Problems solved by technology

[0002] In the production process of modern society, a large amount of waste biomass will be produced. Composting and incineration are mainly used for the treatment of waste biomass, but this method will generate a lot of smoke and waste energy.
At this stage, various thermochemical technologies (such as pyrolysis and gasification) convert biomass into high-value products, but in this process, the key problem of tar is inevitably generated

Abstract

The invention discloses a preparation method and an application of a biomass honeycomb semicoke loaded nickel-iron nanoparticle catalyst. According to the method, gulfweed is used as a raw material, feCl3.6H2O and NiCl2.6H2O are introduced to serve as a chemical activating agent and a metal endowing substance, gulfweed is mixed with a mixed solution of FeCl3.6H2O and NiCl2.6H2O according to a certain ratio for dipping, carrier gas N2 is introduced into a tubular furnace for heat treatment to directly convert the gulfweed raw material into an excellent catalyst with a high specific surface area, multiple active sites and a special honeycomb structure, and the catalyst is applied to the catalytic cracking process of biomass pyrolysis tar. The waste seaweed biomass is used for treating biomass pyrolysis tar, waste is treated with waste, the biomass growth cycle is short, the preparation process is simple, the cost is low, environmental pollution is small, and the prepared gulfweed carbon-based honeycomb catalyst achieves a stable and ideal effect in biomass tar catalytic cracking.

Description

technical field [0001] The invention belongs to the technical field of energy and chemical industry for environmental protection and utilization of biomass solid waste, and specifically relates to a preparation method and application of a biomass honeycomb semi-coke loaded nickel-iron nano particle catalyst. Background technique [0002] In the production process of modern society, a large amount of waste biomass will be produced. Composting and incineration are mainly used for the treatment of waste biomass, but this method will generate a lot of smoke and waste energy. At present, various thermochemical technologies (such as pyrolysis and gasification) convert biomass into high-value products, but in this process, the key problem of tar is inevitably generated. At present, the treatment of tar includes two methods of physical cleaning and chemical conversion. Among them, the physical cleaning method is easy to cause environmental pollution and energy waste, and the chemic...
