摘要
生物气是在特定条件下微生物作用于有机物生成的。研究认为,在甲烷生成菌的作用下,可通过CO_2+H_2和从有机基质中形成CH_4。生物气的组成一般以CH_4为主,常含数量不等的CO_2和N_2,C_2^+重烃含量甚微,C_1/C_(1～5)一般大于0.950,δ^(13)C_1一般小于-55‰。
Biogenetic gases are generated when bacteria acts upon the organic matters in the specific condi-tions. It is considered according to the research that by the action of methanobacteria the CH_4 may be formed by CO_2+H_2 and from organic matrix. Generally, the composition of biogenetic gases is mainly CH_4, always containing various amount of CO_2 and N_2 as well as little heavy hydrocarbon gas ((C_2)^+), C_1/C_(1~5>0. 950, δ~13C<-55‰.
