The Amelioration And Optimization Riser Reactor System In The Process Of Catalyse And Cracking Technics

The quality of gasoline was required rigorous for environmental protectting purpose, but the content of olefin and the value of octane can not meet the requirement of gasoline standard, thereby reducing olefin content and improving octane value were the urgent affairs for oil refining technics. The technics of catalyse and cracking took up the main place in the oil refining technics in China. 85% of commercial gasoline came from the technics.of catalyse and cracking, and the content of olefin achieved 45%～ 60% in the gasoline. While the capability of adding hydrogen was short of and the materials of catalyse reforming were insufficiency, so it is practical significance and economical purchase to ameliorate and optimize existing technics and exploiture new technics .The primary work in the article was followed.The amelioration riser reactor systemChanging the riser reactorIn order to increase production of lique facient petroleum gas and propylene the catalyst, long reaction time, large proportion of solvent and oil, and high reacting temperature were integrant in order to attain reacting depth.The equipment of expeditiousness separation was altered, so the oil gas and catalyse were separated rapidly, and the over-cracking reaction was lessen.The rivet gridiron of alloy steel was set in the first regeneration container.The steam over-heat platepipe was added in the second regeneration containerThe reacting oil gas had phenomenon of condensation low temprture conditions, and adhesived on the surface of catalyse and sedimentation...
