<p>Disclosed is a solid fuel which contains, on air dried basis, 20-60% by mass of fixed carbon, 30-66% by mass of volatile content and 3-6% by mass of ash content, while containing 6% by mass or less of moisture content. The solid fuel has a higher calorific value of 20-30 MJ/kg on air dried basis. This solid fuel can be produced by a method for producing a solid fuel, said method comprising a supply step wherein shells left after obtaining kernel oil by oil-pressing palm fruit seeds are supplied to a heating means and a heating step wherein the shells are heated at a temperature of 240-350°C by the heating means, thereby obtaining a heat-treated solid of the shells.</p> |
