Abstract
The present disclosure relates to a device that includes a filter element and a catalyst, where the filter element is configured to remove particulate from a stream that includes at least one of a gas and/or a vapor to form a filtered stream of the gas and/or the vapor, the catalyst is configured to receive the filtered stream and react a compound in the filtered stream to form an upgraded stream of the gas and/or the vapor, further including an upgraded compound, and both the filter element and the catalyst are configured to be substantially stable at temperatures up to about 500° C.
Claims11
A device for upgrading a pyrolysis vapor, the device comprising:
- a filter element;
- and
- a catalyst, wherein:
- the filter element removes particulate from a stream comprising the pyrolysis vapor to form a filtered stream of the pyrolysis vapor,
- the catalyst receives the filtered stream,
- the catalyst comprises a heteropolyacid,
- the catalyst reacts with a compound in the filtered stream to form an upgraded stream of the pyrolysis vapor, further comprising an upgraded compound, and
- both the filter element and the catalyst are substantially stable at temperatures up to about 500° C.
A system for upgrading a pyrolysis vapor, the system comprising:
- a catalytic hot-gas filter (CHGF) configured to receive an inlet stream comprising at a pyrolysis vapor, wherein:
- the CHGF comprises a filter element and a catalyst,
- the filter element is configured to remove particulate from the inlet stream comprising a pyrolysis vapor to form a filtered stream of the pyrolysis vapor,
- the catalyst comprises a heteropolyacid,
- the catalyst is configured to receive the filtered stream and react a compound in the filtered stream to form an upgraded stream of the pyrolysis vapor, further comprising an upgraded compound, and
- both the filter element and the catalyst are configured to be substantially stable at temperatures up to about 500° C.
