Abstract

The system for processing waste includes both a fixed bed reactor and a fluidized bed reactor. The fixed bed reactor receives a first waste material and produces a first set of reaction products. The fluidized bed reactor is adapted for receiving a second waste material and producing a second set of reaction products. The first and second sets of reaction products may be selectively and adjustably mixed to produce a mixed set of reaction products. At least one cyclone separator receives the reaction products and separates and collects solids (waxes) from the product stream. At least one condenser receives the product stream and removes a condensable liquids from the product stream. The condensable liquids are collected, and a gas-liquid separator removes any remaining liquid from the gas stream. The remaining gas is then output as gaseous product.

Dependent claims

A system for processing waste, comprising:

a fixed bed reactor adapted for receiving a first waste material and producing a first set of reaction products;
a fluidized bed reactor adapted for receiving a second waste material and producing a second set of reaction products;
at least one external source of reaction gas selectively in fluid communication with at least one of the fixed bed reactor and the fluidized bed reactor to selectively facilitate a reaction in the corresponding reactor;
a conduit system connected to the fixed bed reactor, the fluidized bed reactor, and the at least one external source of reaction gas, the conduit system including a plurality of valves to selectively permit separate or simultaneous operation of the fixed bed reactor and the fluidized bed reactor and to selectively mix the first and second sets of reaction products to produce a mixed set of reaction products;
at least one cyclone separator and an attached solids collection vessel for selectively receiving the first set of reaction products, the second set of reaction products, and the mixed set of reaction products and separating and collecting solids therefrom to produce a mixed set of fluids;
at least one condenser and an attached liquids collection vessel for receiving the mixed set of fluids and producing a liquid stream and a gas stream, the liquid from the liquid stream being collected in the liquids collection vessel;
and
a gas-liquid separator and an attached gas collection vessel for removing remaining liquid from the gas stream, gas from the gas stream being collected in the gas collection vessel.
