Catalysts thiab cov txheej txheem Txawm hais tias tsis siv tau, ruthenium disulfide zoo nkaus li yog ib qho tseem ceeb tshaj plaws catalyst, tab sis binary ua ke ntawm cob alt thiab molybdenum kuj tseem muaj zog heev. Ib cag los ntawm cov txheej txheem cob alt-hloov MoS 2 catalyst, nickel thiab tungsten kuj siv, nyob ntawm seb qhov khoom noj.
Lub reactor twg yog siv rau hydrodesulfurization?
Txhawm rau kom muaj txiaj ntsig zoo thiab kev sib cuag ntawm peb theem, trickle-bed reactors (TBR) yog siv rau hauv cov chaw ua dej loj loj rau cov txheej txheem hydrodesulfurization. γ-Al2O3 yog qhov kev txhawb nqa ntau tshaj plaws ntawm HDS catalysts.
HDS catalyst yog dab tsi?
Hydrodesulfurization (HDS) lossis Hydrotreating yog catalytic chemical txheej txheem dav siv los tshem tawm cov tshuaj sulfur los ntawm cov khoom siv roj av ua kom zooxws li roj av lossis roj av, dav hlau, roj av, thiab roj. roj.
hydrodesulfurization siv rau dab tsi?
Hydrodesulphurization (HDS) yog cov txheej txheem catalytic feem ntau siv hauv Roj & Roj thiab Refining industries kom tshem tawm cov sulfur los ntawm cov nkev roj thiab cov khoom ua kom zoo, suav nrog roj av, dav hlau roj, diesel. roj, roj, thiab naphtha.
CoMo catalyst yog dab tsi?
Cov CoMo hydrogenation catalysts hloov lwm yam kab mob uas tseem tshuav tawm ntawm Claus seem mus rau H2S ua ntej nkag mus rau amine tail gas seem rau kev kho zaum kawg.

Dab tsi yog qhov catalyst siv hauv kev sib cuag?
a catalyst of vanadium(V) oxide, V 2 O. Qhov kub ntawm ib ncig ntawm 450 ° C (xaiv raws li qhov ntsuas kub tsis sib haum, muab cov txiaj ntsig zoo nrog tus nqi zoo ntawm cov tshuaj tiv thaiv) Vim li cas lub catalyst siv hauv kev sib cuag?
Tus catalyst twg yog siv hauv cov txheej txheem bergius?
Iron tseem yog cov khoom siv hlau uas xaiv vim yog tus nqi thiab qhov muaj nyob. Kev siv cov sulfur hauv cov tshuaj tiv thaiv kab mob ntawm cov txheej txheem Bergius tau pom tias muaj txiaj ntsig zoo rau kev ua kom muaj txiaj ntsig ntawm cov catalyst .
Vim li cas cov neeg siv khoom thiab cov khoom siv tau siv hauv c ++?
Lub hom phiaj ntawm kev siv getters thiab setters yog txhawm rau zais cov ntaub ntawv khaws cia thiab rov qab li casTxoj kev no, yog tias koj hloov tus cwj pwm, koj tsis tas yuav hloov tus lej. nyob rau hauv ib txhiab qhov chaw. Tab sis, yog tias koj tsis tas yuav hloov qhov kev siv, koj tau ua koj cov cai ntau dua thiab tau txais me ntsis los ntawm kev ua li ntawd .
Qhov twg hauv qab no yog siv los xyuas kom meej tias cov ntaub ntawv yog cov tsiaj ntawv?
Qhov twg hauv qab no yog siv los xyuas kom meej tias cov ntaub ntawv yog cov tsiaj ntawv? Nqe lus piav qhia - Siv qhov kev xaiv - c nrog cov khoom siv xaiv txhawm rau txheeb xyuas tias cov ntaub ntawv tau raug txheeb xyuas . Qhov twg hauv qab no yog siv rau decompressing cov ntaub ntawv?
Qhov twg ntawm cov catalyst hauv qab no yog siv rau syn-hydroxylation ntawm alkene?
Osmium catalyzed cov tshuaj tiv thaiv. Osmium tetroxide (OsO 4 ) yog cov oxidant nrov siv hauv dihydroxylation ntawm alkenes vim nws kev ntseeg tau thiab ua haujlwm nrog kev tsim cov syn-diols . YDab tsi yog Syn hydroxylation ntawm alkenes?
