Biofuels production from hydrotreating of vegetable oil using supported noble metals, and transition metal carbide and nitride
<p>The focus of this research is to prepare non-sulfided hydrotreating catalysts, supported noble metal and transition metal carbide/ nitride, and evaluate their hydrocracking activities and selectivities by using soybean oil as the feedstock. For comparison study, catalytic cracking of soybean oil …

Evaluation of the Brazilian potential for producing aviation biofuels through consolidated routes
… and a vast experience in biomass utilization for biofuels production. In this sense, this dissertation presents a case study for assessing the potential of biojet fuel production in Brazil. To this end, some indicators as feedstock availability, environmental performance and the costeffectiveness …

Bioflocculation of Wastewater Treatment Pond Suspended Solids
… or too energy intensive for application in algae biofuels production. This research investigates using a small amount of activated sludge material to promote bioflocculation of algae in pond effluent. It was hoped that the findings may demonstrate a path for municipalities to keep their lagoons, …

Using Resident Small Mammals to Assess the Habitat Potential of Experimental Biofuels Feedstocks
Biofuels are predicted to become an increasingly important part of the global energy economy. The use of native grasses for production of cellulosic ethanol is an emerging area of research. However, there is a paucity of research related to the expanded use of biofuels in the northern Great Plains. …

Genetic and phylogenetic characterization of microalgae strains in view of their exploitation for CO2 capture and biofuel production
… In fact, differently from the first generation biofuels, the use of microalgae to produce bioenergy does not involve the triggering of "food for fuel" competitivity and thus represents a sustainable mean to face significant concerns, such as wars and political instabilities deriving from oil …
