Abstract: A novel portable fuel composition comprises 10 parts by weight of combustible polymer such as polypropylene, 20-35 parts by weight of organic solvent such as petroleum solvent and 3-9 parts by weight of coarse powder of fiber material such as sawdust, and optionally metal powder and dye. The composition is convenient for carrying and has a high degree of viscosity and calorific value. It can be utilized as a fuel for camping, for emergency, for preheating of a liquid fuel stove, for a simple portable cooking stove, or as a starter for igniting firewood.
