Raws li lub koom haum Fraunhofer rau kev sib tham ntawm engineering thiab biotechnology nyob hauv lub teb chaws Yelemees, ib hom tshiab ntoo qhuav tshuab tsim los ntawm eB-funded SteamBio project yuav txo qhov nqi ntawm kev thauj biomass.The technology kuj ua cov ntaub ntawv uas siv tshuaj lom neeg kev lag luam. Tus txheej txheem yog tam sim no raug soj ntsuam ntawm tus taw kev ntsuas.
Cov ntaub ntawv tso tawm los ntawm fraunhofer IGB lub koom haum piav tias hav zoov pov tseg thiab lwm yam tsis zoo ntoo yog hauv av rau ib daim, ib qho tseem ceeb raw khoom rau kev lag luam ntoo ua ke. Cov chips tseem siv tau ua roj rau thermal fais fab nroj tsuag thiab ntoo nti cua sov tshuab.Txawm , cov dej kub ntawm cov ntoo tuaj yeem tsim teeb meem.Qhov tsis zoo, dej nce qhov nyhav ntawm cov ntoo chips, ua rau lawv nyuaj rau kev thauj mus. Fraunhofer IGB kuj tau sau tseg tias nws tsis yooj yim los khaws cov khoom ntub thiab hais tias ntoo chips tsis muaj kev tiv thaiv los nag rot sai sai.
Chav SteamBio aims kom kov tau cov teebmeem no los ntawm kev ci ntsa iab.Thaum dhau los Fraunhofer IGB, 10 lwm tus neeg koom tes los ntawm plaub lub tebchaws hauv Tebchaws Europe tau koom hauv ChavBioBio project.
Lub koom haum Fraunhofer lub koom haum Fraunhofer IGB thiab Tus Thawj Ua Haujlwm Chav Ua Haujlwm Siegfried Egner tau piav qhia tias cov tshuab uas tsis koom rau hauv cov cua kub cua sov hauv chaw ua haujlwm. "Biomass muaj peb yam tseem ceeb - cellulose, lignin thiab hemicellulose, thiab qhov kev ua tiav tshem tawm qhov hemicellulose, "nws hais.Thaum qhov tshwm sim, biomass qhov hnyav txo, thiab nws qhov kev kub yog tsim kho kev txhim kho.Qhov txheej txheem kuj ua rau cov khoom siv tsis muaj dej.Thiab tas, ntoo chips yuav yooj yim hauv av ua rau siab heev hmoov los yog compressed ua cov hais.
Txawm hais tias Terrefaction tsis yog ib qho tshiab rau hauv nws txoj cai, hais tias Bruno Scherer, ib tug engineer project ntawm Fraunhofer IGB, SteamBio SIV lub tshuab drying tsim los ntawm Fraunhofer IGB rau kub ntawm 200 thiab 250 degrees Celsius.Qhov cim tshwj xeeb ntawm cov tshuab no yog Cov tshuaj tsw qab muaj nyob rau hauv biomass thiab cov khoom ua pa thaum lub caij ziab khaub zaws hauv cov chav kho mob thiab lawv tus kheej ua cov txheej txheem tawm xov xwm. "Ua lwm yam lus, peb siv lub qhov cub superheated," Scherer hais hauv ib nqe lus.
Raws li Fraunhofer IGB, qhov kub siab siv nyob rau hauv tus txheej txheem qhuav biomass, ua low-boiling organic compounds nrov heev.Qhov cellulose thiab lignin nyob twj ywm khoom, cov khoom tsis haum rau nkag mus rau cov pa phoj.Yuav condensers yog siv los ntes cov khoom siv gaseous thiab rov ua dua kua.
Ib qho chaw cog qoob loo yog nyob rau hauv Spain, siv ntoo thuv, ntoo qhib, beech, vineyard pruning thiab pov tseg los ntawm txiv roj roj.
