Abstract
The present invention relates to a kind of cobalt-base catalyst of acetic acid self-heating reforming hydrogen manufacturing and preparation method.The present invention is directed to existing the catalyst change of catalyst structure and the oxidation of active component and sintering during acetic acid self-heating recapitalization, and there is provided a kind of resistance to sintering, anti-carbon deposit, resistance to oxidation, active high new catalyst the problem of cause catalyst inactivation.The chemical composition of the catalyst of the present invention is CoaZnbAlO7.5 + δ, wherein a is that 0.25 1.00, b is 0.75 5.00.The present invention uses coprecipitation method to be prepared for Zn Al type stratiform hydrotalcite-like compounds for presoma, and introduces active component cobalt, by same order elements of the cobalt to zinc, enters the veneer structure of hydrotalcite-like compound;The composite oxides of fired acquisition, effectively inhibit active component cobalt possible migration, aggregation and sintering under the conditions of pyroreaction, improve the heat endurance of catalyst;Carrier zinc oxide improves the reproducibility, stability and inoxidizability of active component cobalt simultaneously, so as to improve the activity and stability of catalyst.
Description
Technical field
The present invention relates to a kind of cobalt-base catalyst and preparation method for acetic acid self-heating recapitalization hydrogen making, more specifically
Say, be related to a kind of presoma with hydrotalcite-like compound, and cobalt-base catalyst for acetic acid self-heating recapitalization hydrogen making and
Preparation method, belongs to the technical field of acetic acid self-heating recapitalization hydrogen making.
Background technology
Hydrogen is a kind of energy carrier of cleaning, and be particularly suitable for use in fuel cell, is considered as the clean energy resource of future ideality
Carrier.At present, hydrogen is mainly produced from the conversion of the primary energy such as natural gas, coal, and which results in CO in atmosphere2The increasing of content
It is many.The biomass obtained by photosynthesis of plant, is a kind of important regenerative resource.However, biomass energy metric density is low, can
It is changed into energy density through fast pyrolysis and reaches 20 MJ/m3Bio-oil, then concentrate the inexpensive preparing hydrogen of scale conversion
