摘要：Described herein are systems and methods for reducing cumulative depositionand unwanted secondary thermal reactions in pyrolysis and other thermal conversion

processes. In an embodiment, a system comprises a device, referred to as a reamer, forremoving product deposits between thermal conversion and condensation operations ofa pyrolysis process. The reamer may comprise, but is not limited to, a mechanicalreciprocating rod or ram, a mechanical auger, a drill bit, a high-temperature wiper, brush,or punch to remove deposits and prevent secondary reactions. Alternatively or inaddition, the reamer may use a high-velocity curtain or jet (i.e., a hydraulic or pneumaticstream) of vapor, product gas, recycle gas, other gas jet or non-condensing liquid toremove deposits. Preferably, the reamer removes deposits during the pyrolysis processallowing for continuous operation of the pyrolysis process.
