Alternate-fuel studies for diesel engines

This project includes studies of lignin and butanol for use as diesel fuels. An investigation of various mixtures containing lignin, diesel fuel, and various alcohols was made. Lignin, a wood derivative, would be an ideal substitute for diesel fuel. The lignin research included producing lignin/alcohol mixtures, investigating possible commercial sources of powdered lignin, investigating the solubility of lignin in diesel fuel and alcohols, and conducting engine tests using lignin mixture.
