Process and apparatus for production and filtration of aminoalcohols using a continuous stirred tank slurry reactor

摘要

Disclosed are processes and apparatuses for producing a reaction product and enabling the reaction product to be removed from a reactor operating at an elevated pressure, while simultaneously maintaining the gas pressure and retaining the catalyst inside the apparatus.

主权项

1. An apparatus comprising:
a reactor adapted to react a nitroalcohol with hydrogen over a catalyst at a reaction pressure between about 2×106 Pa and about 7×106 Pa to produce a reaction product, wherein the reaction product is an aminoalcohol; a filtration apparatus for filtering the catalyst from the reaction product, such that the catalyst accumulates in the filtration apparatus, wherein the filtration apparatus is located outside of the reactor; and a backpulse system for returning accumulated catalyst from the filtration apparatus to the reactor, wherein the backpulse system is provided by a hydraulic piston or a pump and is configured to push a liquid through the filtration apparatus to return the catalyst accumulated in the filtration apparatus to the reactor.
