A second process, called thermochemical pyrolysis, USES high temperatures and pressures to convert cellulosic biomass into long hydrocarbon chains that are similar to gas, diesel or jet fuel.

第二种方法也被称作“反应炉裂解法”：利用高温和压力将纤维素生物质转换成长烃链，这种长烃链和汽油、柴油、喷气式发动机燃料相类似。

The thermochemical sulfate reduction (TSR) refers to the process of sulfate reaction with hydrocarbons, which is the important mechanism for generating natural gas with high content of H2S and CO2.

硫酸盐热化学还原反应(TSR)是指硫酸盐与烃类作用，将硫酸盐矿物还原生成h2s等酸性气体的过程，是高含h2s天然气形成的重要机制。
