Ubuchwepheshe bokukhiqiza utshwala botshwala

Inkampani yethuibambisana ne-East China University of Science neTekhnoloji, futhi aqale amukele ukusabela okuqhubekayo ku-kettle kanye nenqubo eqhubekayo yokudambisa ukukhiqizwa kweUtshwala we-furfurl. Ukuqaphela ngokuphelele ukusabela ekushiseni okuphansi okushisa kanye nokusebenza okude okuzenzakalelayo, okwenza ikhwalithi ezinzile nezindleko zokukhiqiza ziphansi. Sineqoqo eliphelele lomkhiqizo wezinto zokwakha, futhi senze intuthuko enkulu kwinqubo nezinhlobo zomkhiqizo. Imikhiqizo ekhethekile eyenziwe uku-oda iyatholakala nangokwesicelo esivela kumakhasimende. Sinamaqembu ochwepheshe ajabulele idumela elihle embonini yokukhiqiza, ucwaningo kanye nensizakalo, akwazi ukuxazulula izinkinga zakho zokuphonsa ngesikhathi.

Ngo-1931, amakhemikhali aseMelika athola i-hydrogenation of furfural to furfuurry utshwala okokuqala nge-chromic acid njenge-cardrogenation ring kanye ne-Aldehyde Group, futhi ukukhethwa komkhiqizo kungathuthukiswa ngokushintsha izinga lokushisa nezimo zokuphendula ezi-catalytic. Ngokusho kwezimo ezihlukile zokuphendula, inqubo ye-furfural hydrogenation ku-furfuurry utshwala ingahlukaniswa ngezigaba zesigaba se-liquid kanye nendlela yesigaba segesi, esingahlukaniswa ngendlela ephezulu yokucindezela (9.8MPA) nendlela yengcindezelo ephakathi (5 ~ 8mpa).

i-gein ganal hydrogenation

I-Liquid Stage Hydrogenation ukumisa i-catalyst nge-furfiral ngo-180 ~ 210 ℃, ingcindezi ephakathi nendawo noma i-hydrogenation ephezulu, idivaysi ingumpetha ongenalutho. Ukuze unciphise umthwalo wokushisa, inani lokufakwa kwama-furfiral lalivame ukulawulwa futhi isikhathi sokuphendula (sikhulu kune-1h) sakhula isikhathi eside. Ngenxa ye-backmixing yezinto zokwakha, ukusabela kwe-hydrogenation akunakuhlala esigabeni sesizukulwane se-furfugrer wotshwala, futhi kungaqhubekela phambili nge-byproductfurfurfurfuran kanye ne-tetrahydrofurfurfuran kanye ne-tetrahydrofurfurfuran kanye ne-tetrahydrofurfurfuran notshwala ngokweqile, futhi kunzima ukubuyisa ukungcoliswa kwemfucuza, okulula kubangela ukungcoliswa kwe-chromium. Ngaphezu kwalokho, indlela yesigaba se-liquid idinga ukusebenza ngaphansi kwengcindezi, edinga izidingo zemishini ephezulu. Njengamanje, le ndlela isetshenziswa ikakhulukazi ezweni lethu. Ingcindezi yokuphendula ephezulu ingukushiyeka okuyinhloko kwendlela yesigaba se-liquid-siqu. Kodwa-ke, ukukhiqizwa kotshwala be-furfugrerl ngokusabela kwesigaba se-liquid ngaphansi kwengcindezi ephansi (1 ~ 1.3mpa) kubikwe eChina, futhi kutholwe isivuno esikhulu.

Njengenye yezinto zokwenziwa eziluhlaza zokuhlanganiswa kwe-organic, ingasetshenziselwa ukukhiqiza i-levilinic acid, furan resin enezakhiwo ezahlukahlukene, i-furfuryl alcohol-urcol-resin kanye ne-phenolic resin. Ukuphikiswa okubandayo kwamapulasitiki okwenziwe kuwo kungcono kunalokho kwe-buthanol ne-octanol esters. Kubuye kube yi-solves enhle yama-remins we-furan, ama-varnish, kanye nemibala, kanye nama-rocket fuel. Ngaphezu kwalokho, futhi isetshenziswa kwizicucu zokwenziwa, irabha, ama-pesticides kanye nezimboni ezitholile.
