Relationships of the Production of Hydrogen-Containing Gas from Methane on a Pilot Installation with a Moving Bed of a Microspherical Catalyst and Separate Supply of the Feed and Oxidant

AbstractThe concept of a new technology for producing hydrogen-containing gas from methane is presented. The process is performed in two separate vessels, a reactor and a regenerator, between which a microspherical catalyst containing active lattice oxygen continuously circulates. The following parameters of oxidative methane conversion were reached in experiments on a pilot installation with a moving bed of a microspherical catalyst and separate supply of the feed and oxidant: methane conversion 95%, molar ratio Н2/СО = 2, catalyst performance (hydrogen output) 0.072 kghydrogen h–1 (kgcatalyst)–1. The possibility of producing a methane–hydrogen mixture free of carbon oxides under the conditions of low methane conversion at 550°С and the volumetric space velocity of the feed of 1.5 h–1 was demonstrated. The methane conversion under these conditions is 19.6%, and the hydrogen and methane concentrations are 38 and 61 mol %, respectively. The hydrogen output under these conditions is 0.038 kghydrogen h–1 (kgcatalyst)–1.
