The objective of this project is to conduct experiments to obtain data for the design of a single-stage, fluidized-bed, peat gasifier using steam and oxygen. The economics of converting peat to synthesis gas and to SNG by a single-stage fluidized-bed gasifier will also be evaluated. The equipment used in this project is the same as that used previously, with some modifications, to investigate the gasification characteristics of chars from Minnesota, North Carolina, and Maine peats. Some preliminary observations can be made concerning the results obtained to date. Increasing the oxygen-to-carbon feed rate increases the carbon gasified. For feed peat containing a relatively high moisture content (greater than about 20 wt %), increasing the gasification temperature from about 1620/sup 0/ to 1725/sup 0/F does not significantly increase the carbon gasified. For peat with a low moisture content (less than about 10 wt %), however, increasing the gasification temperature does increase the amount of carbon gasified.
