原料气各物质的比例不同，可以制备不同碳氢比的合成气。

Different feed gas ratio could produce synthesis gas of different H/C radio.

材料的合成过程是这样：首先，他使高温碳氢混合气体和铁催化剂相互作用产生密集的碳纳米管群，然后再用聚合物充填碳纳米管间的空隙。

He created this composite by growing a forest of nanotubes using hot hydrocarbon gases and an iron catalyst, and then filling the space between the tubes with the polymer.

现在已有把二氧化碳变为合成气的工业生产，而且可以在同一个生产过程中继续把合成气转化为液态碳氢化学物。

Commercial processes are already available that use carbon dioxide to make a mixture called syngas, which can then be converted to liquid hydrocarbons in a process that can run continuously.
