Selective removal method of the FT catalyst which the inside of the FT synthetic oil pulverizes

摘要

PPROBLEM TO BE SOLVED: To solve a problem in that although a residual catalyst contained in an Ft synthetic crude oil is recovered and reused and also the synthetic oil with reduced residual catalyst is obtained, since the catalyst is pulverized, it has a bad influence for the characteristics of reactivity, etc., of the synthesis. PSOLUTION: By making the magnetic separation process as 2 stage separation processes, in a first liquid solid separation process, the catalyst having a large particle diameter is recovered and reused, and in a second liquid solid separation process, the pulverized residual catalyst is separated and discharged to the outside of a system. Thus, the FT synthetic oil reduced with the residual catalyst is obtained. PCOPYRIGHT: (C)2010,JPO&INPIT
