And some go for pure chemistry, breaking the cellulose down into a gaseous mixture of hydrogen and carbonmonoxide before building it back up into something more useful.
也有的是纯粹的化学，将纤维素分解成一种氢和碳的气体混合物，然后再将其合成更为有用的东西。

This releases a mixture of hydrogen and carbonmonoxide, known as syngas, and leaves a residue of amorphous elemental carbon called carbon black.
这一过程产生氢气和一氧化碳的混合物，也叫做合成气，剩余的是无定形的基本碳，也叫做炭黑。

The technique involves heating organic matter to produce a mixture of hydrogen and carbonmonoxide, called syngas.
