Phillips石油公司开发出一种脱除汽油中硫的吸附工艺 ,以适应美国和加拿大即将实行的新规则中的 30 ppm指标。与传统的加氢处理工艺相比 ,该工艺操作中正辛烷的损失更小。由流化催化裂化来的汽油通过装有吸附剂的沸腾床 ,吸附剂是锌和其它金属负载于专利的载体上。吸附反应压力 Phillips Petroleum has developed an adsorption process that removes sulfur from gasoline to meet the 30 ppm target in the forthcoming new rules in the United States and Canada. Compared with the traditional hydrotreating process, the loss of n-octane in the process is smaller. Gasoline from fluid catalytic cracking is passed through an ebullating bed containing adsorbent, the adsorbent being zinc and other metals supported on a patented carrier. Adsorption reaction pressure
