Ni-B-La catalyst for bio-oil catalytic reforming hydrogen production and preparation method thereof

Abstract

The invention discloses Ni-B-La catalyst for bio-oil catalytic reforming hydrogen production and a preparation method thereof. The Ni-B-La catalyst comprises a catalyst active component, a catalyst auxiliary agent and a catalyst carrier, the catalyst active component is Ni, and the weight is 5-20% of the total weight of the Ni-B-La catalyst; the catalyst auxiliary agent is La2O3, WO3, SnO2, K2O and B2O3, the weight of La2O3 is 5-15%, of the total weight of the Ni-B-La catalyst, the weight of WO3 is 1-5% of the total weight of the Ni-B-La catalyst, the weight of SnO2 is 0.5-2% of the total weight of the Ni-B-La catalyst, the weight of K2O is 0.1-0.5% of the total weight of the Ni-B-La catalyst, and the weight of the B2O3 is 0.5-3% of the total weight of the Ni-B-La catalyst; the catalyst carrier is Al2O3, and the weight is the balance; the catalyst has the advantages that the preparation process of the Ni-B-La catalyst is mature, reliable and easy to operate, selected raw materials arewidely available, the price is low, anti-sintering and anti-coking performance is good, stability is strong, reactivity is high, life is long, conversion rate of bio-oil is high, and the hydrogen yield is high.

Description

technical field [0001] The invention relates to a catalyst and a preparation method thereof, in particular to a Ni-B-La catalyst used for catalytic reforming of bio-oil to produce hydrogen and a preparation method thereof. Background technique [0002] With the aggravation of the global shortage of fossil fuels and the deterioration of environmental pollution caused by the burning of fossil fuels, it is urgent to seek a sustainable supply of clean and efficient energy fuels. Biomass-based hydrogen just meets this requirement. Biomass-based hydrogen feedstock is widely distributed, CO 2 Net zero emissions, renewable biomass, and its combustion product is clean water, zero pollution to the environment, so it is known as one of the clean energy sources with the most development potential in the 21st century. [0003] Bio-oil catalytic reforming technology is an efficient and economical biomass-based hydrogen production technology. This technology is the process of obtaining ...

Problems solved by technology

[0006] However, the existing bio-oil catalytic reforming hydrogen production technology, on the one hand, when the bio-oil is catalytic reforming hydrogen production, on the one hand, because the life of the reforming catalyst is difficult to exceed 10 hours, this greatly restricts the industrialization of the reforming process. ; On the other hand, carbon deposition and sintering can easily lead to deactivation of the reforming catalyst
