A pyrolytic reactor (10, 200, 300) for recovering carbon from certain plastics comprising: at least one reactor vessel (12), the at least one reactor vessel (12) having a first reaction chamber (34) and a second reaction chamber (42); a material delivery system (32) for delivering the certain plastics in particulate form to the first reaction chamber (34); a catalyst delivery system (46) for delivering a metal catalyst to the second reaction chamber (42); and a separator (20). The particulate plastic material is heated in the first reaction chamber (34) to a first temperature range so as to decompose into a collection of gases that are heated in the second reaction chamber (42) in conjunction with the metal catalyst to form a collection of post-reactor gases (comprised principally of hydrogen gas) having carbon coated catalytic material entrained therein, the separator (20) operable to separate at least some of the carbon coated catalytic material from the post-reactor gases.
A pyrolytic reactor for recovering carbon from certain plastics comprising:
A pyrolytic reactor according to any preceding claim, where the separator is a cyclonic separator.
A pyrolytic reactor according to any preceding claim where the metal catalyst is an iron-based catalyst.
A pyrolytic reactor according to any preceding claim, where each reaction chamber of the first reactor vessel is heated by an electric furnace.
A pyrolytic reactor according to any preceding claim, where the second reaction chamber is positioned above the first reaction chamber and a connecting chamber connects the first reaction chamber to the second reaction chamber.
A pyrolytic reactor according to any preceding claim, further including a perforated base plate located within the second reaction chamber, the perforations of the base plate being sized so as to allow gases to pass therethrough but prevent the metal catalyst from falling therethrough.
A pyrolytic reactor according to any preceding claim, further comprising a channel mixer, the channel mixer operable to deliver at least one of the following:
A pyrolytic reactor according to any preceding claim, where the material delivery system operates to unseal an opening in a sealed removable cartridge to allow the particulate plastic material contained therein to pass to a first feeder unit that delivers the particulate plastic material to the first reaction chamber.
A pyrolytic reactor according to any preceding claim, where the material delivery system has a feed rate of between 0.5 and 10 grams per minute.
A pyrolytic reactor according to claim any preceding claim, where the catalyst delivery system comprises a catalyst hopper that feeds the metal catalyst to a second feeder unit that delivers the metal catalyst to the second reaction chamber.
A pyrolytic reactor according to any preceding claim, where the catalyst delivery system has a feed rate of between 0.5 and 10 grams per minute.
A pyrolytic reactor according to any preceding claim, where the ratio of catalyst to particulate material is one of the following:
A pyrolytic reactor according to any preceding claim, where the post-reactor gases separated by the separator are oxidised in a combustion chamber.
A pyrolytic reactor according to any preceding claim, further including an energy recovery system to recover at least some of the chemical energy generated in the combustion chamber.
A method for recovering carbon from certain plastics, the method comprising the steps of:
