Three process routes of manufacturing synthetic oil from nature gas are methanol to gasoline process F-T synthesis process and synthetic gas to dimethyl ether process .

目前，以天然气为原料生产 合成油主要有经甲醇制 汽油、F-T合成和合成气制二甲醚燃料三条技术路线。

The methanol can be synthesised by coal or natural gas and the synthetic process is simple the technology is ripe and the efficiency of the energy is higher in comparison with that of the gasoline .

甲醇可由煤或天然气合成，目前已达到用1.5t标准 燃料合成1t甲醇的水平， 合成工序比合成 汽油简单，工艺成熟，能量效率高。

The alternative fuels to petroleum include product oil from direct coal liquefaction synthetic oil from indirect coal liquefaction methanol ethanol gasoline ethanol diesel oil methanol gasoline biological diesel oil and natural gas hydrate .

石油的替代燃料有煤直接液化成品油、煤间接液化 合成油、甲醇、乙醇 汽油、乙醇柴油、甲醇汽油、生物柴油和天然气水合物。
