Flash hydropyrolysis of coal. Quarterly report No. 1, January 1--March 31, 1977
The 1 lb/hr Flash Hydropyrolysis experimental equipment has been completed and is in operation. The unit was originally designed for the maximum operating conditions of 4000 psi and 800/sup 0/C. To date it has been successfully operated at up to 3000 psi and 815/sup 0/C with coal feed rates in excess of 2 lbs/hr. Product analysis is accomplished with the use of an on-line process gas chromatograph designed to measure CO, CO/sub 2/, H/sub 2/O, CH/sub 4/, C/sub 2/H/sub 4/, C/sub 2/H/sub 6/, C/sub 6/H/sub 6/, C/sub 7/H/sub 8/, C/sub 8/H/sub 10/ and all hydrocarbons greater than or equal to C/sub 9/, every 6 minutes. Samples of the chromatograph can be taken from any of 6 sample taps including three located at 2 foot intervals along the 8 foot reactor. Carbon conversions in excess of 40 percent to gaseous products and 20 percent to liquid products have been observed. Preliminary process design and economic evaluations show the process to be both technically and economically feasible for commercial application.
