Recently, the pre-deethanization and pre-hydrogenation catalyst BC-H-22A, independently developed by the Beijing Research Institute of Chemical Technology, was put into use in an ethylene plant abroad. This is the first time that a domestic catalyst of this type has been used on an industrial scale abroad. The results show that this catalyst performs excellently and possesses good stability, marking a successful entry by Beihua Research Institute into the overseas market in the field of selective hydrogenation of acetylene.   In recent years, as the use of lighter feedstocks for ethylene cracking has become more common and the cost advantages of cracking light hydrocarbons have become apparent, the construction of pre-deethanization units in China has continued to advance. Multiple ethylene production facilities have adopted a pre-hydrogenation process prior to pre-deethanization, with catalysts previously relying on imports. Through in-depth research, Beihua Institute developed the unique domestically produced pre-deethanization pre-hydrogenation catalyst BC-H-22A, which was successfully applied in an ethylene production plant using butane cracking in China, providing strong technical support for the successful commissioning of the plant. Next, BEIC will focus on market demands, continuously improve the performance of catalysts and expand their application areas, thereby contributing to the development of ethylene technology.
