摘要

利用提升管催化裂解实验装置研究了加拿大合成原油瓦斯油HGO和LGO的催化裂解反应规律和裂解产品性质。发现总低碳烯烃（乙烯、丙烯和丁烯）产率随反应温度和剂油比的增大存在最大值，随反应时间的延长而减小，随水油比的增大而升高。实验确定了HGO催化裂解的优化反应条件：反应温度620～640℃、剂油比16、反应时间2 s、水油比0.5左右。在此反应条件下，乙烯、丙烯和总低碳烯烃产率分别可达9.0%（质量），15.8%（质量）和32.6%（质量）。催化裂解汽油馏分、柴油馏分和重油馏分含有大量的芳香烃，其中催化裂解汽油馏分总芳香烃含量在80%（质量）以上，主要是甲苯和C8芳香烃;催化裂解柴油馏分总芳香烃含量在60%（质量）以上，主要是单环和双环芳香烃;催化裂解重油馏分总芳香烃含量在70%（质量）以上，主要是多环芳香烃。

Abstract

Reaction performance and product properties of catalytic pyrolysis of HGO (heavy gas oil) and LGO (light gas oil) derived from Canadian synthetic crude oil were investigated in a riser unit.The yield of total light olefins (ethylene

propylene

and butylene) showed a maximum with increasing reaction temperature and catalyst-to-oil mass ratio

decreased with increasing reaction time

and enhanced with increasing steam-to-oil mass ratio.The optimal reaction temperature

catalyst-to-oil mass ratio

reaction time and steam-to-oil mass ratio of catalytic pyrolysis of HGO were 620—640℃

2 s and 0.5

respectively.Under these optimal reaction conditions

the yields of ethylene

propylene and total light olefins reached 9.0%（mass）

15.8%（mass） and 32.6%（mass）

respectively.There were large amounts of aromatics in pyrolysis gasoline

diesel and heavy oil fractions.Gasoline fraction contained above 80%（mass） of aromatics which were mainly toluene and C8 aromatics.Diesel fraction contained above 60%（mass） of aromatics which were mainly single-ring and double-ring aromatics.Heavy oil fraction contained above 70%（mass） of aromatics which were mainly multi-ring aromatics.
