用FV-10催化剂高压加氢制取优质凡士林

Preparation of quality vaseline by high-pressure hydrorefining with FV-10 catalyst

介绍采用中国石油化工股份有限公司抚顺石油化工研究院研制的FV-10石蜡加氢催化剂进行高压一段串联加氢精制制取优质凡士林的试验情况。结果表明,在试验条件下,采用具有代表性的用于工业生产医药白凡士林的原料以及选择适宜的工艺条件,加氢精制产品质量分别符合医药白凡士林的GB 1790—2003国家标准、化妆用凡士林的SH 0008—1990行业标准和食品级凡士林的SH/T 0767—2005行业标准。其中医药白凡士林加氢精制可在比较缓和的工艺条件下操作,一反温度较一般工业生产装置低20℃;化妆用凡士林加氢精制可以选择与医药白凡士林加氢精制相同的操作条件,加氢精制产品各项质量指标均符合化妆用凡士林产品标准要求;食品级凡士林加氢精制需要选择适宜的操作条件,一反温度过低,加氢精制产品的易碳化物含量不合格;一反温度过高,加氢精制产品中含有的碳数少于18的轻组分不合格。

The test of preparing quality vaseline by the single-stage in series process of high-pressure hydrorefining with FV-10 catalyst is described.The results show that under the experimental conditions and by the application of representative materials for commercial production of medicine white vaseline and the selection of the optimum process conditions,the hydrorefining product quality meet the specifications of medicine white vaseline in the national standard GB 1790—2003,specifications of cosmetic vaseline in industry standard SH 0008—1990 and specifications of food grade vaseline in industry standard SH/T 0767—2005.The hydrorefining with FV-10 catalyst can produce medicine white vaseline at relatively mild operating conditions.The medicine white vaseline hydrorefining temperature of the first reactor is 20 ℃ lower than the normal industrial production.The cosmetic vaseline hydrorefining can select the same operating conditions as medicine white vaseline hydrorefining,and the hydrorefining product quality is in line with the cosmetic vaseline industry standard.The food grade vaseline hydrorefining requires the appropriate selection of process conditions.When the temperature of the first reactor temperature is too low,carbonizable substances in the refined products will be off specifications.When the first reactor temperature is too high,the light component with carbon number lower than 18 will fail to meet the specifications.
