Abstract
Official abstract text for this publication.
A system for preventing a catalyst from overheating is provided. The system includes: a first reactor filled with a catalyst at least in part and configured to receive reaction gas and produce product gas; and a second reactor configured to cool a catalyst discharged from the first reactor. The catalyst is circulated between the first reactor and the second reactor by injecting the catalyst cooled in the second reactor into the first rector.
First claim
Opening claim text (preview).
1 - 6 . (canceled) 7 . A method for preventing a catalyst from overheating, the method comprising: producing product gas by supplying reaction gas to a first reactor filled with a catalyst at least in part; and discharging some of the catalyst from the first reactor and supplying the catalyst to a second reactor; cooling the catalyst in the second reactor; and supplying the catalyst cooled in the second reactor to the first reactor. 8 . The method of claim 7 , wherein the producing the product gas comprises cooling the catalyst in the first reactor by allowing a first cooling fluid to pass through the first reactor. 9 . The system of claim 7 , wherein the catalyst is a catalyst of a particle shape having a diameter ranging from 1 to 9,000 micrometers, and wherein the producing the product gas further comprises injecting the reaction gas into the first reactor at a speed higher than a minimum fluidization velocity of the catalyst. 10 . The method of claim 7 , wherein the first reactor is a fluidized bed reactor and the product gas is produced in a state in which the catalyst in the first reactor is fluidized. 11 . The method of claim 7 , wherein the second reactor is filled with the catalyst discharged from the first reactor at least in part, and wherein the cooling the catalyst in the second reactor comprises cooling the catalyst in the second reactor by allowing a second cooling fluid to pass through the second reactor. 12 . The method of claim 7 , wherein the second reactor comprises a path to allow the reaction gas to pass through the second reactor, and wherein the reaction gas passing through the path of the reaction gas is pre-heated and supplied to the first reactor.
