Problems solved by technology

In the organic waste alcohol liquid produced by the production of 1,4-butanediol, the content of recyclable alcohol chemical raw materials is as high as 50%, and most of the current treatment methods are incineration, which not only wastes the recyclable Organic products pollute the atmosphere and cause waste of resources. It takes about 200-500 yuan to process one ton of waste alcohol liquid
At present, there is no relatively advanced technology for the treatment of this kind of organic waste alcohol liquid water in the world, and many organic components are difficult to decompose
There is no process for decomposing toxic components in alcohol-containing waste liquid in China or even in the world

Abstract

The invention relates to a method for preparing n-butyl alcohol by utilizing an alcohol-containing waste liquid. On the basis of the principle that a hydrogenation reaction can be carried out on unsaturated organic compounds in presence of catalysts to generate saturated hydrocarbon or derivatives thereof, and selective hydrogenation is carried out on toxic low-carbon linear chain unsaturated alcohol and / or unsaturated aldehyde in the alcohol-containing waste liquid by the catalysts, so as to generate desired product-n-butyl alcohol. In the whole method, the procedure is simple, the conditionis easy to control, the product yield is high, the butyl alcohol products have high purity, the equipment investment is low, the production cost is low, the energy consumption is saved, the method ishopeful to be applied to the recovery processing of the alcohol-containing waste liquid in the production process such as butanediol production process and the like, the production additional value is improved, and the environment pollution is reduced, therefore, the method has very important economic significance and social significance.

Description

Technical field [0001] The present invention involves a method of preparing orthopatol with alcohol -containing waste liquid. Background technique [0002] The method of synthesizing positive butanol in traditional industries is mainly based on natural gas and metal nickel as a catalyst.The natural gas and water vapor are transformed directly. 2 The sub -reaction such as carbonization must be increased. The post -processing process must be added. After the processing, it needs to be transformed and de -carbon and nitrogen removal treatment.The production process is complicated, the operating conditions are harsh, the energy consumption is high, the product revenue is low, the three waste treatment is difficult, the equipment cost is high, and the cost is high. [0003] During the production of 1,4-butanol (BDO), a large amount of higher concentration of organic waste liquid will be generated, which contains buoh (butanol), water, and other alcohols such as methanol, propylene, pr...
