Hydrogen production catalyst prepared from waste commercial vanadium titanium denitration catalyst and preparation method

Abstract

The invention discloses a hydrogen production catalyst prepared from a waste commercial vanadium titanium denitration catalyst and a preparation method. The hydrogen production catalyst uses ceramic granules as a carrier and nanogold as a catalytic active component; the ceramic granules are prepared from the waste commercial vanadium titanium denitration catalyst, diatomite, pseudo-boehmite and amoulding agent; the ceramic granular catalyst comprises the following components according to a mass ratio of the waste commercial vanadium titanium denitration catalyst, the diatomite, the pseudo-boehmite, the moulding agent and the catalytic active component of (80-90):(2-4):(1-5):(6-7):(0.1-0.5). The prepared hydrogen production catalyst not only can achieve high-added value resource utilization of the waste commercial vanadium titanium denitration catalyst, but also is applicable to a reforming hydrogen production reaction of small organic molecules such as methanol, has the advantages ofhigh H2 selectivity, small low active component load, low cost and the like and is wide in application prospect, namely, the hydrogen production catalyst has major social and economic benefits such asenvironmental protection, turning of wastes into treasures and the like.

Description

technical field [0001] The invention provides a method for preparing a hydrogen production catalyst by using a waste commercial vanadium-titanium denitrification catalyst, which belongs to the field of resource utilization of waste products. Background technique [0002] Nitrogen oxides are the main cause of pollution such as smog and acid rain. The denitrification of industrial flue gas such as thermal power plants has become the focus of current air pollution control. The average life of the catalyst is 3-5 years, and the vanadium-titanium denitrification catalyst needs to be replaced when the time is up. Therefore, the regeneration treatment or resource utilization of waste vanadium-titanium denitrification catalysts has become an environmental protection problem that needs to be solved urgently. On this basis, the high value-added resource utilization of waste vanadium-titanium denitrification catalysts will be a feasible and economical conversion method. [0003] Appl...
