PROCESS FOR TREATING CATALYTICALLY CRACKED GASOIL

摘要

the invention relates to a processing process of catalytic cracking of petrol, in order to increase the number octanice engine. the process according to the invention consists in that mix the fraction of catalytic cracking with the distillation range 30...214u00b0c and a sulphur content of 300...350 ppm to 1% by weight of methyl ethyl ketone in a knot of mixture, the product heated to temperature of 175 and 190u00b0c, after which follows the reaction, which is conducted in a reactor in the presence of phosphoric acid on the catalyst support volumaru0103 kieselgur, with hourly speed of 15... 25 m # 3 # feedstock / m # 3 # catalyst / h, pressure of 2...at 5, in which the catalyst is umectat beforehand with methyl ethyl ketone, after which, at the exit of the reactor, the gas is treated by a cooler temperature u0155 until 30...35u00b0c.
