Isikhwebu sommbila kanye nesikhwebu sommbila kukhiqiza inqubo yoboya
Isifinyezo
Izinto eziqukethe i-Pentosan plant fiber (njengesikhwebu sommbila, amagobolondo amakinati, izimbotshana zembewu kakotini, izimbotshana zerayisi, i-sawdust, ukhuni lukakotini) zizofakwa i-hydrolysis ibe i-pentose ngokushelela kwezinga lokushisa elithile kanye ne-catalyst, ama-Pentose ashiya ama-molecule amathathu amanzi ukuze akhe i-furfural.
Isikhwebu sommbila sisetshenziswa izinto ngokuvamile, futhi ngemva kochungechunge lwenqubo ehlanganisa Ukuhlanzwa, ukuchotshozwa, nge-acid hydrolysis, i-mash distillation, i-neutralization, i-dewatering, ukucwenga uthole i-furfural efanelekayo ekugcineni.
"Imfucuza" izothunyelwa ekushisweni kwe-boiler, umlotha ungasetshenziswa njengento egcwele ingqalasizinda noma i-organic.
Okwesithathu, ishadi lokugeleza kwenqubo:
Imvelo yamakhemikhali
Ngenxa yokuthi i-furfural inamaqembu asebenzayo e-aldehyde ne-dienyl ether, i-furfural inezakhiwo ze-aldehydes, i-ethers, i-dienes nezinye izinhlanganisela, ikakhulukazi ezifana ne-benzaldehyde. Ngaphansi kwezimo ezithile, i-furfural ingabhekana nokulandelayo kwamakhemikhali:
I-Furfural i-oxidized ukuze ikhiqize i-maleic acid, i-maleic anhydride, i-furoic acid, ne-furanic acid.
Esigabeni segesi, i-furfural ifakwa i-oxid nge-catalyst ukukhiqiza i-anhydrous malic acid.
I-Furfural hydrogenation ingakhiqiza i-furfuryl alcohol, i-tetrahydrofurfuryl alcohol, i-methyl furan, i-methyl tetrahydrofuran.
I-Furan ingenziwa ngesitimu esinefurfural kanye nesitimu samanzi ngemuva kokukhishwa kwe-carburization nge-catalyst efanele.
I-Furfural ibhekana nokusabela kwe-Conicaro ngaphansi kwesenzo se-alkali eqinile ukukhiqiza i-furfuryl alcohol ne-sodium furoate.
I-Furfural ingabhekana nokusabela kwe-Boqin ngaphansi kwesenzo se-fatty acid usawoti noma isisekelo se-organic futhi ifinyele nge-acid anhydride ukuze yakhe i-furan acrylic acid.
I-Furfural ihlanganiswe ne-phenolic compounds ukukhiqiza inhlaka ye-thermoplastic; ihlanganiswe ne-urea ne-melamine ukwenza ipulasitiki; futhi ijiya nge-acetone ukwenza i-furfurone resin.
Ukusetshenziswa kommbila
1. Ingasetshenziselwa ukukhipha izinsimbi ezisindayo emanzini angcolile, futhi ingasetshenziswa ukuvimbela amashidi ensimbi amancane ashisayo ukuthi anganamathelani.
2. Ingasetshenziswa ekukhiqizeni amakhadibhodi, ibhodi likasimende kanye nezitini zikasimende, futhi ingasetshenziswa njengokugcwalisa iglue noma ukunamathisela.
3. Ingasetshenziswa njenge-feed premix, i-methionine, i-lysine, i-lysine protein powder, i-betaine, amalungiselelo esikhunta ahlukahlukene, ama-antifungal agents, amavithamini, ama-phospholipids, i-phytase, ama-flavoring agents kanye ne-madurin, ukuphepha I-enzyme evamile ye-choline chloride, njll, izithasiselo zezidakamizwa zezilwane. , abathwali bokudla okunomsoco, bangangena esikhundleni sempushana yesibili, futhi futhi ingenye yezinto zokusetshenziswa eziyinhloko zokuvutshelwa kwebhayoloji. imikhiqizo.
4. Isetshenziselwa ukucubungula i-furfural ne-xylitol.
Imikhiqizo ehlobene

Ukubhekana nenqubo entsha yokulahlwa kwemfucumfucu ...
Ilungelo lobunikazi lokusungulwa likazwelonke Izici kanye nendlela yokwelapha amanzi angcolile angenaboya: Ane-asidi eqinile. Amanzi angcolile angaphansi aqukethe i-acetic acid engu-1.2% ~ 2.5%, eyi-turbid, khaki, transmittance light <60%. Ngaphezu kwamanzi ne-acetic acid, futhi iqukethe ngokwedlulele Inani elincane le-furfural, amanye ama-asidi e-organic trace, ama-ketone, njll. I-COD emanzini angcolile icishe ibe ngu-15000～20000mg/L...

Inqubo yokukhiqiza i-hydrogen peroxide
Inqubo yokukhiqiza i-hydrogen peroxide Ifomula yamakhemikhali ye-hydrogen peroxide yi-H2O2, eyaziwa kakhulu ngokuthi i-hydrogen peroxide. Ukubukeka kuwuketshezi olungenambala obala, luyi-oxidant enamandla, isixazululo saso esinamanzi silungele ukukhishwa kwamagciwane esilonda sezokwelapha kanye nokubulala amagciwane emvelo kanye nokubulala amagciwane ekudleni. Ngaphansi kwezimo ezijwayelekile, izobola ibe amanzi nomoya-mpilo, kodwa igundane lokubola...
