Description

technical field

[0001] The invention relates to a method for preparing furfuryl alcohol by hydrogenating furfural, in particular to a method and a system for preparing furfuryl alcohol by hydrogenating furfural in a liquid phase. Background technique

[0002] Furfuryl alcohol is an important chemical raw material. The furan resin produced by it is widely used in foundry, automobile and other industries. Furfuryl alcohol is also used in medicine, pesticides, coatings and other fields. According to domestic and foreign literature reports, the production process of furfuryl alcohol is classified from raw materials, and mainly contains the following: (1) furfural route; (2) ethanol, aluminum reduction route; (3) sodium borohydride reduction route; Classification: (1) normal pressure or low pressure (0.1-1MPa), (2) medium pressure (1-10MPa), (3) high pressure (>10MPa); classification by furfural phase: (1) liquid phase; (2) ) gas phase.

[0003] At present, furfuryl alcohol ...
