The hydrodeoxygenation of a model compound of lignin-derived bio-oil, guaiacol, which can be obtained from the pyrolysis of biomass to bio-oil, has attracted considerable research attention because of its huge potential as a substitute for conventional fuels. In this study, platinum-loaded HY zeolites (Pt/HY) with different Si/Al molar ratios were used as catalysts for the hydrodeoxygenation of...

Rubber seed oil (RSO) and its sodium soap were pyrolysed in a batch reactor to obtain low molar mass organic substances. The pyrolitic oil of RSO was redistilled and the distillates were characterized by GC-MS and FTIR. Density, acid value, saponification value and ester values were also measured according to the ASTM standard methods. A similar analysis was done for samples taken out at differ...

Bio-oil produced from fast pyrolysis of biomass has been investigated as a renewable fuel and as a source of industrial chemicals. The lignin fraction of bio-oil produced from wood in our fast pyrolysis reactor was separated by using only water and methanol with a 25% yield based on bio-oil weight. This separation procedure appears to be of lower cost than the reported extraction procedure usin...

The substantial increase in oil prices over the past few years has been reflected in asphalt prices. Moreover, the maximization of fuel production in refineries has reduced asphalt supply. These conditions have prompted the development of alternative sources of asphalt binders, including bio-oils derived from the fractionated fast pyrolysis of biomass that comes from agricultural and forestry r...

Lignocellulosic biomass conversion to produce biofuels has received significant attention because of the quest for a replacement for fossil fuels. Among the various thermochemical and biochemical routes, fast pyrolysis followed by catalytic hydrotreating is considered to be a promising near-term opportunity. This paper reports on experimental methods used 1) at the National Renewable Energy Lab...

Especially, India has deficient amount of fossil fuel .for this reason, India has to...

Pyrolysis is a relatively simple, inexpensive, and robust thermochemical technology for transforming biomass into bio-oil, biochar, and syngas. The robust nature of the pyrolysis technology, which allows considerable fl exibility in both the type and quality of the biomass feedstock, combined with a distributed network of small pyrolysis plants, would be compatible with existing agriculture and...

Worldwide energy crisis forced the researchers to explore for new and alternate sources of energy. For the developing countries this problems are acute. Generation of any kind of waste is a problem to the environment. Some wastes have the characteristics of producing energy by different thermochemical conversion. In the present work, waste tires were pyrolysed in a fixed bed reactor. The influe...
