Cellulose ni PolySaccharide igizwe n'ibice byinshi bya glucose bifitanye isano na β - 1,4-Glycosic Bonds. Nibice nyamukuru byinkuta zamatero kandi itanga inkuta zamababi inkunga ikomeye yubaka nubuka bwiza. Kubera umupaka muremure wa selile hamwe na karina rinini, rifite umutekano kandi uhungabanywa.
(1) imitungo ya selile ningorane zo gushonga
Cellulose afite imitungo ikurikira ituma bigorana:
Ingabo zisanzwe: Urunigi rwa selile rufite imiterere ya lattice binyuze muri hydrogen bonds na van der waails.
Urwego rwo hejuru rwa Polymeye: Urwego rwa Polymeye (ni ukuvuga uburebure bw'umunyururu wa molekile) wa selile ni muremure, ubusanzwe kuva ku bihumbi magana bigera ku bihumbi bya glucose, byongera umutekano wa molekile.
Umuyoboro wa Hydrogen: Ingwate ya hydrogen irahari cyane hagati no mubikorwa bya selile, bikagora gusenywa no gushonga na leta rusange.
(2) Reagents ishonga selile
Kugeza ubu, reage zizwi zishobora gushonga neza selile zirimo ibyiciro bikurikira:
1. Amazi ya Ionic
Amazi ya Ionic ni amazi igizwe na kama na anoni kama cyangwa anoorganike, mubisanzwe hamwe no guhindagurika hasi, umutekano muremure no gukurikira cyane. Amazi amwe arashobora gushonga selile, kandi uburyo nyamukuru ni ugusenya amazu ya hydrogen hagati yiminyururu ya falegile. Ibintu bisanzwe bya Ioonic bishonga selile birimo:
1-Butyl-3-methimliimazolium chloride ([bmim] cl): Iyi ionic yamazi ya ionic irashonganya na selile isabana na hydrogen muri selige ibemera.
1-Enestyl-3-Methilimazolium ACetate ([EMIM] [AC]): Aya mazi ya ionic arashobora gushonga kwibanda cyane kuri selile ugereranije na selile ugereranije.
2. Amine Oxident Igisubizo
Amine Oxident igisubizo nkikibazo givanze cya dietinylamine (dea) na chloride yumuringa yitwa [II (II) -Umucyo wa II), nibwo buryo bukomeye bwo gushonga bushobora gusenya selile. Irasenya imiterere ya karuki binyuze kuri okiside na hydrogène ihuza, bigatuma urunigi rwa moleki woroshye rworoshye kandi rusakuza cyane.
3. Limium Chloride-Dimethylacetamide (Sisitemu ya Licl-DMAC)
Sicl-dmac (limium chruride-dimethylacetamide) sisitemu nimwe muburyo bwa kera bwo gushonga. Licl irashobora gushiraho amarushanwa ya hydrogen, bityo asenya imiyoboro ya hydrogen hagati ya molekile ya selile, mugihe dmac nkibintu bishobora gukorana neza numuryango wa selile.
4. Hydrochloric acide / zinc chloride igisubizo
Amashanyarazi ya hydrochloric / zinc chloride numuti wavumbuwe hakiri kare bishoboka ko yashonga selile. Irashobora gusezerera selile ikora ingaruka zihuza iminyururu ya zinc na selile, kandi aside hydrochloric isenya ingwate hagati ya molekile. Ariko, iki gisubizo ni urwenya cyane kubikoresho kandi bigarukira mubikorwa bifatika.
5. Fibrinolytic enzymes
Fibrinolytic Enzymes (nka selile) ishonga selile ya cataliza yanduye selile muri oligosaccharides ntoya na monosacrides. Ubu buryo bufite urwego runini mubice bya biodegrado na biomass bihinduka, nubwo inzira yo kutubaka idasenyuka ntabwo iseswa imiti, ariko igerwaho na biocatalyse.
(3) uburyo bwo gusenya kwa selile
Reagents zitandukanye zifite uburyo butandukanye bwo gushonga kwa Celilose, ariko muri rusange barashobora kwitirirwa uburyo bubiri bwingenzi:
Kurimbuka kw'iminyururu ya hydrogen: Kurimbura Amashanyarazi hagati yiminyururu ya selile ya selile binyuze mumarushanwa ya hydrogène cyangwa imikoranire ya ionic, kora gukemurwa.
MoleCular urunikiro ruruhura: Kongera ubwiherero bwa molekile ya selile no kugabanya inyamanswa za moleki zinyuze muburyo bwumubiri cyangwa imiti, kugirango bashongeshejwe.
(4) Gusaba bifatika byo gusenya kwa selile
Iseswa rya Cellulose rifite ibyifuzo byingenzi mubice byinshi:
Gutegura ibikomoka kuri selile: Nyuma yo gushonga kwa selile, birashobora guhindurwa shimishwa no gutegura abakoresha selile, exetuse esters nibindi bikomokaho, bikoreshwa cyane mubiryo, ubuvuzi, amatara nizindi nzego.
Ibikoresho bishingiye kuri selile: Gukoresha ibishishwa byashonze, NanofiBers, Membranes hamwe n'ibindi bikoresho birashobora gutegurwa. Ibi bikoresho bifite imitungo myiza na biocompat.
Ingufu za Biomass: mugusebya no gutesha agaciro kasheli, birashobora guhinduka isukari isekeje kugirango umusaruro wa bioful nka biothanol, bifasha kugera ku iterambere no gukoresha ingufu zishobora kongerwa no gukoresha ingufu zishobora kongerwa no gukoresha ingufu zishobora kongerwa.
Gusimbuka kwa Cellulose nigikorwa kitoroshye kirimo uburyo bwinshi bwa miti. Amazi ya Ionic, Amino Oxident Ibisubizo, Sisitemu ya Licl-Dmach, Ibisubizo bya Hydrochloric / Zinc Chlolsimes Buri mukozi afite uburyo bwihariye bwo gusebanya hamwe no gusaba. Hamwe ninyigisho yimbitse ya Mecsolution ya Cellulmes, bizera ko uburyo bunoze bunoze kandi bushingiye ku bidukikije buzatezwa imbere, butanga ibindi buryo bishoboka kugirango dukoreshe no guteza imbere selile.
