Catalyst txaj ua haujlwm tseem ceeb ntawm cov tshuaj tiv thaiv kab mob. Kev xaiv ntawm txaj hom ncaj qha cuam tshuam rau huab hwm coj thiab kev hloov hluav taws xob, kev ua haujlwm catalyst thiab kev ruaj ntseg tag nrho. Nws yuav tsum tau txiav txim raws li cov tshuaj tiv thaiv siab, kub, pub zog thiab txheej txheem load. Tsau txaj, txaj fluidized thiab slurry txaj yog peb hom loj siv dav hauv kev lag luam, txhua tus muaj cov yam ntxwv sib txawv thiab siv tau rau kev ua haujlwm.
Covtsau txajyog hom feem ntau tau txais kev pom zoo hauv kev lag luam tshuaj lom neeg thiab kev tiv thaiv ib puag ncig. Catalyst hais yog statically loaded nyob rau hauv lub reactor, thiab txau ntws los ntawm lub txaj nyob rau hauv plug flow qauv. Nws xa tawm txawm tias roj faib thiab tswj cov khoom siv nyob hauv lub sijhawm. Nrog rau qhov tsis tshua muaj catalyst attrition, lub txaj tswj lub suab ntawm cov qauv kev ntseeg siab thiab ruaj khov catalytic kev ua haujlwm thaum lub sijhawm ua haujlwm ntev -. Nws yog qhov zoo rau kev tsim khoom tas mus li nyob rau hauv nruab nrab thiab siab siab nrog me me kub thiab siab hloov pauv, thiab dav siv hauv hydrofining, flue gas denitrification, organic sulfur conversion thiab lwm yam txheej txheem. Nws cov teeb meem tseem ceeb suav nrog kev hloov pauv huab hwm coj tsawg thiab muaj kev cuam tshuam rau coking thiab blockage, uas yuav tsum tau kaw ib ntus rau catalyst regeneration lossis hloov.
Hauv ibfluidized txaj, siab -ntaus roj ntws tshem tawm cov khoom siv hluav taws xob los tsim cov roj homogeneous- cov khoom sib tov. Nws ua tiav cov huab hwm coj zoo heev thiab kev hloov hluav taws xob nrog qhov sib txawv ntawm qhov kub thiab txias ntawm lub txaj, kom tsis txhob muaj cua sov hauv zos. Hom no yog qhov zoo tagnrho rau cov tshuaj tiv thaiv exothermic heev thiab loj - muaj peev xwm ntev - voj voog ntau lawm, vim catalysts tuaj yeem thauj khoom, tshem tawm thiab rov tsim dua hauv online. Nws yog tsuas yog siv nyob rau hauv catalytic cracking thiab ib nrab oxidation txheej txheem. Txawm li cas los xij, hnyav catalyst abrasion thiab pulverization yuam kev nruj me ntsis ntawm catalyst hnav tsis kam. Cov ntaub ntawv rov qab- sib xyaw kuj tseem tuaj yeem tshwm sim thiab cuam tshuam cov kev xaiv xaiv.
Covslurry txajyog ib yam peb-theem reactor uas muaj roj, kua, thiab cov theem khoom. Ultrafine cov khoom catalyst hais raug tshem tawm hauv cov kua inert nruab nrab los tsim cov slurry ntws. Cov tshuaj tiv thaiv kab mob tau nkag mus rau hauv cov txheej slurry ntawm bubbling, ua kom muaj kev sib cuag tsis tu ncua ntawm cov pa roj, kua, thiab cov theem khoom rau cov tshuaj tiv thaiv catalytic. Cov kab ke no muaj qhov hloov pauv huab cua tsis tshua muaj zog thiab ruaj khov qhov kub thiab txias, ua rau nws haum rau qis - siab, mob me me. Nws yog feem ntau siv rau hauv cov txheej txheem xws li methanol synthesis thiab feem ntau muab qis dua tag nrho kev siv zog siv.
