen

  At present, due to the rapid development of the global biodiesel industry, the main by-product glycerol is produced abundantly (0.1 Kg of glycerol per 1 Kg of biodiesel production), leading to its market price falling sharply. Therefore, it is imperative to develop new applications of glycerol to value-added chemicals and biofuels. 继续阅读“Hydrothermal conversion of glycerol: Perspective for high-value chemicals and hydrogen”

Hydrolysis of cellulose to glucose with nanocatalyst at low temperature (150℃)

  Biomass resource is very rich. The annual global biomass production is equivalent to 10 times of world energy consumption. Almost all biomass is in the form of lignocellulose that contains about 50% cellulose (e.g., wood, grass and crop-straws). Therefore, how to effectively and economically convert cellulose to sugars is the key for biorefining of biomass to biofuels and chemicals. 继续阅读“Hydrolysis of cellulose to glucose with nanocatalyst at low temperature (150℃)”

Organic Electrolyte Solution: New Pretreatment Method for Enzymatic Saccharification of Microcrystalline Cellulose

  During the bioethanol production, pretreatment, serving as the process to de-crystallization of natural cellulose, is required to benefit the subsequent enzymatic saccharification and to increase the porosity of its surface. 继续阅读“Organic Electrolyte Solution: New Pretreatment Method for Enzymatic Saccharification of Microcrystalline Cellulose”

Producing biodiesel from Jatropha oil by solid acid catalyst

  Recently, biodiesel has gained significant attention as it is a renewable, biodegradable, less pollutant emitting, non-toxic and more environmentally friendly fuel source as compared with the fossil diesel fuel available at present. Biodiesel can be used as a substitute for petrochemical diesel by blending with petrochemical diesel. In the past 10 years, global biodiesel market emerged stabile growth of biodiesel production. The raw materials for biodiesel production account for almost 60~80% of the total biodiesel cost. Therefore, a number of research projects have been carried out using non-edible oils such as Jatropha oil or fats, and other waste oils, to reduce the raw material cost. 继续阅读“Producing biodiesel from Jatropha oil by solid acid catalyst”

Using Jatropha hulls to produce 2,3-butanediol

  Development of bio-refineries has recently attracted increasing attention as a means to provide sustainable alternative solutions to deplete environmental pollution and energy crisis. As more and more Jatropha seeds are used to extract crude oil for biodiesel, a large amount of hulls is generated. How to make full use of these hulls is important for Jatropha biodiesel industry. As Jatrophahulls are rich in carbohydrate (cellulose: 43%; hemicellulose: 15%), further studies are necessary to utilize these polysaccharides to produce sugars for value-added products, such as ethanol, acetic acid, 2,3-butanediol. 2,3-Butanediol is one of the important bio-based chemicals and liquid fuels that exhibits a wide range of potential utilizations in the manufacture of printing inks, perfumes, fumigants, moistening, plasticizers, foods and pharmaceuticals. 继续阅读“Using Jatropha hulls to produce 2,3-butanediol”
