Pyrolysis of rice husk and sawdust for liquid fuel

The paper is focused on studying how to convert rice husk and sawdust into liquid fuel. Rice husk, sawdust and their mixture were pyrolyzed at the tem perature between 420℃ and 540℃, and the main product of liquid fuel was obtain ed. The experimental result showed that the yield of liquid fuel heavily depende d on the kind of feedstock and pyrolysis temperature. In the experiments, the ma ximum liquid yields for rice husk, sawdust and their mixture were 56% at 465℃, 61% at 490℃ and 60% at 475℃ respectively. Analysis with GC-MS and other appara tus indicated that the liquid fuel is a complicated organic compound with low ca loric value and can be directly used as fuel oil without any up-grading. As a cr ude oil, the liquid fuel can be refined to be vehicle oil.
