    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.
