Embodiment 1

[0018] Impregnation method: First, according to the mass percentage of the active component load as 1%, accurately weigh the quantitative nickel nitrate powder, put it in a beaker, and place it on a constant temperature magnetic stirrer; drop a quantitative amount of deionized water to prepare Saturated solution; then weigh quantitative MgCl 2 , immersed in the above saturated solution; turn on the magnetic stirrer, stir at 20°C for 20min to fully mix; then place the beaker in an oven for 4h at 80°C, then place the dried powder in a crucible at 700°C Roast for 12 hours; take out after cooling to obtain the target catalyst.

Embodiment 2

[0020] Citric acid complexation method: First, according to the mass percentage of the active component load as 5%, accurately weigh the quantitative ferric sulfate and sodium chloride powder and put them in a beaker, add deionized water to make a saturated solution; open Heat the constant temperature magnetic stirrer to 90°C; add a certain amount of citric acid monohydrate according to the cation: citric acid molar ratio of 1:1, stir well until the solution is nominally gel; dry the above gel at 120°C for 12 hours; then bake at 600°C After 6h, it was taken out after cooling to obtain the target catalyst.

Embodiment 3

[0022] Sol-gel method: First, according to the mass percentage of the active component load as 0.05%, accurately weigh the quantitative copper acetate and potassium chloride powder and put them in a beaker, add deionized water to make a saturated solution; turn on the constant temperature Heat the magnetic stirrer to 90°C; weigh 30% of the mass of the carrier to weigh a quantitative amount of pseudoboehmite, add it to the solution and stir, then add concentrated nitric acid solution dropwise until the liquid is transparent and form a colloid, stir for 2 hours; dry at 80°C for 12 hours Gel; finally, calcined at 800°C for 1 hour, cooled and taken out to obtain the target catalyst.

Abstract

The invention relates to a catalyst for hydrogen production from reforming and a preparation method thereof. The catalyst employs one or several kinds of metal oxides of Ni, Fe, Cu, Zn, Ce, La or Co as active components, and employs one of NaCl, MgCl2, KCl, MgSO4 or Na2SO4 as a carrier; the mass of the carrier is used as a reference, and the mass percentage content of active component loading is 0.05-30%. The preparation method could be an immersion method, a citric acid complexation method, a sol-gel method or a supercritical high temperature high pressure synthesis method, and preferably a supercritical high temperature high pressure synthesis method. The catalyst is suitable for hydrogen production reactions from reforming of various kinds of organic compounds, and the method has the advantages of high H2 selectivity, long usage life, low active component loading, low cost, reproduction, wide application prospects, and the like. The catalyst also can be used for converting waste oil and other organic pollutants into hydrogen; and the catalyst is environmentally friendly, can change waste into valuables, and has great social and economic benefits.

Description

Technical field: [0001] The invention relates to a reforming hydrogen production catalyst and a preparation method thereof, belonging to the technical fields of new materials, industrial catalysis and new energy. Background technique: [0002] With the global energy shortage and environmental pollution becoming more and more serious, the development and utilization of clean energy is imminent. Hydrogen, as a clean, efficient and renewable energy, is attracting extensive attention from researchers around the world. [0003] Commercial hydrogen production processes mainly fall into three categories: water electrolysis, coal gasification, and catalytic reforming, among which catalytic reforming is one of the hydrogen production processes with the greatest development potential. At present, the hydrogen sources of the catalytic reforming hydrogen production process are mainly methane, ethanol, methanol, etc. These hydrogen sources themselves are combustible, and their energy co...
