Abstract
In a process for the production of gaseous olefines by the partial oxidation of gaseous or vaporous saturated hydrocarbons having at least 2 carbon atoms in the molecule, the mixed gases are led through a free space in which their speed undergoes reduction by at least one half, then through a thin loose layer as defined below of a heat-stable, inert, granular material, and are reacted in a fluidized bed of an inert, heatstable solid. By a thin layer is meant one through which a gas does not undergo any marked loss in pressure and in which the residence time is so short that a surface combustion cannot fully develop under the conditions employed; the grain size may be 5 to 20 mms. and the layer thickness 5 to 20 cms. The speed of the mixed gases in the free space is preferably reduced to less than one-fifth. Atmospheric, increased or reduced pressures e.g. up to 30 atmospheres at 600-1000 DEG C. may be used. Oxygen-containing gases such as air may be used as the oxidizing gas and steam may be added. In an example propane, oxygen and steam are passed through a fluidized layer of sillimanite at 600 DEG C. yielding a cracking gas rich in ethylene. The reactants prior to passing through the fluidized bed pass through a conical space where the speed is reduced and an 8 cms. deep layer of 5 mms. diameter porcelain balls.
