Abstract

The invention discloses a method for preparing biomass gasified syngas. The method comprises the following steps: (1) adding neodymium chloride and promethium chloride into water, uniformly mixing andstirring, and adding sodium erucate to prepare a gasifying additive; (2) drying corn straws, adding rice husks into the dried corn straws, uniformly mixing, and grinding to prepare a biomass raw material; (3) mixing the biomass raw material, the gasifying additive and potassium fluotitanate, and drying to prepare a gasifying raw material; (4) performing cracking treatment on the gasifying raw material; and (5) treating the cracked syngas by adopting a settling ash hopper, introducing into a spray chamber, spraying a spray liquid from the upper part of the spray chamber for cooling treatment,and treating the syngas through a demister and a dryer. The method for preparing biomass gasifying syngas is simple and stable in process and low in cost, and can be used for effectively improving thegasifying efficiency of raw materials; and the gas prepared by the method has relatively high calorific value.

Description

technical field [0001] The invention belongs to the technical field of preparing fuel gas from biomass, and in particular relates to a method and equipment for preparing biomass gasification synthesis gas. Background technique [0002] Biomass gasification is under certain thermodynamic conditions, with the help of the air part (or oxygen) and water vapor, the biomass high polymer undergoes pyrolysis, oxidation, reduction and reforming reactions, and finally converted into carbon monoxide, hydrogen and low molecular weight hydrocarbons and other combustible gases. China has a huge amount of solid biomass available, mainly agricultural waste and wood waste. The distribution of biomass is scattered, and it is difficult to collect and transport. Under the current conditions in China, it is difficult to adopt large-scale combustion technology. Therefore, small and medium-scale biomass gasification power generation technology has unique advantages in China. Biomass is an import...
