METHOD OF PROCESSING ALIPHATIC C - C-HYDROCARBONS INTO PRODUCTS ENRICHED BY AROMATIC HYDROCARBONS Russian patent published in 1999 - IPC

FIELD: petroleum processing and petrochemical processes. SUBSTANCE: method consists in providing reaction zones in the form of tubular reactors filled with catalyst containing Pentasil-group zeolite placed in combustion space of active furnace for bringing outside surfaces if reactors into direct contact with furnace gases and thereby providing isothermal conditions for catalytic conversion of raw material. Each tubular reactor is connected to raw material collector over pipeline whose hydraulic resistance is 1.5-3-fold superior to that of catalyst-filled reactor. Raw material is preheated by heat exchange with leaving product stream and passed through reaction zone at 380 to 600 C, pressure 0.2 to 3 MPa, and volume velocity 0.5 to 6 hr^-1. Product is then subjected to task-oriented fractionation. EFFECT: increased catalyst and reactor space utilization efficiency. 1 dwg, 6 ex
