Gasoline oxidation reformation and hydrogenation catalyst

Abstract

The gasoline oxidation reformation hydrogen manufacturing catalyst is a loaded catalyst using one of Al2O3, ZrO2, TiO2, MgO and iolite as carrier, and is characterized by that RuO2 is used as main catalytic component, its content is 0.1-0.8 wt% of total weight of said catalyst, and one or several kinds of oxides of rare earth elements, oxides of alkaline earth metals and oxides of alkali metals are used as auxiliary catalytic component, and its content is 1-10 wt% of total weight of said catalyst.

Description

Technical field: [0001] The invention relates to hydrogen production by oxidative reforming of gasoline as a hydrogen source technology for a proton exchange membrane fuel cell (PEMFC), and particularly provides a catalyst for hydrogen production by partial oxidative reforming of gasoline. Background technique: [0002] With the maturity of proton exchange membrane fuel cell (PEMFC) technology, the research and development of its supporting hydrogen source has increasingly become an important factor restricting the commercialization of fuel cell electric vehicles.

"Studies on gasoline fuel processor system for fuel-cell poweredvehicles application", Applied Catalysis A: General 215(2001) 1-9), Document 2 (Wangyanhui, Wu diyong. "The experimental research for production of hydrogen from n-octane through partially oxidizing and steam reforming method", International Journal of Hydrogen Energy26 (2001), 795-800) tried to use traditional hydrocarbons (including naphtha, gasoline, etc.) Steam reforming hydrogen production catalysts (such as Ni-based catalysts) are applied to gasoline oxidation reforming hydrogen production process. It is found that under the oxidation reforming conditions, the traditional steam reforming The catalyst does not precipitate carbon under the condition of water-to-carbon ratio, and there is no mention of the catalyst's anti-sulfur poisoning performance

Document 3 (S.Ahmed, M.Krumpelt, et al, "Catalytic Partial OxidationReforming of ydrocarbon Fuels", Fuel Cell Seminar, California, 1998) attempts to replace gasoline components with a catalyst code-named A-C / α-γ (Isooctane) oxidative reforming hydrogen production research, its activity and selectivity are high, a 40h test was carried out with commercially available gasoline (unknown components), and it was found that the catalyst had better resistance to carbon evolution and sulfur poisoning , no further tests were carried out on the catalyst, such as the catalyst's oxidation resistance, thermal shock resistance, and longer-term stability investigation
