Method for producing low potassium woody biomass ash, potassium reduction method of woody biomass ash, method for producing cement, and method for cement cement of woody biomass ash

摘要

Problem to be solved: to provide a method for producing a new low potassium woody biomass ash capable of obtaining a woody biomass ash reducing potassium from woody biomass ash.Manufacturing method of low potassium woody biomass ash to obtain woody biomass ash with reduced potassium content from woody biomass ashHeating woody biomass ashes from 500 to 850 degrees CelsiusA first step of contacting a woody biomass ash with a gas containing hydrogen chlorideAfter washing, woody biomass ash is washed with waterComprises a second step of removing the soluble contentManufacturing method of low potassium woody biomass ash.No selection
