Abstract
Official abstract text for this publication.
A solids circulation system receives a gas stream containing char or other reacting solids from a first reactor. The solids circulation system includes a cyclone configured to receive the gas stream from the first reactor, a dipleg from the cyclone to a second reactor, and a riser from the second reactor which merges with the gas stream received by the cyclone. The second reactor has a dense fluid bed and converts the received materials to gaseous products. A conveying fluid transports a portion of the bed media from the second reactor through the riser to mix with the gas stream prior to cyclone entry. The bed media helps manipulate the solids that is received by the cyclone to facilitate flow of solids down the dipleg into the second reactor. The second reactor provides additional residence time, mixing and gas-solid contact for efficient conversion of char or reacting solids.
First claim
Opening claim text (preview).
What is claimed is: 1. A feedstock processing system having a solids circulation system configured to capture and convert reactive solids, comprising: a first reactor configured to receive a feedstock and, in response to said feedstock, output a first stream via a first conduit, the first stream comprising gas and particulate matter; a second reactor having a dense fluid bed and configured to receive reactive solids comprising a first portion of said particulate matter and also…
