Coke- qhov cub gas, los ntawm - cov khoom lag luam los ntawm kev lag luam coking, ua cov khoom noj muaj txiaj ntsig zoo rau cov tshuaj methanol synthesis, ammonia tsim, tsim hydrogen thiab lwm yam txheej txheem. Txawm li cas los xij, coke- qhov cub roj muaj cov txheej txheem nyuaj thiab muaj cov organosulfur impurities ntau heev. Cov sulfur compounds no muaj cov qauv tshuaj ruaj khov thiab tsis tuaj yeem raug tshem tawm los ntawm cov txheej txheem desulfurization. Yog tias tsis muaj kev tshem tawm cov kab mob organosulfur zoo, kev sib xyaw ua ke hauv qab thiab ua haujlwm -section catalysts yuav raug kev lom sai sai thiab tsis ua haujlwm, thaum corrosion ntawm cov cuab yeej thiab cov kav dej yuav ua rau hnyav dua. Vim muaj cov khoom noj khoom haus, coke- qhov cub roj muaj feem ntau ntawm CO thiab olefins, ua rau muaj kev ua haujlwm hnyav thiab ua rau muaj teeb meem loj rau hydrodesulfurization. Ntau tus neeg ua haujlwm yuav tsum xa cov txheej txheem ntxiv los tiv thaiv cov khoom tsis zoo - cuam tshuam, uas ua rau tag nrho cov nqi tsim khoom thiab kev khiav haujlwm.
Organosulfur hydroconversion thev naus laus zis tsim rau coke- qhov cub gas muaj ib txoj hauv kev rau kev ua kom huv si sib sib zog nqus ntawm cov khoom noj roj. Los ntawm cov tshuaj tiv thaiv catalytic hydrogenation, cov thev naus laus zis no hloov ntau yam organosulfur tebchaw hauv cov pa mus rau hauv cov khoom siv tau yooj yim tshem tau hydrogen sulfide (H₂S). Cov txheej txheem desulfurization tom qab ntawd tshem tawm cov kab mob sulfur los lav cov khoom noj uas tsim nyog - roj zoo. Txawm li cas los xij, coke- qhov cub roj yog qhov nyuaj uas CO, olefins thiab ntau tus sulfur- muaj cov tshuaj sib xyaw ua ke. Thaum lub sij hawm hydrogenation, sab kev tshwm sim xws li olefin polymerization thiab methanation tau nkag mus rau qhov chaw. Cov tshuaj tiv thaiv sab no tsis tsuas yog haus cov khoom noj muaj txiaj ntsig xwb, tab sis kuj ua rau coke deposition ntawm cov khoom siv hluav taws xob, ua rau lub neej ua haujlwm luv luv thiab ua rau kev ua haujlwm ruaj khov ntawm tag nrho chav huv huv.
Txhawm rau kom ua tiav qhov ruaj khov thiab ua haujlwm tau zoo tshem tawm organosulfur, catalysts yuav tsum tau ua kom zoo - yoog rau cov coke complex no - qhov cub gas feed. Ntawm ib sab, lawv yuav tsum xa cov kev ua haujlwm hydroconversion kom ua tau zoo ntawm ntau hom organosulfur tam sim no hauv lub cev. Ntawm qhov tod tes, coking robust-kuj yog yuav tsum tau los suppress sab kev cuam tshuam nrog rau olefin polymerization. Tsis tas li ntawd, cov khoom muaj txiaj ntsig zoo xws li lub zog compressive txaus thiab tus nqi qis qis yog qhov tseem ceeb los tiv thaiv cov pa roj- ntws yaig nyob rau hauv cov chaw lag luam thiab xyuas kom ntev - lub sijhawm cog kev lag luam tas mus li.
Qhov tshwj xeeb - lub hom phiajXH-2hydroconversion catalystrau coke- qhov cub gas, tsim los ntawmShandong Xunda TshuajKev lag luamGroup Co., Ltd., yog tsim los ntawm proprietary npaj txheej txheem. Optimized rau coke- qhov cub roj noj uas muaj cov pa roj carbon monoxide thiab olefins, nws muab kev ua tau zoo tshaj qhov sib piv coking- roj ua haujlwm cov ntaub ntawv thiab nthuav tawm lub peev xwm hloov tau zoo mus rau ntau yam organosulfur tebchaw hauv pub roj. Nws yog dav siv nyob rau hauv feedstock pretreatment rau tshuaj tej yaam num xws li coke- qhov cub- roj- mus rau -methanol, ammonia synthesis thiab hydrogen ntau lawm.
