In this program, hydrogasification tests are being conducted in two separate tasks. The objective of Task 1 is to study the gasification characteristics of peats from Florida and Alaska. The objective of Task 2 is to determine the effects of dewatering methodologies on the gasification characteristics of peat. Peats dewatered by three methods have been selected for testing in this task. These are: North Carolina peat harvested by the sod peat method, Minnesota peat dewatered in a sulzer belt press and thermally dried at approx. 300/sup 0/F in a Sulzer fluidized-bed dryer, and Minnesota peat dewatered in a Sulzer belt press and thermally dried in a tray dryer at 250/sup 0/F. To date a total of four hydrogasification tests have been conducted with a reed sedge peat from Florida (Seffner, Florida) completing the planned tests. The tests were conducted with hydrogen, steam and hydrogen, and hydrogen and nitrogen mixtures, at a pressure of 250 psia, and at maximum coil temperatures ranging from 1080/sup 0/ to 1510/sup 0/F. The operating conditions and results of these tests are summarized in Table 1. A typical chemical analysis of the Florida peat is compared with that of a Minnesota, North Carolina, and a Maine peat in Table 2. The Florida peat had a calorific value similar to that of the Minnesota peat. Its ash content was higher than that of the others, but its oxygen content was lower.
