Furfural uye chibage cob zvinogadzira furfural process
Summary
Iyo ine Pentosan chirimwa chefiber zvinhu (seChibage cob, mateko enzungu, mhodzi dzedonje, mazambiringa emupunga, sawdust, huni hwedonje) inozogadzira hydrolysis mupentose mukutsetseka kweimwe tembiricha uye inokonzeresa, Pentoses inosiya mamorekuru matatu emvura kuti aite furfural.
Muguri wechibage unoshandiswa nemidziyo kazhinji, uye mushure mekutevedzana kwemaitiro anosanganisira Kucheneswa, kupwanya, neacid hydrolysis, mash distillation, neutralization, dewatering, kunatsa kuwana akakodzera furfural pakupedzisira.
Iyo "Waste" inotumirwa kune iyo boiler inopisa, madota anogona kushandiswa seakazadzwa zvinhu zvezvivakwa kana organic.
Chechitatu, iyo process flow chart:
Chemical nature
Nemhaka yokuti furfural ine aldehyde uye dienyl ether inoshanda mapoka, furfural ine maitiro ealdehydes, ethers, dienes uye mamwe maitiro, kunyanya akafanana nebenzaldehyde. Mune mamwe mamiriro ezvinhu, furfural inogona kuita zvinotevera kemikari kuita:
Furfural is oxidized kugadzira maleic acid, maleic anhydride, furoic acid, uye furanic acid.
Muchikamu chegasi, furfural inoiswa oxidized necatalyst kugadzira anhydrous malic acid.
Furfural hydrogenation inogona kugadzira furfuryl doro, tetrahydrofurfuryl doro, methyl furan, methyl tetrahydrofuran.
Furan inogona kugadzirwa kubva kune furfural chiutsi uye chiutsi chemvura mushure me decarburization ine yakakodzera catalyst.
Furfural inopinda Conicaro reaction pasi pechiito che alkali yakasimba kugadzira furfuryl doro uye sodium furoate.
Furfural inogona kusangana neBoqin reaction pasi pekuita kwemafuta acid munyu kana organic base uye condense ne acid anhydride kuita furan acrylic acid.
Furfural inogadziriswa ne phenolic compounds kuti ibudise thermoplastic resin; inoputirwa neurea uye melamine kuita plastiki; uye yakanyungudutswa neacetone kuita fufurone resin.
Corncob inoshandisa
1. Inogona kushandiswa kubvisa simbi inorema kubva mumvura yakasviba, uye inogona kushandiswa kudzivirira kupisa simbi matete mapepa kuti asanamatirana.
2. Inogona kushandiswa mukugadzirwa kwekadhibhodhi, simenti bhodhi uye simenti zvidhinha, uye inogona kushandiswa sekuzadza kweglue kana paste.
3. Inogona kushandiswa se feed premix, methionine, lysine, lysine protein powder, betaine, zvakasiyana-siyana kugadzirira mold, antifungal agents, mavitamini, phospholipids, phytase, flavouring agents uye madurin, kuchengetedza Common enzyme choline chloride, nezvimwewo, veterinary drug additives. , zvinovaka muviri zvinotakura, zvinogona kutsiva chechipiri hupfu, uye zvakare ndeimwe yemhando huru yekuvirisa yebiological. zvigadzirwa.
4. Inoshandiswa kugadzira furfural uye xylitol.

Kutarisana nemaitiro matsva emarara efurfural ...
National invention patent Maitiro uye nzira yekurapa ye furfural wastewater: Iine yakasimba acidity. Pasi pemvura yakasviba ine 1.2% ~ 2.5% acetic acid, iyo ine turbid, khaki, light transmittance <60%. Pamusoro pemvura uye acetic asidhi, ine zvakare yakanyanyisa Hunhu hushoma hwefurfural, mamwe ma organic acids, ketoni, nezvimwe. Iyo COD mumvura yetsvina inoita 15000～20000mg/L...

Nzira yekugadzira hydrogen peroxide
Kugadzirwa kweHydrogen peroxide Kemikari formula yehydrogen peroxide iH2O2, inowanzozivikanwa sehydrogen peroxide. Chitarisiko imvura inopenya isina ruvara, iine oxidant yakasimba, mhinduro yayo ine aqueous inokodzera kuuraya hutachiona hwemaronda ekurapa uye disinfection yezvakatipoteredza uye disinfection yechikafu. Mumamiriro ezvinhu akajairwa, inoora kuita mvura uye oksijeni, asi gonzo rekuora ...
