You can try to dissolve lignin with ethanol and make a perfect heavy fuel oil for diesel engines. For further details you can write to me on [email protected]
I agree with Dr. Cordner, Lignin is a very versatile component of nature. when separated from Biomass, it can be spray dried to get powde and used as binder in Road construction, pharma etc. Also it can be used as fuel in the incinerator boilers. In advanced Biofuels research, Lignin Ethanol Oil is been explored as a sulphur -less Sustainable Marine Fuel pitted against the Heavy Fuel Oil (Bunker Fuel).
