  • Patent number: 5096462
    Abstract: A novel ignition promoter; a process for preparing the ignition promoter which comprises removing cellulose from biomass, such as wood, bagasse, corncobs, straw, hay, or newspaper, and thereafter nitrating the remainder after treatment with an oxirane; and a fuel suitable for use in an internal combustion engine, such as a Diesel engine, containing an alcohol, such as methanol or ethanol, and said ignition promoter. Cellulose can be removed from the biomass by treating it with an aqueous nitric acid solution. The material remaining after cellulose removal can be nitrated using an aqueous solution of nitric acid. Nitration is carried out by reacting the material after cellulose removal with an oxirane, such as ethylene oxide, and thereafter nitrating the resulting product using aqueous nitric acid in combination with a dehydrating agent, such as sulfuric acid.
