SYSTEMS AND DEVICES FOR FUEL CONVERSION

摘要

A chemical looping system may include a first reactor and a second reactor, the second reactor connected to the first reactor by a first connection and a second connection. The first connection may be disposed downstream of the first reactor and upstream of the second reactor and the second connection may be disposed downstream of the second reactor and upstream of the first reactor, thereby defining a loop in which solid particles may circulate. The first reactor may be a co-current moving bed reactor. The second reactor may be a fluidized bed reactor. The first connection may include a non-mechanical zone seal and a solids circulation device. The second connection may include a gas-solids separation device, a solids storage vessel, and a non-mechanical zone seal.
