Nrụgide nchekwa dị ala, dị mfe iji hụ na nchekwa
Nchekwa mmiri hydrogen na ndabere nke mkpuchi iji hụ na nkwụsi ike nke akpa ahụ, ọkwa nrụgide nke nchekwa kwa ụbọchị na njem ụgbọ ala dị ala (n'ozuzu ala karịa 1MPa), dị ala karịa ọkwa nrụgide nke nnukwu nrụgide gas na nchekwa hydrogen na njem njem, nke dị mfe iji hụ na nchekwa na usoro ọrụ kwa ụbọchị. Ejikọtara ya na njirimara nke nnukwu nchekwa nchekwa mmiri hydrogen dị arọ, n'ọdịnihu nnukwu nkwalite ike hydrogen, nchekwa mmiri hydrogen na njem (dị ka ọdụ hydrogenation mmiri mmiri) ga-enwe usoro ọrụ dị mma na mpaghara obodo nwere nnukwu njupụta ụlọ, ọnụ ọgụgụ buru ibu na ọnụ ala dị elu, na usoro dum ga-ekpuchi obere mpaghara, na-achọ obere ego ntinye ego mbụ na ụgwọ ọrụ.
 
Ịdị ọcha dị elu nke vaporization, izute ihe achọrọ nke ọnụ
