Kuyaxatyiswa ukuba ungasibhalela uphononongo oluhle ukuba uyayithanda imveliso kunye nenkonzo yethu, siza kukunika iisampulu zasimahla kwi-odolo yakho elandelayo.

Ngaba uyakwazi ukunikezela ngexesha?

Ewe kona! Sikhetheke kakhulu kule ntambo kangangeminyaka emininzi, abathengi abaninzi benza isivumelwano nam kuba siyakwazi ukuhambisa iimpahla ngexesha kwaye sigcine iimpahla zisemgangathweni ophezulu!

Ndingandwendwela inkampani yakho kunye nomzi-mveliso eTshayina?

Ewe. Wamkelekile kakhulu ukutyelela inkampani yethu eZibo, eTshayina. (Iiyure ezili-1.5 ukusuka eJinan)

Ndingayifaka njani iodolo?

Ungasithumela nje umbuzo kuye nawuphi na ummeli wethu wentengiso ukuze ufumane ulwazi oluneenkcukacha zeodolo, kwaye siza kuchaza inkqubo yeenkcukacha. I-Fujian Institute of Structure of Matter, i-Chinese Academy of Sciences, yenze uphando malunga nomlinganiselo wezinto eziluhlaza kunye neemeko ezahlukeneyo zesantya sendawo kwi-catalytic synthesis ye-dimethyl oxalate kuphando lwee-catalysts zokudibanisa uxinzelelo lwe-atmospheric catalytic ye-CO kwi-oxalic acid, kwaye ikhethe iimeko ezifanelekileyo zokuphendula. I-catalyst ye-Pd (2.0%)/α-Al₂O₃ ephuculweyo ifumene isivuno sexesha lesithuba se-999 g/L·h phantsi kweemeko zoxinzelelo lwe-atmospheric, i-140 °C, i-CO/CH₃ONO=1.5, kunye nesantya sesithuba se-3000/h. Eli ziko lisebenzisane ne-Fujian Petrochemical Design Institute kunye ne-Fujian Nanqing Ammonia Plant ukwenza uvavanyo lwe-100 t/a lokuvavanya ukubuyisela i-CO kwi-synthetic ammonia copper scrubbing, i-atmospheric pressure catalytic synthesis ye-dimethyl oxalate, kunye ne-hydrolysis kwi-oxalic acid.
Xa kuthelekiswa nendlela yesigaba solwelo, le ndlela inokukhetha okuphezulu, inkqubo elula, ubumsulwa obuphezulu bemveliso, kunye neendleko eziphantsi zemveliso. Ingasebenzisa igesi yendalo okanye amalahle njengezinto eziluhlaza, kwaye ingasebenzisa ne-carbon monoxide efunyenwe kwi-ammonia copper scrubbing okanye kwi-yellow phosphorus furnace, kwi-blast furnace, nakwi-converter tail gas njengomthombo wegesi ye-carbon monoxide. Kwangaxeshanye, inokubonelela ngezinto eziluhlaza ezingabizi kakhulu zokuvelisa i-ethylene glycol kunye ne-united synthesis ene-oxalate ester njenge-intermediate.
