Sake fasalin Carbon dioxide

Gyaran carbon dioxide (wanda kuma aka sani da busassun gyara)wata hanya ce ta samar da iskar gas (gaurayawan hydrogen da carbon monoxide) daga amsawar carbon dioxide tare da hydrocarbons kamar methane tare da taimakon abubuwan karafa masu daraja(yawanci Ni ko Ni alloys). Ana samar da iskar gas ta al'ada ta hanyar gyaran tururi ko iskar gas. Acikin 'yan shekarun nan, ƙarin damuwa game da gudummawar iskar gas ga ɗumamar duniya ya ƙara sha'awar maye gurbin tururi a matsayin mai amsawa da carbon dioxide.

Ana iya wakilta ra'ayin bushewar gyaran fuska ta hanyar:

Wani batu kuma game da gyaran busasshen yana kasancewa a cikin gaskiyar cewa yana aiki a yanayin da ke samar da ruwa. A sakamakon haka, wannan ruwa zai iya haifar da maras so mayar da martani ga CO₂ via da ruwa-gas motsi dauki. Don hana CO₂ daga samuwa, kuma saboda haka asarar CO2, ana iya sanya CO₂ akan calcium oxide. Sakamakon haka, tsarin yana samar da CO da H₂O kawai, yana haɓaka ingantaccen amfani da kayan abinci. Wannan tsari an fi sani da Super-bushe gyara.
