Title:
METHOD FOR REDUCING RISK OF BURNING AND EXPLOSION IN DEOXYGENATION PROCESS OF OXYGEN-CONTAINING GAS
Document Type and Number:
WIPO Patent Application WO/2023/020044
Kind Code:
A1
Abstract:
A method for reducing the risk of burning and explosion in a deoxygenation process of an oxygen-containing gas. The method comprises: in the presence of a gaseous alkane, mixing an oxygen-containing gas from which an unsaturated hydrocarbon is removed with hydrogen, so that oxygen in the oxygen-containing gas undergoes an oxidation reaction with the hydrogen, wherein the oxygen-containing gas contains the oxygen and the unsaturated hydrocarbon, and the content of the oxygen in the oxygen-containing gas is greater than 0.5% by volume. A gaseous alkane is introduced to reduce the risk of burning and explosion of a mixed gas; a hydrocatalytic reaction is carried out to promote oxygen in the mixed gas to react with hydrogen to produce water, such that the purpose of deoxygenation of an oxygen-containing gas is achieved and the reaction product is clean; and the hydrocatalytic reaction can effectively inhibit the occurrence of carbon deposition on the surface of a catalyst and the production of a carbon oxide, and a strong endurance for fluctuation of the oxygen content in a raw gas is provided.
