Abstract
A catalytic reactor apparatus is disclosed for continuous conversion of plastic wastes into liquid fuels by dispersing a cracking catalyst in molten plastics and cracking plastic macromolecules into smaller hydrocarbons within boiling point range of gasoline and diesel fuel at temperatures significantly lower than thermal pyrolysis and thermal cracking. The catalyst/plastic mixing and heat transfer from the reactor wall to the reaction zone are enhanced using non-Newtonian stirrer. A catalytic membrane filter is used to keep the catalyst fines and unconverted plastic particulates inside the reactor while letting the desirable hydrocarbon vapor be withdrawn out of the reactor.
