Nrog rau kev txhim kho tas mus li ntawm lub peev xwm ua kom huv thoob ntiaj teb, cov qauv khoom siv roj uas nruj zuj zus, thiab kev nce ntxiv ntawm qhov xav tau cov khoom siv tshuaj lom neeg, kev siv cov tshuaj ua kom huv tau nyob rau hauv qhov sib txawv ntawm kev loj hlob. Ntawm lawv, kev loj hlob sai tshaj plaws yog nyob rau hauv cov teb chaws tshiab thiab cov teb chaws uas tseem tab tom txhim kho.
Vim yog cov khoom siv raw sib txawv, cov khoom lag luam thiab cov qauv khoom siv ntawm txhua lub chaw ua roj, rau kev siv cov catalysts ntau dua kom tau txais cov khoom zoo tagnrho lossis cov khoom siv tshuaj lom neeg, kev xaiv cov catalysts nrog kev hloov pauv zoo dua lossis kev xaiv tuaj yeem daws cov teeb meem tseem ceeb ntawm cov chaw ua roj sib txawv thiab cov khoom siv sib txawv.
Nyob rau xyoo tas los no, hauv Asia Pacific, Africa thiab Middle East, qhov kev siv thiab kev loj hlob ntawm txhua yam catalysts, suav nrog kev ua kom huv, polymerization, tshuaj synthesis, thiab lwm yam yog siab dua li ntawm cov cheeb tsam tsim kho hauv Tebchaws Europe thiab Tebchaws Meskas.
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, roj hnyav (roj seem) hydrogenation, alkylation (superposition), reforming, thiab lwm yam, thiab qhov kev thov catalyst sib xws kuj tseem yuav nce ntxiv.
Txawm li cas los xij, vim muaj ntau lub voj voog siv ntawm ntau yam catalysts refining roj, qhov ntau ntawm cov catalysts refining roj tsis tuaj yeem nce nrog kev nthuav dav ntawm lub peev xwm. Raws li cov ntaub ntawv muag khoom hauv khw, qhov muag khoom feem ntau yog hydrogenation catalysts (hydrotreating thiab hydrocracking, suav txog 46% ntawm tag nrho), ua raws li FCC catalysts (40%), ua raws li reforming catalysts (8%), alkylation catalysts (5%) thiab lwm yam (1%).
