Abstract

The 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 kg_hydrogen h^–1 (kg_catalyst)^–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 kg_hydrogen h^–1 (kg_catalyst)^–1.

在带有微球催化剂移动床的中试装置上由甲烷生产含氢气体与进料和氧化剂分开供应的关系

摘要

提出了一种由甲烷生产含氢气体的新技术的概念。该过程是在两个独立的容器中进行的，分别是反应器和再生器，含活性晶格氧的微球催化剂在其中连续循环。氧化甲烷转化的以下参数中的实验达到上的导频安装有微小球状的催化剂和原料和氧化剂的单独的供给的移动床：甲烷转化率95％，摩尔比Н ₂ /СО= 2，催化剂的性能（氢输出）0.072公斤_氢气h ^–1（公斤_催化剂）^–1。证明了在低甲烷转化率（550°С）和进料的体积空速为1.5 h ^–1的条件下生产不含碳氧化物的甲烷-氢混合物的可能性。在这些条件下的甲烷转化率为19.6％，并且氢气和甲烷的浓度分别为38和61mol％。在这些条件下的氢气输出为0.038 kg_氢气h ^-1（千克_催化剂）^-1。
