Most of the heavy oil from Chinese crudes are good cracking feeds for their low sulphur content and paraffinic characteristics. Crude cracking and atmospheric residue cracking have been studied ever since the end of 1960's.This report reviews the recent research on reducing the coke deposition during residue cracking. By using a new series of zeolite catalyst, raising the riser temperature, lowering the reaction pressure, increasing the steam injection, improving the feed atomization, applying rapid separation and shortening the feed residence time, etc., coke yield has been significantly decreased both at the 0.24 ton/day pilot plant and commercial units. Metals passivation, especially for nickel has also been studied.The operation parameters and the product yields of residue cracking in three refineries are listed. Gasoline plus light cycle oil yields for two atmospheric residues and vacuum bottoms mixed feeds are 70~76%and over 80% in weight, respectively.

The present world refinery capacity is estimated at about 3600 million tons per year. The light oil yield in developed countries is above 65%. The world average percentage of oil used in the production of chemicals is about 7-8%. In 1985 the total world ethylene production was 63.95 million tons. The present development of the world petrochemical industry can be characterized with the following features: (1) Distribution tends to be rationalized and plant size optimized. (2) Utilization of resurces tends to rationalize and processing goes deeper and depper. (3) The petrochemical industry is now on the process of shifting from energy consumming industry to energy saving industry. (4) The catalysis technology is becoming more and more effecient. (5) The pollution of environment is in principle under control. It is estimated that the present drop of oil price will be generate a new impaet on the development of the petrochemical industry.
