Reaction device for producing hydrocarbons from synthesis gas

摘要

Disclosed is a reaction device for producing hydrocarbons from synthesis gas, in which hydrocarbons, olefins, oxygenates, etc., are produced over a Fischer-Tropsch catalyst by using synthesis gas, so that the catalyst particles can easily be from a slurry which is discharged to the outside. That is, the present invention provides a reaction device for producing hydrocarbons from synthesis gas, in which an internal filter system for separating particles enlarged due to agglomeration phenomenon of a catalyst is installed inside the reactor, and a separating device is separately disposed outside, such that it is possible to recirculate only particles having a size appropriate for performing F-T synthesis in the slurry phase, and additionally, it is possible to effectively discharge and process a catalyst aggregated due to a combination of fine catalyst particles, the catalyst chipped off during the operation, etc., liquid hydrocarbon, resulting water, etc., in the slurry phase reactor.

主权项

1. A reaction device for producing hydrocarbons from synthesis gas which includes a reactor (R) for reacting synthesis gas over a Fischer-Tropsch catalyst and a synthesis gas distributor (D) installed inside the reactor (R) to distribute synthesis gas, the reaction device comprising:
an internal filter (F0) installed inside the reactor (R); a lower separating device (F1) connected with a lower outlet (B) formed at a bottom of the reactor (R) to filter or separate a slurry including a catalyst lump; an upper separating device (F2) connected with an upper outlet (A) formed at a predetermined position at an upper side of the reactor (R) to filter or separate a slurry mixed with a fine catalyst; a gas discharge means configured to discharge non-reacted gas generated inside the reactor (R); a recirculation discharge means configured to recirculate or discharge the catalyst filtered in the upper and lower separating devices (F2 and F1); and a slurry discharge path (Ex) formed between the internal filter (F0) and an inner wall of the reactor (R).
