沥青、重油和渣油的改质加工方案之一就是催化加氢处理工艺。这项技术最有吸引力的方面在于它具有超过1 0 0 %的液体产物 ;它不太吸引人的方面是与催化剂和氢气消耗成本高有关。采用沸腾床加氢处理 ( H- Oil和 L C- Fin-ing工艺 )通过每天加入新剂和除去废剂来维持催化剂的活性
Asphalt, heavy oil and residue reforming process is one of catalytic hydrogenation process. The most attractive aspect of this technology is that it has more than 100% liquid product; its less attractive aspect is related to the high cost of catalyst and hydrogen consumption. Effluent bed hydrotreating (H-Oil and Lc-Fin-ing processes) is used to maintain the activity of the catalyst by adding a new agent and removing the spent agent daily
