Abstract:

In the process of oil exploitation, the addition of chlorine containing oilfield additives led to the chloride content in petroleum products seriously exceeding the standard, which led to a large number of organic chlorides entering the reforming feedstock oil, aggravated the corrosion of equipment and pipelines, caused catalyst poisoning and pipeline blockage, and endangered the normal operation of reforming equipment. At present, the main technologies of reforming oil dechlorination include catalytic hydrogenation dechlorination, extraction dechlorination, nucleophilic substitution dechlorination, adsorption dechlorination, etc. The research progress and existing problems of each technology are discussed, and on this basis, the adsorption dechlorination technology is emphatically introduced. Dechlorination agent is the core technology of adsorption dechlorination process. This article provides a detailed introduction to the research progress of metal oxide, activated carbon, and molecular sieve based adsorption and dechlorination agents, especially the analysis, discussion, and outlook on the modification process of molecular sieve based adsorbents.

Key words: reforming oil, dechlorination technology, oilfield additives, organochlorides, molecular sieve, adsorption removal
