청구항

What is claimed is: 1. A gasification system comprising: a high temperature gasifier for operating at a first temperature; a low temperature gasifier for operating at a second temperature that is lower than the first temperature, the low temperature gasifier being located downstream from the high temperature gasifier; and a cyclone separator connected between an outlet of the high temperature gasifier and an inlet of the low temperature gasifier. 2. The gasification system of claim 1, wherein the first temperature of the high temperature gasifier inc...
