Investigation of carbon monoxide disintegration of refractories in coal gasifiers. Annual progress report, June 1, 1978-May 30, 1979

TLDR: In this paper, three refractory compositions were examined: 90+ wt % Al/sub 2/O/sub 3/ and 50 + wt% Al/ sub 2.5 % O/sub 1.5% Fe and Fe 2.0% Fe 3.

Abstract: Three refractory compositions were examined: 90+ wt % Al/sub 2/O/sub 3/ and 50+ wt % Al/sub 2/O/sub 3/ calcium aluminate bonded castables and 90+ wt % Al/sub 2/O/sub 3/ phosphate bonded ramming mix. Each composition was doped with from 0 to 2.0 wt % (iron equivalent) Fe and Fe/sub 2/O/sub 3/. Test samples were prepared according to conventional procedures and at least 4 samples of each composition were exposed for 100 h at 500/sup 0/C to the various gases. Atmospheric pressure tests used a flow rate of 5 l/h and the high pressure experiments used a comparable amount of gas but not a continuous flow-through procedure.
