众所周知,当前炼油技术方面很重要的一个环节即是催化裂化设备工艺。我国在这个领域通过长年来不断地努力,催化剂的制备技术得到了很大的进步,国内自产催化剂在某些方面达到甚至一定程度上超过国外水平,比如在渣油裂化能力和抗金属污染等方面取得的成就。但同时,国内在有些方面的技术上仍存在很大的不足。 As we all know, the current refining technology is a very important part of the catalytic cracking process equipment. Through years of continuous efforts in our country, our country has made great progress in catalyst preparation technology. Domestic self-produced catalysts have met or even exceeded some foreign standards in some aspects. For example, in terms of residue cracking capacity and resistance to metal pollution Achievements made. However, at the same time, there are still some major technical shortcomings in some areas in China.
