METHOD OF CATALYTIC CRACKING OF HYDROCARBON RAW MATERIAL AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC C10G11/18 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil refining of hydrocarbon raw material and can be used for increasing the production of motor fuels. Invention refers to method of catalytic cracking of hydrocarbon raw material on fine catalyst with production of end products. Method involves contacting of raw material and regenerated catalyst in once-through reactor, separation of vaporous products from waste catalyst in cyclone separators of the first stage, which are directly connected to the outlet of once-through reactor, supply of waste catalyst to steaming zone via dust return stand pipe of cyclone separators of the first stage, which is submerged into fluidised catalyst bed, and separation of entrapped hydrocarbons from it by water vapour treatment with output of formed gases to separation zone, supply of vaporous products directly to receiving zones and mixing in them with gases supplied from separation zone via annular channel between receiving chamber and gas outlet branch pipe of cyclone separators of the first stage, final cleaning of flow of vaporous products and gases in cyclone separators of the second stage, which are connected to receiving zones; at that, residence time of vaporous products in each receiving zone is 0.10-0.35 s, flow of vaporous products and gases is removed from each receiving zone at an angle of 50-90° to direction of its supply to receiving zone. Also, the invention refers to the device for performing catalytic cracking of hydrocarbon raw materials.

EFFECT: increasing the output and quality of end products.
