Waste FCC catalyst ceramic membrane support and preparation method and application thereof
A waste FCC catalyst ceramic membrane support and a preparation method and application thereof belong to the technical field of wastewater purification. The preparation method of the waste FCC catalyst ceramic membrane support comprises the following steps of molding mixed raw materials and carrying out sintering. The sintering process comprises the steps of heating to 1150-1240 DEG C and keepingthe temperature for 1-3 hours. Raw materials comprise a waste FCC catalyst and a forming aid. The mass of the forming aid is 3-10% of the mass of the waste FCC catalyst. According to the invention, the waste FCC catalyst ceramic membrane support with high mechanical strength, porosity of 30-50%, pore diameter of 1-5 [mu] m and good permeability can be prepared. The waste FCC catalyst contains someheavy metals such as nickel, iron, vanadium and oxides thereof, and is a good ozone catalyst, and the waste FCC catalyst has a large specific surface area, so that the ceramic membrane support prepared from the waste FCC catalyst can be applied to wastewater purification by ozone.
一种废FCC催化剂陶瓷膜支撑体及其制备方法和应用，属于废水净化技术领域。废FCC催化剂陶瓷膜支撑体的制备方法包括：将混合的原料成型后烧结。烧结包括升温至1150～1240℃后保温1～3h。原料包括废FCC催化剂和成型助剂。成型助剂的质量为废FCC催化剂的质量的3～10％。本申请能够制得机械强度高、孔隙率为30～50％、孔径为1～5μm且渗透性好的废FCC催化剂陶瓷膜支撑体。由于废FCC催化剂中含有一些重金属，例如镍、铁、钒及其氧化物，是良好的臭氧催化剂，并且废FCC催化剂具有较大的比表面积，使采用废FCC催化剂制成的陶瓷膜支撑体能够应用到臭氧净化废水中。
