Abstract

The present subject matter describes a gasification system (100) for gasifying a variety of feedstocks. A first stage gasifier (105) receives a feedstock either from a first group of feedstocks or a second group of feedstocks or both. The first stage gasifier decomposes the received feedstock to produce a first product. A second stage gasifier (115) is connected to the first stage gasifier (105) for receiving the first product. In addition, the second stage gasifier (115) receives a feedstock either from a third group of feedstocks or a fourth group of feedstocks or both. The second stage gasifier (115) gasifies the first product and the received feedstock to produce syngas.
