Method for synthesis of zeolites from ashes formed from burning and co-burning of biomass

摘要

the object of the application is a synthesis zeolite from the ashes resulting from the incineration and co incineration of biomass of phosphatase or activation under conditions of high pressure charakteryzuju0105cy that to the pressure reactor is composition of fly ash containing in its chemical composition components of sio2 oxide, 20 to 60% by weight of al2o3, 2,1 - 13% by weight, which composition contains the ashes resulting from the incineration and co incineration or biomass, the following factor alkaline in quantities of from 1 to 20 ml per 1 g of fly ash.optional introduces modifying factors, the resulting mixture is mixed, initially raises the pressure in the reaction to the level of 0,1 - 0.6 mpa.maintains the reactionary in this state for the period from 2 to 10 minutes.then the system is heated to temperature above 70u00b0c reactionary at constant speed while increasing the pressure in the reaction system to a level above 1 mpa, preferably to a level 1.1 - 1.8 mpa and maintains a reactionary in this state for the period from 1 to 6 hours, then the reactionary cools at a constant speed, removes excess alkaline reaction system factor.and the product obtained is washed with water at elevated temperature, washing to a ph value in the water rinsing and then drying.with the compositions of volatile synthesis zeolite using materials such as fly ash from biomass burning in boilers and fluidalnych slatted ash fly;ne derived from co incineration of biomass boilers slatted and fluidalnych with coal, coal to biomass proportions from 100: 1 to 1: 100.the mixture formed by mixing the ashes to ashes volatile incineration or co incineration ashes from combustion of biomass and coal in appropriate proportions.
