Methanol protein high-efficiency low-carbon production system and method based on biomass synthesis

Abstract

The invention discloses an efficient low-carbon methanol protein production system and method based on biomass synthesis, and relates to the technical field of bioengineering. Oxygen-enriched air obtained by compounding oxygen which is a byproduct of electrolytic hydrogen production with air is introduced into a fermentation tank, so that the production efficiency of methanol protein is improved; straw biomass ingredients are treated by a fluidized bed biomass gasifier, biomass synthesis gas is desulfurized and then participates in reaction to synthesize methanol, a byproduct CO2 obtained by methanol protein synthesis is supplemented to participate in reaction to synthesize methanol after decarburization trapping, purification, compression and recovery, energy conservation and environmental protection are achieved, and zero carbon emission is achieved; water electrolysis hydrogen production, biomass gasification furnace and methanol synthesis reaction heat are treated by a waste heat boiler to generate low-pressure superheated steam, the low-pressure superheated steam is respectively used for fluidized bed biomass gasification furnace, crude methanol rectification and subsequent methanol protein drying, rich waste heat is recovered to prepare saturated steam, and the saturated steam is output and can also be used for lithium bromide preparation process cooling water. When the environment temperature is too high in the fermentation process, cold energy is supplemented to a methanol protein synthesis system or is output as a cold source, so that the energy is further fully recycled.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a high-efficiency and low-carbon production system and method for methanol protein based on biomass synthesis. Background technique [0002] Methanol protein is a single-cell protein produced from methanol as a carbon source. The main components of methanol protein are crude protein, fat, lysine, methionine, cystine, minerals and vitamins, and the average content of crude protein is more than 70%. Methanol protein is called the second-generation single-cell protein. Compared with natural vegetable protein, methanol protein is richer in amino acids, minerals and vitamins, which can partially replace fish meal, soybean, meat and skimmed milk powder to feed poultry. The development of methanol protein is one of the important ways to solve the problem of protein shortage in my country's aquaculture and food industry, and it is of great strategic significance to solve the prob...

AI Technical Summary

Problems solved by technology

[0004] (1) The consumption of water, electricity and gas in the fermentation production process is large, high-density fermentation cannot be realized, the production efficiency is low, and the production cost is high;

[0005] (2) The raw material methanol consumes a large amount of carbon sources and emits a large amount of CO 2 At the same time, the fermentation production process also emits a large amount of CO 2 , which constitutes a serious carbon emission problem
