Abstract
A reactor for hydrocarbon production that separates wax reaction products from lightweight gaseous reaction products. The reactor has a housing, a catalyst bed, a product recovery zone, and a stripping zone. The catalyst bed can be provided in multi-tubular and other fixed bed configurations. The stripping zone receives light-weight gas reaction products from the product recovery zone, while a gas outlet of the housing receives non-lightweight gaseous hydrocarbon reaction products from the product recovery zone. A wax outlet of the housing receives wax products from the product recovery zone.
Claims41
A reactor for producing a desired product, comprising:
- a housing having an outer portion, a central portion, and a longitudinal axis passing through the central portion, the outer portion being radially spaced from the central portion, the housing defining a circumferential coolant inlet channel within the outer portion of the housing;
- and a circumferential coolant outlet channel within the central portion of the housing, the coolant inlet channel being configured to receive at least one coolant material;
- and
- a plurality of coolant plates circumferentially spaced within the housing, wherein each coolant plate of the plurality of coolant plates extends radially between the coolant inlet channel and the coolant outlet channel, wherein each coolant plate defines a plurality of radial coolant channels that extend radially between, and in fluid communication with, the coolant inlet channel and the coolant outlet channel, and wherein the plurality of radial coolant channels are spaced apart relative to the longitudinal axis of the housing.

A reactor for producing a desired product, comprising:
- a housing having an outer wall, a first circumferential inner wall, a second circumferential inner wall, a perforated circumferential wall, and a longitudinal axis, the first circumferential inner wall being spaced radially outwardly from the second circumferential inner wall, the perforated circumferential wall being positioned radially between the first circumferential inner wall and the second circumferential inner wall, the outer wall and the first circumferential inner wall cooperating to define a coolant inlet channel, the coolant inlet channel being configured to receive at least one coolant material, the second circumferential inner wall defining a coolant outlet channel;
- a catalyst bed extending circumferentially within the housing and defined between the first circumferential inner wall and the perforated circumferential wall, the catalyst bed being configured to receive at least one catalyst;
- and
- a plurality of coolant plates, each coolant plate of the plurality of coolant plates spanning radially across the catalyst bed between the coolant inlet channel and the coolant outlet channel, each coolant plate defining at least one radial coolant channel positioned in fluid communication with the coolant inlet channel and the coolant outlet channel,
- wherein the perforated circumferential wall of the housing is configured to permit radial passage of the desired product, and wherein the perforated circumferential wall cooperates with the second circumferential inner wall to define a product collection area.
