The lest results have shown that I he highest recovery of coal is 99% and deash efficiency is 20% using neutral oil of liquified fuel and waste cooking oil as agglomeration oil.
In this paper technological process of catalytic cracking and catalytic reforming and post-processing of waste fat and oil are discussed to prepare the qualified liquid fuel oil.
To make rational use of industrial waste materials and reduce pollution, and to supply the substitute fuel for oil fired furnace, the writers have developed a new type liquid fuel Still Residue.
