More Information
Summary:A system for pyrolyzing coal comprising: at least one reaction chamber capable of pyrolyzing a combination of coal in a supercritical carbon dioxide (C0 2) atmosphere; and a recuperating and condensing circuit that removes at least some dissolved pyrolysis products from the supercritical C02 atmosphere and then recovers C02 for reuse in the reaction chamber; wherein the recuperating and condensing circuit includes one or more recuperator/collector stages, each recuperator/collector stage having a heat exchanger and condensate collector connected to receive C02 atmosphere from the reaction chamber as a C02 process stream, transfer heat from the C02 process stream to a C02 return stream to obtain a cooled C02 process stream, and condense and collect pyrolysis products from the cooled C02 process stream.
