Catalyst for hydrogen production by catalytic reforming with biological oil and preparation method

Abstract

The invention relates to a catalyst for hydrogen production by catalytic reforming with biological oil and a preparation method. The catalyst comprises catalyst active components and a catalyst carrier; the catalyst active components refer to the following components in percentage by weight of 10-15 wt% of Ni, 5-13 wt% of Mo, 5-10 wt% of Fe and the balance being attapulgite and sepiolite mixed clay pit catalyst carrier. The catalyst provided by the invention has the advantages of large surface area, strong absorption function and strong promotion function; the cheap and easiest available attapulgite and sepiolite mixed clay pit are used as the catalyst carrier; and the catalyst active components comprise nickel, molybdenum and iron composite components, so that the molecules of the biological oil are subjected to splitting and chain scission to form high-quality synthesis gas of low-molecule hydrocarbon and high-content hydrogen. The catalyst provided by the invention has the advantages of simple catalyst preparation, large strength, strong catalyst activity, and regeneration. Not only can the catalyst be used for hydrogen production by catalytic reforming with the biological oil, but also the catalyst can be applied to direct hydrogen production by catalytic gasification with biomass.

Description

technical field

[0001] The invention relates to a bio-oil catalytic reforming hydrogen production catalyst and a preparation method thereof, that is, a method for preparing a catalyst for high-quality gas fuel by using bio-oil catalytic reforming hydrogen production from biomass cracking. Background technique

[0002] The use of biomass to produce hydrogen is not only an effective use of abundant renewable resources, but also one of the effective ways to finally solve the huge environmental pollution caused by global fossil fuels. my country's fossil fuel resources are short and biomass resources are very rich. How to clean it cheaply? The efficient conversion of biomass into hydrogen fuel, the core power of the future hydrogen energy society, is of great significance to the sustainable development of our country. Biomass is highly dispersed and low in energy density, which determines the high cost of collection and transportation and poor economics in the process. Rapid pyro...
