Abstract

Alcohol fuel can be produced by: treating raw materials, fermenting, refining, molecular sieve adsorption dewatering, and waste liquid treating. A thermal coupling is used to connect dewatering and condense distilling procedures, i.e., gas alcohol from refining process is fed to molecular adsorption dewatering process after thermal coupling condensation and distillation. Heat energy released from cold condensation is used as heat energy for distillation. None of energy is needed any more. The raw materials may be corn, rice, wheat, Chenese sorghum, dry sweet potato, cassawa, sugarcane juice, sugarbeet juice, or green cyrup, etc.

Description

technical field

[0001] The present invention relates to a method for producing fuel ethanol from starchy or sugary raw materials. Background technique

[0002] In the 20th century, petroleum was used as the main energy source and the raw material of petrochemicals. However, there have been two serious problems: one is that oil is a non-renewable resource, and it is exhausted due to excessive exploitation and consumption; the other is that the use of oil as fuel and chemical raw materials has caused serious environmental damage. especially CO 2 the greenhouse effect. Based on the above two reasons, people are working hard to develop new renewable energy sources and clean fuels that will not pollute the environment.

[0003] Fuel ethanol produced from starchy or sugary raw materials has a combustion performance similar to that of fossil fuels, and its production raw materials are biological sources, which is a renewable energy source. In add...
