Abstract
<PICT:0759720/III/1> In coking heavy hydrocarbons by contacting them with preheated finely divided fluidized solid particles, the maximum feed rate of oil to the bed without causing agglomeration is determined by a equation based on the facts that the rate is inversely proportional to the coke deposited and that this coke yield is proportional to the Conradson carbon number of the feed. Sand, pumice, metal shot, glass or ceramic beads &c. may be used but coke of 40-500 microns diameter derived from the process is preferred for the bed and partially burnt to provide a bed temperature of e.g., 800 DEG -1000 DEG F for a maximum yield of gas oil. Apparatus comprises a preheater 11 from which the solids are conveyed by steam, nitrogen, &c. through a line 13 to a coking vessel 15. Oil, preferably preheated to below cracking temperature, is supplied through valved nozzles 20 into the bed the level of which is determined by a partition 25 defining a stripping zone 27, solids returning therethrough and through a line 37 to the heater assisted by air, &c. admitted at points 41. Gas or oil fuel may be supplied to reduce or eliminate coke combustion. Coking bed temperatures of 900 DEG -1050 DEG F are preferred and with feed preheat of 600 DEG -800 DEG F and aerating velocity of 0.5-1.2 ft. per sec. a maximum coke deposit of 0.35 lb. per hour per lb of fluidized solids may safely be reached. Increases of 30 DEG -50 DEG F in coking temperature enable the oil feed rate to be doubled.
