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).
What is claimed is: 1. A system for preventing a catalyst from overheating, the system comprising: 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 at least partially filled with a catalyst discharged from the first reactor and configured to cool the catalyst discharged from the first reactor, wherein 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, wherein the second reactor comprises: a path of a cooling fluid passing through a catalyst bed in the second reactor; and a path to allow the reaction gas to pass through the catalyst bed in the second reactor, and wherein the reaction gas is pre-heated by heat exchange with the catalyst during passing through the path of the reaction gas and then supplied to the first reactor. 2. The system of claim 1 , wherein the catalyst is a catalyst of a particle shape having a diameter ranging from 1 to 9,000 micrometers. 3. The system of claim 1 , further comprising a path of another cooling fluid passing through the first reactor, and wherein the catalyst in the first reactor is cooled by the another cooling fluid. 4. The system of claim 1 , 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.
