Treatment and application method of nut waste

Abstract

The invention belongs to the technical field of agriculture and forestry waste biomass energy, and particularly relates to a treatment and application method of nut waste. According to the invention, a biochar catalyst is prepared by collecting biochar which is one of the products obtained by pyrolysis of nut waste, and then a modified biochar catalyst is prepared by loading cheap transition metal onto the biochar by utilizing a precipitation method. Then the modified biochar catalyst is returned to be applied to the catalytic pyrolysis reaction of the nut waste, high-quality bio-oil and charcoal are generated through the reaction, and the charcoal is modified to serve as a catalyst for the catalytic pyrolysis reaction of the nut waste, so that a circulating closed loop is formed. The mode of recycling the catalyst preparation material and the conversion product reflects the high-value full-quality utilization of the nut waste.

Description

technical field

[0001] The invention belongs to the technical fields of agricultural and forestry waste biomass energy conversion, resource utilization and chemical engineering, and specifically relates to a treatment and application method of nut waste. Background technique

[0002] Energy is an important material basis for the survival and development of human society. Throughout the history of the development of human society, every major progress of human civilization is accompanied by the improvement and replacement of energy. In recent years, renewable energy such as wind energy, nuclear energy, and solar energy has attracted people's attention, among which biomass (such as nut waste) is one of the most important renewable resources. These energies are stored in plants in nature. Plants use biomass as a medium to store solar energy in their bodies through photosynthesis, and the output of these biomass raw materials can reach hundreds of millions of tons per year. Ac...
