Abstract: A method is provided to transform biomass. Non-food biomass is preprocessed. Then, fermentation is processed to generate ethanol. Ethanol is dehydrated through a catalyst to generate ethylene. After the dehydration, oligomerization is processed with a catalyst to transform ethylene into olefins having 6˜20 carbon atoms (C6˜C20). The olefins are hydrotreated into alkanes. Thus, C6˜C20 hydrocarbons having long carbon chains are formed. The hydrocarbons having 6˜10 carbon atoms can be used as gasoline; those having 8˜16 carbon atoms, jet fuel; and those having 16˜20 carbon atoms, diesel. On generating ethanol, byproducts of lignin may be generated. The byproducts can be processed through depolymerization/deoxygenation to generate aromatic hydrocarbons or can be gasified to generate methanol or dimethyl ether. By further processing dehydration, aromatic hydrocarbons are generated to be mixed into gasoline, jet fuel or diesel. Or, the lignin byproducts are gasified to generate syngas.

Abstract: An oil product of gasoline is fabricated. The product contains hydrocarbon compound ranged as a gasoline composition. The purification process of dimethyl ether (DME) used in the present invention greatly reduces the feed rate for obtaining a smaller reactor with cost down. Carbon dioxide (CO2) is separated to be recycled back to the gasifier to be reused, archived or used otherwise for improves global environment. At the same time, CO2 is reacted with hydrocarbons, water vapor, etc. through a novel high-temperature plasma torch to generate a synthesis gas (syngas) of carbon monoxide (CO) and hydrogen (H2) for regulating a hydrogen/carbon ratio of a biomass- or hydrocarbon-synthesized compound and helping subsequent chemical synthesis reactions. In the end, the final gasoline production has a high yield, a high octane rate, low nitrogen and sulfur pollution and a highly ‘green’ quality.
