Xyuas kom tseeb tias xa cov kev pabcuam zoo tshaj plaws, qhov zoo tshaj plaws, Kev xa khoom sai.
Kev txaus siab rau cov neeg siv khoom yog peb lub hom phiaj tseem ceeb. Peb tuav txoj kev ua haujlwm zoo, zoo, kev ntseeg siab thiab kev pabcuam tas mus li, Peb tau ua raws li lub hauv paus ntsiab lus ntawm kev lag luam "Zoo Ua Ntej, Hwm Cov Ntawv Cog Lus thiab Sawv Los Ntawm Lub Koob Npe, muab cov khoom lag luam thiab kev pabcuam zoo rau cov neeg siv khoom." Cov phooj ywg hauv tsev thiab txawv teb chaws zoo siab txais tos los tsim kev sib raug zoo ua lag luam nrog peb mus ib txhis.

Cov Lus Nug Feem Ntau

Xav tau kev pab? Nco ntsoov mus saib peb cov rooj sib tham txhawb nqa kom tau cov lus teb rau koj cov lus nug!

Peb puas tuaj yeem luam peb lub logo rau ntawm cov khoom?

Tau kawg, peb ua tau. Tsuas yog xa koj lub logo tsim rau peb.

Koj puas txais cov xaj me me?

Yog. Yog tias koj yog ib lub khw muag khoom me me lossis pib ua lag luam, peb yeej txaus siab loj hlob nrog koj. Thiab peb tab tom nrhiav rau pem hauv ntej kom ua haujlwm nrog koj rau kev sib raug zoo mus sij hawm ntev.

Tus nqi li cas? Koj puas ua tau kom pheej yig dua?

Peb yeej ib txwm xav txog qhov zoo ntawm cov neeg siv khoom ua qhov tseem ceeb tshaj plaws. Tus nqi tuaj yeem sib tham tau raws li ntau yam xwm txheej, peb paub tseeb tias koj yuav tau txais tus nqi sib tw tshaj plaws.

Koj puas muab cov qauv dawb?

Zoo siab uas koj sau tau cov kev tshuaj xyuas zoo rau peb yog tias koj nyiam peb cov khoom thiab kev pabcuam, peb yuav muab qee cov qauv dawb rau koj ntawm koj qhov kev txiav txim tom ntej.

Koj puas xa tau raws sijhawm?

Tau kawg! peb tshwj xeeb hauv kab no tau ntau xyoo, ntau tus neeg siv khoom ua ib daim ntawv cog lus nrog kuv vim peb tuaj yeem xa cov khoom raws sijhawm thiab khaws cov khoom zoo tshaj plaws!

Kuv puas tuaj yeem mus xyuas koj lub tuam txhab thiab lub Hoobkas hauv Suav teb?

Tseeb. Koj zoo siab tos txais koj tuaj xyuas peb lub tuam txhab hauv Zibo, Suav teb. (1.5H tsav tsheb los ntawm Jinan)

Kuv tuaj yeem tso qhov kev txiav txim li cas?

Koj tsuas yog xa peb cov lus nug rau ib tus neeg sawv cev muag khoom kom tau txais cov ntaub ntawv qhia txog kev txiav txim, thiab peb yuav piav qhia txog cov txheej txheem ntxaws ntxaws. Lub koom haum Fujian ntawm Cov Qauv ntawm Cov Khoom, Suav Academy of Sciences, tau ua kev tshawb fawb txog qhov sib piv ntawm cov khoom siv raw thiab ntau yam qhov chaw ceev ntawm catalytic synthesis ntawm dimethyl oxalate hauv kev tshawb fawb ntawm cov catalysts rau lub atmospheric pressure catalytic coupling ntawm CO rau oxalic acid, thiab xaiv cov xwm txheej tshuaj tiv thaiv tsim nyog. Lub Pd zoo dua (2.0%) / α-Al₂O₃ catalyst tau txais qhov chaw-lub sijhawm tso zis ntawm 999 g / L · h nyob rau hauv cov xwm txheej ntawm atmospheric pressure, 140 ° C, CO / CH₃ONO = 1.5, thiab qhov chaw ceev ntawm 3000 / h. Lub koom haum tau koom tes nrog Fujian Petrochemical Design Institute thiab Fujian Nanqing Ammonia Plant los ua qhov kev sim 100 t / a pilot ntawm kev rov qab CO los ntawm kev txhuam tooj liab ammonia, atmospheric pressure catalytic synthesis ntawm dimethyl oxalate, thiab hydrolysis rau oxalic acid.
Piv nrog rau txoj kev ua kua-theem, txoj kev no muaj kev xaiv siab, cov txheej txheem yooj yim, cov khoom ntshiab siab, thiab tus nqi tsim khoom qis. Nws tuaj yeem siv cov roj av lossis cov thee ua cov khoom siv raw, thiab tseem tuaj yeem siv cov pa roj carbon monoxide rov qab los ntawm ammonia tooj liab scrubbing lossis cov cua sov daj phosphorus, lub cub tawg, thiab cov pa roj converter tail ua cov pa roj carbon monoxide. Tib lub sijhawm, nws tuaj yeem muab cov khoom siv raw pheej yig rau kev tsim cov ethylene glycol thiab kev sib koom ua ke nrog oxalate ester ua ib qho nruab nrab.
