Optimization of oil extraction from waste “Date pits” for biodiesel production

Abstract Biodiesel produced from non-edible feedstocks is increasingly attractive alternative to both fossil diesels and renewable fuels derived from food crops. Date pits are one such lipid containing feedstock, and are widely available in Oman as a waste stream. This study analyses the effects of soxhlet process parameters (temperature, solvent to seed ratio and time) on the extraction of oils from waste Date pits and the subsequent production of biodiesel from it. The highest yield of oil extracted from the Date pits was 16.5 wt% obtained at a temperature of 70 °C, solvent to seed ratio of 4:1 and extraction duration of 7 h. Gas Chromatography analysis showed that Date pits oil consisted

Combustion and emissions characterization of terpenes with a view to their biological production in

Abstract In developing future fuels there is an opportunity to make use of advances in many fields of science and engineering to ensure that such fuels are sustainable in both production and utilization. One such advance is the use of synthetic biology to re-engineer photosynthetic micro-organisms such that they are able to produce novel hydrocarbons directly from CO 2. Terpenes are a class of hydrocarbons that can be produced biologically and have potential as liquid transport fuels. This paper presents experimental studies on a compression ignition engine and spark ignition engine in which the combustion and emissions of 12 different terpenes that could potentially be produced by cyanobacte

Biofuels from Microorganisms

Abstract The production of liquid fuels from biological material ('biomass') is gaining increasing interest worldwide. Climate change, rising fuel prices, political instability and depletion of petroleum resources are some of the recent concerns that have sparked this interest into alternatives from fossil fuels. As a result, many different biomass sources are being evaluated as suitable feedstocks for biofuel production, and these range from plant material, to animal waste, to microorganisms such algae and genetically engineered bacteria. Currently, Brazil and the United States, which make bio-ethanol from sugarcane and maize, respectively are the two major players for commercial biofuel pr

Impression on TEDxGUTech: Connect The Dots

TEDxGUtech is the first TEDx event with 'University' licence from TED.com in Oman, themed under “Connect the Dots”, ideas worth spreading starts with a simple thought and by developing that basic form of an idea and connecting it to another idea, innovation and development happens. Speakers Dr.Basel Dayyani Professor in the German University of technology Dr. Basel Dayyani is Silicon Valley and NASA scientist and entrepreneur with over 30 years of innovations. He worked for world class organizations like NASA, IBM, Microsoft, Parametric Technology and Unisys. He is a graduate of University of Colorado at Boulder from the Center of Astrodynamics Research. He is currently a Computer Science pr
