Once you know what biomass is chemically composed of you can see clear differences with oil. Its is also important that you know that the O’s stand for oxygen and the C’s stand for carbon. 

The biggest difference between them is that oil chemicals are large straight lines while the biomass chemicals are small, circular and full of O’s. They look very different and this means that to turn one into the other we have to do a lot of work and spend a lot of money. We have actually been turning oil chemicals into biomass chemicals for a very long time at considerable cost, so it is ironic that we are now trying to turn biomass chemicals into oil chemicals at considerable cost.
