Cov txheej txheem CCR, tseem hu ua Continuous Catalytic Reforming, yog cov txheej txheem tseem ceeb hauv kev kho cov roj av. Nws suav nrog kev hloov pauv ntawm low-octane naphtha rau hauv high-octane roj av sib xyaw. Cov txheej txheem hloov kho CCR yog ua los ntawm kev siv tshwj xeeb catalysts thiab reactors, xws li PR-100 thiab PR-100A, kom ua tiav cov tshuaj xav tau thiab cov khoom zoo.
Txoj kev hloov kho CCR yog ib kauj ruam tseem ceeb hauv kev tsim cov roj av zoo. Nws suav nrog kev hloov pauv ntawm cov saw hlau ncaj nraim rau hauv cov saw hlau txuas hydrocarbons, uas ua rau kom nce qib octane ntawm cov roj av. Qhov no yog qhov tseem ceeb rau kev ua kom tau raws li cov kev xav tau nruj rau cov roj av zoo thiab kev ua haujlwm zoo.
CovPIB-100thiab PR-100A yog cov catalysts uas tau tsim tshwj xeeb rau kev siv nyob rau hauvCCR txheej txheem. Cov catalysts no yog cov nquag nquag thiab xaiv, tso cai rau kev hloov pauv zoo ntawm naphtha rau hauv cov khoom siv roj av siab-octane. Lawv kuj tau tsim kom muaj kev ruaj ntseg zoo thiab ua haujlwm tsis zoo, ua kom lub neej ntev catalyst thiab ua haujlwm zoo ib yam.
Cov txheej txheem CCR pib nrog kev kho ua ntej ntawm naphtha feedstock kom tshem tawm cov impurities thiab sulfur compounds. Cov tshuaj naphtha ua ntej tau muab tso rau hauv CCR reactor, qhov chaw uas nws tau ntsib nrog PR-100 lossisPR-100A catalyst. Cov catalyst txhawb cov kev xav tau tshuaj lom neeg, xws li dehydrogenation, isomerization, thiab aromatization, uas ua rau muaj cov khoom siv roj av siab-octane.
Cov txheej txheem CCR ua haujlwm ntawm qhov kub thiab txias los pab txhawb cov tshuaj lom neeg xav tau. Lub reactor tsim thiab kev khiav hauj lwm tej yam kev mob yog ua tib zoo optimize maximize lub hloov dua siab tshiab ntawm naphtha mus rau hauv high-octane roj av Cheebtsam thaum ua kom lub stability thiab lub neej ntev ntawm lub catalyst.
Cov txheej txheem CCR yog kev ua haujlwm tas mus li, nrog cov catalyst tau rov tsim dua tshiab hauv qhov chaw kom tswj tau nws cov haujlwm thiab kev xaiv. Cov txheej txheem rov tsim dua tshiab no suav nrog kev tshem tawm carbonaceous deposits thiab reactivation ntawm catalyst, cia nws mus txuas ntxiv txhawb cov kev xav tau zoo.
Zuag qhia tag nrho, cov txheej txheem hloov kho CCR, nrog rau kev sivcatalysts xws li PR-100thiab PR-100A, plays lub luag haujlwm tseem ceeb hauv kev tsim cov roj av zoo. Nws ua kom cov refiners kom tau raws li qhov nruj octane thiab cov kev xav tau zoo rau cov roj av, kom ntseeg tau tias cov khoom kawg ua tau raws li qhov kev xav tau ntawm cov tshuab niaj hnub no.
Hauv kev xaus, lubCCR txheej txheemyog ib qho tseem ceeb ntawm cov txheej txheem refining, thiab kev siv tshwj xeeb catalysts xws liPR-100 thiab PR-100ANws yog ib qho tseem ceeb rau kev ua tiav cov txiaj ntsig zoo thiab muaj txiaj ntsig ntawm kev hloov pauv ntawm naphtha rau hauv high-octane roj av blending Cheebtsam. Cov txheej txheem no tseem ceeb heev rau kev ua kom tau raws li qhov xav tau ntawm kev lag luam tsheb niaj hnub no thiab ua kom muaj cov roj av zoo rau cov neeg siv khoom thoob ntiaj teb.
