A simple model and results for the decomposition of pulverized cellulosic biomass within a non-oxidizing gas of transient temperature and pressure is presented. This model is used to predict the performance of a novel thermo-chemical biomass conversion scheme termed the reciprocating biomass conversion reactor (RBCR). Calculations indicate that complete thermo-chemical conversion can be complet...

Catalytic pyrolysis is a promising thermochemical conversion route for lignocellulosic biomass that produces chemicals and fuels compatible with current, petrochemical infrastructure. Catalytic modifications to pyrolysis bio-oils are geared towards the elimination and substitution of oxygen and oxygen-containing functionalities in addition to increasing the hydrogen to carbon ratio of the final...

Traditionally, polymers and macromolecular components used in the foam industry are mostly derived from petroleum. The current transition to a bio-economy creates demand for the use of more renewable feedstocks. Soybean oil is a vegetable oil, composed mainly of triglycerides, that is suitable material for foam production. In this study, acrylated epoxidized soybean oil and variable amounts of ...

Vegetable oils are renewable in nature and can be directly used as fuels in diesel engines. However, their high viscosity and poor volatility lead to reduced thermal efficiency and increased hydrocarbon, carbon monoxide and smoke emissions. Transesterification is one of the methods by which viscosity could be drastically reduced and the fuel could be adopted for use in diesel engine. This Ester...

The current study explores co-pyrolysis of sugarcane bagasse, and thermocol waste in a semi-batch reactor to evaluate the influence temperature, blending ratio on yield products, reaction time, thereby characterize maximum liquid product. properties product (bio-oil), solid (bio-char) obtained from thermal bagasse: bio-oil were investigated for physicochemical characterizations. compositional a...

Oil palm shell (OPS) is biomass with high carbon and hydrogen content, so it has the potential to produce renewable energy through thermochemical method. Pyrolysis a relatively inexpensive method that continuously converts into valuable gas, bio-oil, char products. Bio-oil used directly fuel boilers furnaces or oil. This article reviews pyrolysis process of from oil shells, discussing operating...

This paper reports on continuing research at Coventry University into the improvement of highway water quality following flow through a permeable pavement. Such pavements have been shown elsewhere to be efficient in-situ bio-reactors, capable of degrading large quantities of clean motor oil. Further laboratory research, reported here, demonstrates that a commercially obtained oil degrading, mic...

Energy conservation is important for most of the developing countries, including rest of the world. The rapid depletion in world petroleum reserves and uncertainty in petroleum supply due to political and economical reasons, as well as the sharp escalations in the petroleum prices have stimulated the search for alternatives to petroleum fuels. The situation is very grave in developing countries...

Rhamnolipids mainly are produced by Pseudomonas aeruginosa and another microorganism that have been found to have good surface activity. Rhamnolipids are used in various application areas, including environmental, health, food, cosmetic, oil industries, pharmaceuticals and environmental bio remediation particularly in enhanced oil recovery (EOR) and cleaning of oil spills. Many kinds of bio sur...

Biomass derived fuels are preferred as alternative fuels for IC engine due to its abundant availability and renewable nature. In the present work, the complete replacement of diesel fuel with bio-fuels is studied, where the bio-fuels, namely, methyl ester of palm kernel oil and eucalyptus oil were chosen and used as fuel in the form of blends. Various proportions of palm kernel oil and eucalypt...
