Abstract
Gaseous unsaturated hydrocarbons, particularly ethylene and propylene, are prepared by cracking liquid hydrocarbons at 600-900 DEG C., in the presence of 20-200% by weight of steam in a fluidized bed of solid to which is added a small amount of a compound of an element of Group 1a or 2a of the Periodic Table. The liquid hydrocarbon may be a petroleum fraction, crude oil or residue. Normal pressure or increased pressure, e.g. 5-20 atmospheres may be used. Oxygen may also be added separately or mixed with the hydrocarbon. The solid material may be a synthetic or natural material containing magnesium, aluminium or silicon, e.g. sillimanite, corundum or magnesite, or carbon, e.g. high temperature coke anthracite, brown coal low temperature coke or oil coke, preferably that formed in the process. The added compound may be impregnated into the solid or added direct to the bed in solid, pulverulent form, particularly when coke is the solid. The solid may contain 0,01-1% of the element of Group 1a or 2a which is preferably added as the oxide or a compound forming the oxide such as the nitrate or carbonate. Specified elements are sodium, potassium, beryllium, calcium and magnesium. If the initial material contains sulphur this appears in the product as hydrogen sulphide and not the corrosive oxides.
