Preparation of solid biofuel derived from palm kernel shell waste via pyrilysis and hydrogenation process

The need for energy is always expanding along with industrialization and population increase, and the availability of energy supplies cannot keep up with the mounting consumption. In 2000, one estimate predicted that about 20 million metric tons of CO2 will be released into the atmosphere yearly. Wh...
