Furfural thiab pob kws cob ua cov txheej txheem furfural

Nqe lus piav qhia luv:

Cov uas muaj Pentosan cog cov khoom siv fiber ntau (zoo li Pob Kws cob, txiv laum huab xeeb, paj rwb noob hulls, txhuv nplej, sawdust, paj rwb ntoo) yuav hydrolysis rau hauv pentose nyob rau hauv kev nplij siab ntawm qee qhov kub thiab catalyst, Pentoses tawm ntawm peb dej molecules los ua furfural.

Ntsiab lus

Cov uas muaj Pentosan cog cov khoom siv fiber ntau (zoo li Pob Kws cob, txiv laum huab xeeb, paj rwb noob hulls, txhuv nplej, sawdust, paj rwb ntoo) yuav hydrolysis rau hauv pentose nyob rau hauv kev nplij siab ntawm qee qhov kub thiab catalyst, Pentoses tawm ntawm peb dej molecules los tsim furfural

Cov pob kws cob yog siv los ntawm cov ntaub ntawv feem ntau, thiab tom qab txheej txheem txheej txheem uas suav nrog Kev Ua Kom huv, sib tsoo, nrog kua qaub hydrolysis, mash distillation, neutralization, dewatering, refining tau txais kev tsim nyog furfural thaum kawg.

Cov "Khib Nyiab" yuav raug xa mus rau lub rhaub dej kub, cov hmoov tshauv tuaj yeem siv ua cov khoom ntim rau cov txheej txheem lossis cov organic

Thib peb, txheej txheem txheej txheem txheej txheem:

Furfural and corn cob produce furfural process1

Tshuaj lom neeg

Vim tias furfural muaj aldehyde thiab dienyl ether pab pawg ua haujlwm, furfural muaj cov yam ntxwv ntawm aldehydes, ethers, dienes thiab lwm yam sib xyaw, tshwj xeeb tshaj yog zoo ib yam li benzaldehyde. Hauv qee qhov xwm txheej, furfural tuaj yeem hla cov tshuaj lom hauv qab no:

Furfural yog oxidized los tsim cov tshuaj maleic acid, maleic anhydride, furoic acid, thiab furanic acid.
Hauv cov theem roj, furfural tau oxidized los ntawm cov catalyst los tsim cov anhydrous malic acid.
Furfural hydrogenation tuaj yeem tsim furfuryl cawv, tetrahydrofurfuryl cawv, methyl furan, methyl tetrahydrofuran.
Furan tuaj yeem ua los ntawm cov pa taws ua pa thiab dej ua kua tom qab decarburization nrog cov tshuaj tsim nyog.
Furfural hla Conicaro cov tshuaj tiv thaiv nyob rau hauv qhov kev txiav txim ntawm muaj zog alkali los tsim furfuryl cawv thiab sodium furoate.
Furfural tuaj yeem ua rau Boqin cov tshuaj tiv thaiv nyob rau hauv qhov ua ntawm fatty acid ntsev lossis organic puag thiab sib xyaw nrog cov kua qaub anhydride los tsim furan acrylic acid.
Furfural tau sib xyaw nrog cov tshuaj phenolic los tsim cov thermoplastic cob; nws yog condensed nrog urea thiab melamine los ua yas; thiab nws tau tso nrog acetone los ua cov tshuaj furfurone.

Corncob siv

1. Nws tuaj yeem siv los tshem tawm cov hlau hnyav los ntawm cov dej khib nyiab, thiab nws tuaj yeem siv los tiv thaiv cov hlau nyias nyias los ntawm kev sib koom ua ke.
2. Nws tuaj yeem siv rau hauv kev tsim cov ntawv los xij, lub rooj tsav tsheb hauv lub hauv paus thiab cov cement cib, thiab nws tuaj yeem siv los ua cov muab tshuaj txhuam rau kua nplaum lossis muab tshuaj txhuam.
3. Nws tuaj yeem siv los ua khoom noj ua ntej, methionine, lysine, lysine protein hmoov, betaine, ntau yam kev npaj pwm, tshuaj tua kab mob, vitamins, phospholipids, phytase, cov tshuaj tsw qab thiab madurin, kev nyab xeeb nquag enzyme choline chloride, thiab lwm yam. , cov nqa khoom noj khoom haus, tuaj yeem hloov hmoov thib ob, thiab tseem yog ib qho tseem ceeb ntawm cov khoom siv raw rau fermentation ntawm cov khoom siv lom.
4. Siv rau kev ua furfural thiab xylitol.
