Study on the Adhesion Characteristics Control and Slurry Characteristics of F-T Waste Catalyst
F-T solid waste is composed of oily iron based waste catalyst and stable slag wax,which contains 55%～65%wax components and belongs to dangerous waste.In this paper,by blending F-T solid waste with coal powder in coal water slurry gasification unit,the regulation of adhesion characteristics of F-T solid waste was studied respectively,and the apparent viscosity and static stability of coal water slurry slurry with F-T solid waste were added to provide reliable experimental data for blending F-T solid waste in gasification unit and realizing resource utilization.The results show that adding alkyl phenol polyoxyethylene ether or sodium dodecyl benzene sulfonate can effectively improve the adhesion properties of F-T solid waste.At the same slurry concentration,the apparent viscosity of CWS containing F-T solid waste increases with the increase of solid waste content.When 10%F-T solid waste is added,the maximum slurry concentration of CWS decreases from 62.2%to 60.7%.
