Abstract

A reactive process for converting composite plastic waste into hydrogen gas and a reactor system for effecting such process.

Claims (20)

1 . A reactor system for converting composite waste into hydrogen gas, comprising:

a first reactor containing reactants composite waste and nitrogen or other non-oxydizing gas, wherein the composite waste is heated to emit hydrocarbon gas;

a second reactor containing sulfur, wherein the hydrocarbon gas from the first reactor is reacted with sulfur to produce hydrogen sulfide;

a first buffering tank in which the hydrogen sulfide from the second reactor is pressurized and stored to produce a consistent pressure flowing feed to a third reactor;

the third reactor wherein the hydrogen and sulfur of the hydrogen sulfide from the first buffering tank are disassociated into liquid sulfur and hydrogen gas products with a heating element and then separated with a membrane, allowing the liquid sulfur product to drain into a collection tank; and

a second buffering tank in which the hydrogen gas from the third reactor is stored and buffered or normalized for commercial use.

2 . The reactor system of claim 1 , wherein each reactor and tank is connected in sequence by a three-way valve connecting to an atmospheric flare and a pump, wherein the pump forwards the product of the preceding reactor or tank to the next reactor or tank.

3 . The reactor system of claim 1 , wherein the first reactor is initially purged of air with a vacuum and nitrogen or other non-oxydizing gas is pumped into the first reactor from an inlet in place of the purged air.

4 . The reactor system of claim 1 , wherein the liquid sulfur produced by the third reactor is recycled for use in the second reactor.

5 . The reactor system of claim 2 , wherein one or more of the three-way valves are automatically shifted to atmospheric flare whenever all or part of the system is overpressurized.

6 . The reactor system of claim 1 , wherein the first reactor chamber is operated at a pressure of approximately 20% of ambient atmospheric pressure and a temperature range of 150 C to 300 C.

7 . The reactor system of claim 1 , wherein the first reactor is cylindrical, comprises a motor and an axis, wherein the first reactor spins on the axis.

8 . The reactor system of claim 7 , wherein the spin rate is appropriate for efficient heat transfer and the controlled decomposition of composite hydrocarbon waste within the reactor.

9 . A process of converting composite waste into hydrogen gas using the reactor system of claim 1 , comprising the steps of:

feeding composite waste into the first reactor;

partially filling the second reactor with sulfur;

purging the air from the first reactor and replacing the air with nitrogen or other non-oxydizing gas;

initiating the heating of the first reactor;

periodically removing the unreacted residue of the composite waste from the first reactor and the liquid sulfur from the second reactor when each is spent; and

replacing composite waste and sulfur as needed.
