Abstract:
1. A new method for purification and conditioning of crude syngas based on properties of molten salts, comprising the following steps: (1) removing particles at a high-temperature by enabling the high-temperature crude syngas produced by a gasification device to firstly pass through a high-temperature particle removal device to remove solid particles in the gas; (2) removing hydrocarbons in the presence of oxygen by introducing an oxidant into the crude syngas after treatment in said step (1), selectively removing the hydrocarbons in the crude syngas and simultaneously utilizing high temperature produced by oxidation of the hydrocarbons to crack tar; and (3) removing gas pollutants and conditioning by introducing the crude syngas obtained in said step (2) into molten salts medium, removing pollutants containing sulfur and chlorine in the crude syngas, and simultaneously adjusting the H
