Abstract

The invention relates to a method for preparing methanol and ethanol by utilizing dead leaves, which comprises the following steps of: (1) gasifying the dead leaves to obtain a gasification product; (2) adjusting the hydro-carbon ratio in the gasification product to the hydro-carbon ratio which is suitable to synthesize the methanol and the ethanol; and (3) adopting a chemical reaction to synthesize the methanol and the ethanol. Compared with the prior art, the method has a reasonable process and simple operation, fully utilizes a natural product of the nature, prepares the methanol and the ethanol by recovering and refining the dead leaves, can relieve the pressure that the methanol and the ethanol are in great demand on the market, and has the advantages of strong environmental protection, low cost and the like.

Description

technical field [0001] The invention relates to methanol and ethanol, in particular to a method for preparing methanol and ethanol from dead leaves. Background technique [0002] With the increasing development of the economy and the acceleration of the industrialization process, the demand for energy in all walks of life continues to expand. Due to the limitation of energy, the growth of energy supply is limited, and there is a serious situation of shortage of supply. On the one hand, it restricts economic development. On the other hand, On the one hand, energy prices are rising day by day, and production and consumption costs are rising accordingly. Among the various energy sources, methanol and ethanol are the most basic energy sources. Both industrial production and daily life need to consume methanol and ethanol. Therefore, the market supply pressure of methanol and ethanol is particularly huge. [0003] At present, people have begun to study the extraction of methanol...
