Abstract

Hydrocarbon conversion processes (pref. thermal cracking of crude oil, gas oil or naphtha) are carried out by (a) passing a process gas stream contg. the substances to be reacted and preheated sand in countercurrent downwards through a vertical reactor; (b) sepg the gaseous effluent from the sand by withdrawing it through an outlet laterally displaced from the path of the sand; and (c) opt. quenching the effluent, pref. in fluidised bed of sand particles. The "sand" can be Al2O3, SiO2, SiO2-Al2O3 and/or any other refractory oxide with a particle size of 0.01-1 (esp. 0.1-0.5)mm. The sand can be recovered and recycled after burning off coke deposits.
