Abstract

The invention relates to the technical field of bioenergy, in particular to a hydrogenation catalyst composition and its application. The invention provides a catalyst for combined use, including catalyst A and catalyst B, both catalyst A and catalyst B are supported by dry distillation biomass charcoal, and catalyst B is used in conjunction with a vulcanizing agent; the active component of catalyst A is iron oxide , one or more of iron hydroxides, the active component of catalyst B is one or more of the oxides of Mo, W, Fe, Co, Ni, and the metal active component can effectively activate hydrogen and Deoxidation, inhibit coking, improve product oil quality. The combined use of the catalyst provided by the invention is applied to the hydrogenation of the biomass slurry bed / suspension bed, which expands the application field of the biomass charcoal, and the catalyst is easy to recover and can be recycled.

Description

technical field [0001] The invention relates to the technical field of bioenergy, in particular to a biomass slurry bed / suspension bed hydrogenation catalyst composition and its application. Background technique [0002] The rapid development of the world economy has benefited from the wide application of fossil energy, such as oil, natural gas, and coal. With the continuous consumption of non-renewable fossil resources, and the CO produced by their combustion 2 , SO 2 , NO x Pollutants such as pollutants have caused increasingly serious environmental pollution, and the development of renewable new energy has become a top priority. Biomass is a kind of renewable energy. It is organic matter rich in carbon, hydrogen and oxygen that is directly or indirectly transformed through photosynthesis, including plants, animals, microorganisms and their excretion and metabolites. It is renewable, low-polluting, Widely distributed, it has great potential and advantages in meeting en...
