Abstract
By optimizing the composition of the catalyst support material, using amorphous silica alumina with high mesoporous content as the main support and modified beta molecular sieve with excellent aromatics ring opening selectivity as the acidic component, a hydrocracking catalyst suitable for producing high quality ethylene cracking feedstock at low cost was developed. The catalyst has high selectivity for PAHs cracking, while the alkanes are retained in the diesel fraction, which can achieve the purpose of producing more ethylene cracking feedstocks with low BMCI value under medium and low pressure conditions, and provide strong technical support for refining and chemical transformation.
