| titleOfInvention | Method for increasing yield of liquid hydrocarbon product |
| abstract | FIELD: gasoline production.SUBSTANCE: invention relates to a method for increasing the yield of a liquid hydrocarbon product and/or the selective formation of С5+hydrocarbons in a method for producing gasoline, in which three streams are used as raw material, the first of which comprises a hydrocarbon fraction representing gasoline fraction with an end-boiling point of no more than 215°C, a second stream includes oxygenate, which is at least one component selected from the group: methanol, ethanol, dimethyl ether, the third stream includes the olefin-containing fraction. The olefin-containing fraction comprises one or more olefins selected from a group comprising ethylene, propylene, normal butylene, isobutylene, in a total quantity of 10 to 50 wt.%. In this method, three reaction zones are used, filled with a zeolite catalyst, which comprises a zeolite of type ZSM-5. The first flow is fed into at least one reaction zone, the second flow is distributed into three reaction zones, the third flow is distributed into three reaction zones. The product flow from the first reaction zone is fed into the second reaction zone, and the product flow from the second reaction zone is fed into the third reaction zone, wherein the temperature at the input of each subsequent reaction zone is higher than the temperature at the input of each previous zone. The hydrocarbon fraction is 62-88 wt.% of the feedstock and the olefin-containing fraction is 7-33 wt.% of the feedstock. The flow temperature at the inlet to the first / second / third reaction zone is 330-350°C / 340-360°C / 350-370°C. The distribution of the second flow between the three reaction zones is 40-60 wt.% / 20-40 wt.% / 10-30 wt. %, the distribution of the third flux between the three reaction zones is 20-40 wt.% / 25-45 wt. % / 25-45 wt.%, catalyst distribution by reaction zones is 10-30 wt.% / 20-40 wt.% / 40-60 wt.% of the total catalyst for the first / second / third reaction zone respectively.EFFECT: technical result consists in increasing the yield of a liquid hydrocarbon product by 3-7 wt.% on the hydrocarbon raw material served, and increased selectivity in С5+hydrocarbon formation.25 cl, 6 tbl, 7 ex |
