METHOD OF LIQUID-PHASE THERMAL CRACKING AND REACTOR FOR ITS EMBODIMENT Russian patent published in 2000 - IPC

FIELD: oil refining. SUBSTANCE: method includes tangential supply of stock into reactor, its cracking with subsequent special withdrawal of cracking products. In this case, stock is supplied in descending flow and in the course of cracking steam is continuously fed from reactor bottom for turbulization of stock and its withdrawal through cavity of cylindrical device located coaxially to reactor body. Reactor has body with branch pipes for stock admission and withdrawal of cracking products, cylindrical device installed inside body and provided with holes in lower part of its wall. Branch pipe for admission of stock is installed tangentially. Cylindrical device has concave bottom. EFFECT: excluded formation of stall zones in reactor and increased residence time of reaction mass in reactor up to 3-6 min. 2 cl, 2 dwg
