A kind of petroleum low-temperature catalytic cracking catalyst and using method

Abstract

The invention discloses a petroleum low-temperature catalytic cracking catalyst and a use method, wherein the catalyst is boric acid. The use method of the catalyst comprises the following steps that A, firstly, heavy oil is put into a heating cracking furnace to be heated to be at the temperature of 100-150 DEG C, and dehydration is performed; B, then the boric acid with the weight of 0.8-1.2% the weight of the heavy oil is added and stirred in a heat preservation mode; C, then the mixture is gradually heated, oil generation starts at the temperature of 180 DEG C, the oil steam evaporation amount is maintained to be uniform and stable, oil products are recycled through fractionation and cooling, the oil products accounting for 60% of the total oil evaporation steam can be recycled at the temperature of 330 DEG C, then the mixture is warmed up to be at the temperature of 400 DEG C, the mixture is stopped from being warmed up, and the mixture is kept warm at the temperature of 400 DEG C until no oil is generated. The petroleum low-temperature catalytic cracking catalyst and the use method have the advantages that the catalytic cracking temperature is low, the efficiency of petroleum low-temperature catalytic cracking is improved, the reaction is accelerated, the production efficiency is improved, and therefore the reaction effect is better.
