Study on Engineering Development of Novel Technology of Methanol Synthesis in Three-Phase Slurry Reactor

A hot flow test set up was installed based on a lot of basic researches.Three phase methanol synthesis was carried out over C3O2 copper based catalyst suspended in medical liquid paraffin used for as inert liquid medium at the temperature ranging 210℃ to 255℃ and the pressure ranging 2.5MPa to 3.2MPa in a bubble column slurry reactor with the diameter of 0.203m and the height of 8.2m.Operating performance of the whole hot flow test set up,the activity of catalyst,and the effects of main operating parameters on methanol synthesis process were investigated emphatically in the test.The test results show that the test set up can satisfy the demand of design,and that the problem of quickly rated catalyst deactivation at the condition of CO rich synthetic gas has effectively been solved.Besides,the reasons of catalyst deactivation and the other engineering problems were analyzed and discussed.
