Enwere ike kewaa usoro nhazi nke gas biomass gaa na gasification biomass na pyrolysis. gasification biomass na-ezo aka na usoro mmepụta gas n'okpuru oke okpomọkụ (na-abụkarị 1000 ℃), ebe a na-ewebata ikuku, oxygen, ma ọ bụ uzuoku mmiri kwesịrị ekwesị n'ime gasifier iji nweta mmeghachi omume okpomọkụ nke biomass. pyrolysis biomass bụ usoro mmepụta gas n'okpuru ọnọdụ anaerobic ma ọ bụ anaerobic dị elu, dịka akọwara na ngalaba gasification na pyrolysis. N'okpuru ọrụ okpomọkụ, biomass nwere nnukwu molekul na-agbaze iji mepụta obere gas molekul, dị ka hydrogen, methane, ethane, wdg. A na-emepụta carbon monoxide site na mmeghachi omume okpomọkụ dị elu nke gas mmiri na carbon, a na-emepụtakwa ihe ndị ọzọ site na mmebi okpomọkụ.
N'ihi mmepụta ya dị elu, gas ahụ na-ebu obere okpomọkụ ma nwee ọtụtụ hydrogen na carbon monoxide, agwakọtara ya na mmiri, mmanụ na-agbanwe agbanwe, na uzuzu.

Ọ bụrụ na e jiri gasification biomass ma ọ bụ pyrolysis rụọ ọrụ nke ọma, gas biomass a na-emepụta bụ mmanụ ọkụ a na-apụghị ịcha nke na-abụghị naanị mmeghari ohuru, kamakwa ọ na-emezu ebumnuche nke ihicha nsị anụ ụlọ na ihe mkpofu. Gas biomass na-enyekwa ndị ọrụ ugbo ụzọ ọhụrụ isi enweta ego, na-ebelata ọnụ ahịa ijikwa nsị anụ ụlọ. Ọ bụrụ na ejiri ihe ọkụkụ ike mee ihe dị ka nri, ha ga-enwe ike dị elu karịa bioethanol na biodiesel.
N'eziokwu, gas biomass nwekwara mmetụta ka mma n'ibelata mwepụta gas na-ekpo ọkụ n'ime ụlọ. Ọ bụrụ na a hapụghị ya nke ọma, nsị ndị ahụ ga-ewepụta methane nwayọ nwayọ n'ime ikuku n'oge usoro mmebi ahụ. Ọ bụrụ na a gbanwee methane ka ọ bụrụ mmanụ site na mgbanwe nke gas biomass, ọ ga-emesịa wepụta naanị carbon dioxide, nke na-ebelata mmetụta nke ụlọ okpomọkụ.
Na mgbakwunye na ibelata ikuku na-ekupụ, gas biomass nwere ọtụtụ ojiji. Na mgbakwunye na ikpo ọkụ na isi nri n'ụlọ, enwere ike ịsacha methane ma gbanye ya n'ime netwọk ọkpọkọ gas eke maka ojiji yana gas eke sitere na isi mmalite dị n'okpuru ala; Na mgbakwunye, inye ihe eji arụ ọrụ maka ụgbọ ala gas eke bụkwa ụzọ dị mma iji ha. Ma e jiri ya tụnyere mmanụ ethanol na mmanụ dizel hà nhata, tọn gas biomass ọ bụla nwere ike ịkwado ụgbọ ala ịgba ọsọ karịa. Teknụzụ a nke nri anaerobic iji mepụta biogas dị irè maka nha niile site na ndị ọrụ ugbo nwere ọtụtụ tọn ihe eji arụ ọrụ ruo na nnukwu ụlọ ọrụ mmepụta ihe nwere ọtụtụ puku tọn ihe eji arụ ọrụ.
Isi ihe dị na gas sitere n'okike bụ methane. Ụlọ ọrụ anyị nwere ike inye. ndị na-emepụta gas sitere n'okike nwere ike otu nkeji nke 100KW, 150KW, 250KW, 300KW na ike nkeji emekọrịtara nke 500KW ~ 16MW. Igwe na-enye ọkụ gasJiri gas eke ma ọ bụ gas ndị na-emerụ ahụ mee ihe nke ọma dị ka mmanụ ọkụ, na-eme ka ihe mkpofu bụrụ akụ, ọrụ dị mma ma dịkwa mfe, arụmọrụ dị elu, mmetọ ikuku dị ala, ma dabara adaba maka njikọta okpomọkụ na ọkụ eletrik (Genestị CHP).
