Problems solved by technology

[0004] Due to the high carbon content in gasoline, when the reforming reaction occurs on conventional Ni-containing catalysts, both initial activity and durability are not ideal
It is easy to deposit carbon on the surface of the catalyst, block the pores, and reduce the activity of the catalyst

Abstract

The invention provides a catalyst for steam reforming of gasoline to produce hydrogen and a preparation method thereof. The catalyst comprises a carrier component, active components and a co-catalysis component, wherein the carrier component comprises at least one selected from Al2O3, ZrO2, TiO2, MgO and cordierite, and the mass ratio of the carrier component is 50-93%; the active components are NiO and RuO2, and the mass ratio of the active components is 5-30%; and the co-catalysis component comprises at least one selected from rare earth element oxide, alkaline earth metal oxide and alkali metal oxide, and the mass ratio of the co-catalysis component is 2-20%. The catalyst is prepared by three times of impregnation, and has the advantages of high catalytic activity, high gasoline conversion rate, good carbon deposition resistance, strong sulfur poisoning resistance, good high-temperature stability and the like.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a gasoline steam reforming hydrogen production catalyst and a preparation method thereof. Background technique [0002] Proton exchange membrane fuel cell (PEMFC) is a high-efficiency and environment-friendly technology, which has the advantages of no pollution emission, high efficiency, no noise, fast startup, etc. It has broad application prospects in the fields of transportation, communication, backup power and other energy sources, and industrial gases . Since hydrogen storage technology is still far away from practical application, the research and development of hydrogen production system based on hydrocarbon reforming has become the most challenging hot topic of fuel cells. [0003] Gasoline has a high energy density, and its production, transportation, storage, distribution and other infrastructures are complete. Therefore, the mobile or stationary hydrogen producti...
