摘要
基于国内炼油厂由传统炼油向化工转型的技术需求,中国石油石油化工研究院开发催化裂解多产低碳烯烃CTP技术,并针对大庆宏伟庆化石油化工有限公司500 kt·a-1重油催化裂解装置增产低碳烯烃的技术需求,开发CTP技术专用催化剂LPS-67D.LPS-67D催化剂在该催化裂解装置上的工业应用结果表明,在催化原料和工艺条件相近的条件下,LPS-67D催化剂展现出优异的催化裂解增产低碳烯烃反应性能.与对比催化剂相比,LPS-67D催化剂在确保装置稳定和产品分布相当的前提下,实现丙烯(对重油)收率提高1.57个百分点,液态烃收率提高2.23个百分点,柴油收率降低2.52个百分点,总液体收率提高0.99个百分点,完成了催化剂的使用目标.
Abstract
Based on transforming from producing refined oil products to producing chemical materials of oil refineries in China,PetroChina Petrochemical Research Institute developed the CTP technology for increasing low-carbon olefins production through catalytic cracking process.And LPS-67D catalyst for CTP technology was developed to satisfy the technical needs of increasing the yield of low-carbon olefins at the 500 kt·a-1 heavy oil catalytic cracking unit of Daqing Hongwei Qinghua.The industrial application results of LPS-67D catalyst in this catalytic cracking unit demonstrated that under the similar catalytic raw materials and process conditions excellent catalytic cracking performance for stimulating low-carbon olefins production was achieved by using LPS-67D catalyst.And compared with the contrasted catalyst,in case of the premise of ensuring the stability of the device and the similar product distribution,the propylene(based on heavy oil)yield increased by 1.57 percentage points;the liquefied petroleum gas yield increased by 2.23 percentage points;the diesel oil yield decreased by 2.52 percentage points and the total liquid yield increased by 0.99 percentage points.These results indicate that LPS-67D catalyst reaches the target of application.
