Zvakasara zve hydrotreating process-catalyst raw material pseudo boehmite

Maitiro ekugadzirisa mvura yakasara maitiro ekugadzirisa mvura yakasara nemubhedha wakatarwa akadzidzwa uye akapfupikiswa, uye maitiro anotevera akapfupikiswa: Chekutanga, mubhedha wekugadzirisa akasiyana kana zvikamu zvakasiyana zvemubhedha mumwe chete pane musiyano pakati pe1) maitiro ekugadzirisa mvura ndeye exothermic reaction, mu industrial reactor, kukwira kwekushisa mumubhedha mumwe chete, mubhedha wepamusoro 2) tembiricha yakaderera yekuita yakakwira reactive substance pakutanga mumubhedha wepamusoro kana mubhedha wekutanga reaction, uye reaction material pasi pemubhedha kana inotevera reaction 3) upper bed reactant concentration yakakwira, uye mubhedha wepasi reactant concentration yakaderera kana kushandurwa kwemubhedha wepamusoro kwakakwira, mutoro wakakura 4) hydrotreating reaction uye kugadzira hydrogen sulfide uye ammonia, hydrogen consumption chikonzero mubhedha wepamusoro nepasi weH2 concentration yeH2S neNH3 yakasiyana yechipiri, mafuta akasara ane huwandu hwakawanda hwetsvina uye zvikamu zvisina kunaka, avhareji yayo molecular weight, high viscosity, zvichitungamira kune yakaderera reaction performance, catalyst deactivation, saka residue hydrotreating process operating conditions inoda, high pressure uye tembiricha, space velocity yakaderera yechitatu, residue yakagadzirwa Mukuita kwehydrogenation yemubhedha wakagadzirwa, coke yakawanda nesimbi sulfide nezvimwe zvinhu zvakasimba, kuiswa kwezvinhu zvakasimba mumubhedha kuchaita kuti musiyano wekumanikidzwa kwemubhedha uwedzere kusvika pamuganhu wekugadzira wasvika, mudziyo wakamanikidzwa kudzima. Chechina, maitiro ekugadzirisa mvura anoshandiswa anofanira kushandisa tekinoroji yekurodha zvinhu zvinosanganisa catalyst.
