Abstract

In a previous work we examined co-pyrolysis behavior of the hydrothermally upgraded brown coal and waxes prepared from plastics. Char and gas yields increased for the pyrolysis conducted at either rapid or slow heating rate when compared with the yields calculated assuming independent pyrolysis of both the upgraded coal and wax, but no or small changes were found when using raw coal. These results indicated that extraction residue might be likely to show a significant synergetic effect in our co-pyrolysis method. In this work co-pyrolysis behavior of extraction residue obtained through high temperature solvent extraction and plastic wax was examined as one of the ways of utilizing the residues. A large synergetic effect was found in the co-pyrolysis using residual coals obtained from either a brown coal or a bituminous coal. It was also found that there was a threshold wax content over which a significant synergetic effect was found
