What is Bio-oil?

Bio-oil is another option currently being researched to replace fossil fuels. A number of lignocellulosic biomass sources can be used for bio-oil production including purposely grown crops as well as agricultural residues.

Fast pyrolysis is currently the preferred option to produce Bio-oil, requiring high temperatures between 350 – 600˚C and short residence times of under 2 seconds. The process must also be performed in the absence of oxygen. The product from this process is comprised of mostly oil, around 70%, with the remainder being char and a number of gaseous products.

Bio-oil is a promising bio-fuel resembling light crude oil which will hopefully be one of the renewable fuel options that will replace and alleviate our reliance on fossil fuels.
