Abstract

The biomass hydrogenation liquefaction catalyst described in the present invention is an iron-based desulfurizer waste agent, and the active component of the iron-based desulfurizer waste agent is FeS 2 , the FeS 2 The content is 10wt%-70wt% based on the content of iron element. FeS 2 Biomass hydrogenation as an active component, not only has a good hydrogenation effect on biomass, the fraction of ≤350 °C reaches 89%, and FeS 2 The property is stable and will not spontaneously ignite during the grinding process, which improves the safety performance of the catalyst; on the other hand, the hydrogenation catalyst uses waste desulfurization agent as raw material, turning waste into treasure, and avoiding environmental pollution caused by waste desulfurization agent , greatly reducing the cost of biomass hydrogenation.

Description

technical field [0001] The invention relates to the technical field of biomass hydrogenation, in particular to a biomass hydrogenation liquefaction catalyst, a preparation method and a biomass liquefaction method. Background technique [0002] Coal, crude oil, natural gas, oil shale and other fossil non-renewable energy sources are becoming increasingly exhausted with the rapid development of social economy, and the CO produced after their combustion 2 , SO 2 , NO x The increasingly serious environmental pollution caused by such pollutants has forced human beings to seriously consider ways to obtain energy and methods to improve the environment. Biomass is a kind of renewable energy, which has huge potential and advantages in meeting energy demand, reducing environmental pollution, and improving energy structure. Biomass refers to all organic substances formed by photosynthesis of green plants that can be directly or indirectly used , including plants, animals, microorgan...
