一、引言 自1956年美国建成世界上第一座以重油为原料的部分氧化法工业装置以来,近40年中重油制气工艺已趋近于完整成熟。在日产5万m~3的裂解炉上以重油为原料制气,这种生产方法我们已经应用了多年,从整体上看,重油催化裂解制气具有投资省上马快,生产灵活机动,产气热值较大等诸多优点, I. INTRODUCTION Since 1956, when the United States built the world’s first partial oxidation process industrial plant using heavy oil as raw material, the process of producing medium-heavy crude oil in the past 40 years has approached complete maturity. In the Nissan 50,000 m~3 cracking furnace, heavy oil is used as raw material for gas production. This production method has been used for many years. On the whole, the heavy oil catalytic cracking gas production has the advantages of quick investment, flexible production, and gas production. There are many advantages such as greater calorific value,
