Nrog rau kev txhim kho tas mus li ntawm lub ntiaj teb refining muaj peev xwm, cov khoom lag luam nruj zuj zus ntxiv, thiab kev nce ntxiv hauv kev thov rau cov khoom siv tshuaj raw khoom, kev noj cov tshuaj refining catalysts tau nyob rau hauv kev loj hlob tsis tu ncua. Ntawm lawv, qhov kev loj hlob sai tshaj plaws yog nyob rau hauv kev lag luam tshiab thiab cov teb chaws tsim.
Vim muaj cov khoom sib txawv, cov khoom siv thiab cov qauv tsim ntawm txhua lub refinery, rau kev siv ntau lub hom phiaj catalysts kom tau cov khoom zoo tshaj plaws los yog cov khoom siv tshuaj raw khoom, kev xaiv cov catalysts nrog adaptability zoo dua los yog selectivity yuav daws tau cov teeb meem tseem ceeb ntawm cov refineries sib txawv thiab. cov khoom siv sib txawv.
Nyob rau hauv xyoo tas los no, nyob rau hauv Asia Pacific, Africa thiab Middle East, tus nqi noj thiab kev loj hlob tus nqi ntawm tag nrho cov catalysts, xws li refining, polymerization, tshuaj synthesis, thiab lwm yam yog siab tshaj ntawm cov cheeb tsam tsim nyob rau hauv Teb chaws Europe thiab lub tebchaws United States.
Nyob rau hauv lub neej yav tom ntej, kev nthuav dav ntawm roj av hydrogenation yuav yog qhov loj tshaj plaws, ua raws li nruab nrab distillate hydrogenation, FCC, isomerization, hydrocracking, naphtha hydrogenation, hnyav roj (cov roj residual) hydrogenation, alkylation (superposition), hloov kho, thiab lwm yam. catalyst xav tau kuj yuav nce correspondingly.
Txawm li cas los xij, vim qhov kev siv sib txawv ntawm ntau yam roj refining catalysts, tus nqi ntawm cov roj refining catalysts tsis tuaj yeem nce ntxiv nrog kev nthuav dav. Raws li kev lag luam kev lag luam txheeb cais, kev muag khoom feem ntau yog hydrogenation catalysts (hydrotreating thiab hydrocracking, accounting rau 46% ntawm tag nrho), ua raws li FCC catalysts (40%), tom qab los ntawm kev hloov kho catalysts (8%), alkylation catalysts (5%). thiab lwm yam (1%).
