Document Type and Number:
Japanese Patent JPH07502286
Kind Code:
A
Abstract:
Apparatus and method for the pyrolysis of waste material which is not itself susceptible to heating by microwave radiation, which method comprises: (a) contacting the waste material, under an atmosphere wherein flame generation is substantially prevented, with a bed of pulverulent carbonaceous material which is susceptible to heating by microwave irradiation; and (b) heating the pulverulent material by means of microwave irradiation such that thermal energy is transferred from the pulverulent material to the waste material so as to cause substantial pyrolysis of the waste material, wherein the waste material is fed to an upper part of the bed of pulverulent material such that the waste material permitted to sink through the bed, and is pyrolysed within the bed. The apparatus comprises: (a) a container (9) which is inert to microwave radiation and capable of retaining the bed of pulverulent material; (b) a reaction chamber (8); (c) a conduit (19) for feeding the waste material to an upper part of the bed of pulverulent material; (d) a microwave generator (10); (e) air locks (12) and (18) for controlling the atmosphere in chamber (8) such that flame generation is prevented in chamber (8); and (f) outlet (20) for removal of gases, evolved on pyrolysis of the waste material, from chamber (8).
