Gore rapfuura takanyora nezve eFuel, iyo mafuta ekugadzira kubva kuBosch, inokwanisa kutsiva mafuta epetroleum atiri kushandisa parizvino. Kuti tivagadzire, tinoda zvinhu zviviri: H2 (Hydrogen) uye CO2 (carbon dioxide) - nechokupedzisira chinongedzo chiri kuwanikwa nekuchidzokorora kuburikidza nemaindasitiri maitiro kana kutorwa zvakananga kubva kumhepo pachayo uchishandisa mafirita.
Zvakanakira zviri pachena. Mafuta anova seizvi carbon neutral - izvo zvinogadzirwa mukupisa kwayo zvaizodzoserwa zvakare kuita mamwe mafuta -; hapana hurongwa hutsva hwekugovera hunodiwa - huripo hunoshandiswa; uye chero motokari, itsva kana yekare, inogona kushandisa mafuta aya, sezvo zvivakwa zvichichengetwa maererano nemafuta aripo.
Saka dambudziko nderei?
Kunyangwe paine zvirongwa zvekutyaira zviri kuitika, nerutsigiro rwenyika muGermany neNorway, mitengo yacho yakakwira zvakanyanya, izvo zvingangoderedzwa nekugadzirwa kwakawanda uye kudzikiswa kwemutengo wesimba rinogoneka.Nhanho yakakosha ikozvino yatorwa kune ramangwana kupararira kwemafuta ekugadzira. Kambani yeCanada, Carbon Engineering, yakazivisa kufambira mberi kwetekinoroji mukutora CO2, ichidzikisa zvakanyanya mutengo wekushanda kwese. CO2 matekinoroji ekutora atovepo, asi zvinoenderana neCarbon Engineering maitiro avo anokwanisika kutenga, kuderedza mari kubva pamadhora mazana matanhatu patani kusvika pamadhora zana kusvika pamadhora zana nemakumi mashanu patani yeCO2 yakabatwa.
Zvinoshanda sei
Iyo CO2 iripo mumhepo inosvetwa mukati nevaunganidzi vakakura vanofanana neshongwe dzinotonhorera, mweya unosangana nemushonga wemvura hydroxide, unokwanisa kuchengetedza kabhoni dhaokisaidhi, uchishandura kuita mvura ine carbonate solution, muitiro unoitika mumhepo contactor. . Isu tinobva taenda kune "pellet reactor", iyo inogadzirisa zviduku zviduku (mabhora ezvinyorwa) zve calcium carbonate kubva kune aqueous carbonate solution.
Mushure mekuoma, calcium carbonate inogadziriswa kuburikidza ne calciner inoipisa kusvika pakuora mu CO2 uye yakasara calcium oxide (iyo yekupedzisira inodzorerwa uye inoshandiswa zvakare mu "pellet reactor").
Iyo CO2 inowanikwa inokwanisa kupomba pasi pevhu, kuiteya, kana kuishandisa kugadzira mafuta ekugadzira. Maitiro eCarbon Engineering haana kunyanya kusiyana nematanho anowanikwa muindasitiri yemapepa nemapepa, saka iyi nhanho - padanho rezvigadzirwa zvemakemikari nemaitirwo - zvinoreva kuti pane mukana chaiwo wekukwirisa sisitimu nekuitanga kutengeserana.
Izvo chete nekuiswa kwemahombe-akakura ekutora mhepo, ari kunze kwemaguta uye pane isingarimeke ivhu, kuti mutengo we100 kusvika ku150 madhora patani yeCO2 yakatorwa, yakacheneswa uye kuchengetwa pa150 bar ingagoneka.
Kambani yeCanada yakagadzirwa muna 2009 uye ine pakati pevanoisa mari yavo Bill Gates uye yatova nediki diki yekuratidzira chirimwa muBritish Columbia, Canada, uye ikozvino iri kuedza kukwezva mari yekuvaka yekutanga kuratidzira unit pachiyero chekutengesa.
kubva kumhepo kuenda kuhuni
Sezvatakambotaura muBosch's eFuel, iyo CO2 yakatorwa kubva mumhepo yaizosanganiswa nehydrogen - inowanikwa kubva ku electrolysis yemvura, uchishandisa simba rezuva, iro mutengo unoramba uchidzikira - kugadzira mafuta emvura, sepeturu, dhiziri, kana kunyange. Jet- A, inoshandiswa mundege. Mafuta aya, sezvataurwa pamusoro apa, haana kwaakarerekera muCO2 emissions, uye, zvinotonyanya kukosha, haachashandisi crude.
Izvi zvinounza mamwe mabhenefiti, sezvo mafuta ekugadzira asina sarufa uye ane yakaderera particle values, achibvumira kupisa kwakachena, kwete chete kuderedza greenhouse gas emissions, asiwo kuderedza kusvibiswa kwemhepo.
