| titleOfInvention | A kind of acid catalyst for reducing acid value of high acid value oil, its preparation method, recovery method and application |
| abstract | The invention discloses an acid catalyst for reducing acid value of high acid value oil, its preparation method, recovery method and application. It comprises: three steps of catalyst preparation, application and recovery; the catalyst is composed of the following components and proportions: amino acid 0.1-8%, acid 0.1-8%, alcohol 40-75%, amino acid ester salt solution 20-50% %, water 0-1.0%; the process provided by the invention is to add a certain amount of acid hydrolyzate to the amino acid after stirring and dissolving, and then under the condition of 50-90 ℃, it is prepared by stream-adding alcohol under reduced pressure; wherein, the amino acid, The weight ratio between the acid hydrolyzate and the alcohol is 1-3:1-3:4-8 respectively; the process conditions are mild and have obvious advantages in terms of oil color, product quality and energy consumption. The catalyst can be separated without water washing, neutralization, alkali refining and other steps, and the catalyst can be reused for many times. |
