Mhinduro yekupindura (RSM) yaishandiswa kudzidza iyo nitric acid kusimuka kwekusveta co mo best hydrotreating catalyst. Chinangwa cheichi chidzidzo chaive chekusvitsa co uye mo kubva kuimba yakashandiswa mumhando yemvura uye yekupora, uye ziva kusarudzika kwekushandiswa kwemarara yakasimba, maitiro ekudzidzira uye ekudzidzira tembiricha. Zvinokurudzira chaizvo zvinhu zvaive zvakatemwa nekupindura nzira yekupokana, uye kuenzana kwemuenzaniso wekuita paramita uye cobalt uye molybdened rate yakamisikidzwa yakatangwa. Pasi pemamiriro ezvinhu akakwana akawanikwa nemuenzaniso, iyo cobalt yekuregerera yaive inopfuura 96%, uye iyo molybdened rate yakadarika 97%. Yairatidza kuti paramita yakaringana yakawanikwa nemhinduro yekupindura yaive chaiyo uye yakavimbika, uye inogona kushandiswa kutungamira maitiro chaiwo ekugadzira
