Oxidative Cracking of Oil Refinery Gases

Аннотация

Trials of oxidative cracking of ethane—propane—n-butane mixtures were performed on an installation with the productive capacity with respect to the gaseous feed of 5 m³ h⁻¹. Ethylene, CO, and hydrogen are the major products of oxidative cracking of oil refinery gases; their total yield can exceed 90%. The yield of ethylene and CO is determined by the total concentration of alkanes in the mixture and is independent on the length of their hydrocarbon chain, whereas the hydrogen yield appreciably decreases with an increase in the alkane chain length. The trials demonstrated high efficiency of the production of ethylene, CO, and hydrogen by oxidative cracking of oil refinery gas mixture components.
