DESIGN AND SYNTHESIS OF CARBON SOLID ACID FROM BROWN GREASE SOLID RESIDUE AND ITS APPLICATION ON BIOMASS TRANSFORMATION

摘要

As traditional fossil fuel is not renewable and the exhaustion ofnfossil fuel is foreseen in the next several decades, finding alternativenfuels have become increasingly attractive. Biodiesel, whichnconsisting of fatty acid methyl ester, is renewable, biodegradable,nnon-toxic while it produces less sulfur dioxide and unburned gasesnthan fossil fuel. Great effort has been devoted to produce biodieselnrecently. Generally, Biodiesel is produced from edible vegetable andnanimal oils, which raise the pricing problem and crucial sustainabilitynissues. The bottleneck are known as the cost related to the limitednavailable of fat or oil resources and the catalyst chose [1]. In a broadnsense, the edible vegetable oils are extracted from the crops. And thenincreased demand for these crops will heighten their price in foodnmarket, place additional requirements on the often strainednagriculture system and impose a negative environment impactnthrough the additional energy requirements and eutrophication whichncaused by intensive agricultural processes [2].
