Apparatus for processing materials in supercritical fluids

摘要

An improved apparatus comprises a high strength enclosure; a capsule disposed inside the high strength enclosure, wherein the capsule is configured to contain one or more materials in an environment having a supercritical fluid; a heating device disposed between the high strength enclosure and the capsule, wherein the heating device is configured to transfer heat into the environment within the capsule, such that the environment becomes heated and self-pressurized from the heat, wherein the high strength enclosure is configured to surround and bear against the capsule to counterbalance internal pressures within the capsule; and thermal insulation disposed between the high strength enclosure and the heating device, wherein the thermal insulation is configured to retain heat within the capsule and to reduce heat transfer into the high strength enclosure.
