ＲＪＷ－１石蜡加氢精制催化剂首次在石蜡加氢工业装置试验成功。本文介绍了匹配使用ＲＪＷ－１石蜡加氢精制催化剂与ＲＧ－１保护剂的工艺及低温湿式预硫化技术。该催化剂在较低的反应温度下，具有高的饱和稠环芳烃的能力和较小的裂解性能。１年多的生产实践表明，在反应温度２４１℃下，能生产出合格的食品级石蜡。说明该剂活性十分稳定。 RJW-1 paraffin hydrotreating catalyst for the first time in a paraffin hydrogenation plant successfully tested. This article describes a process that matches the use of RJW-1 paraffin hydrotreating catalyst with RG-1 protectant and low temperature wet presulfiding technology. The catalyst has a high capacity of saturated polycyclic aromatic hydrocarbons and low cracking performance at lower reaction temperatures. More than one year’s production practice shows that at the reaction temperature of 241 ° C, qualified food-grade paraffin can be produced. This agent shows very stable activity.
