Refractory CO/sub 2/ acceptor gasifier lining reviewed
Laboratory examination of several of the refractory materials used in lining this gasifier led to the conclusion that the use of 50 percent silica-alumina castable material in hydrogasification environments results in reasonably good material life and performance. The beneficial effects of increased compressive strength and erosion resistance by steam leaching of the refractories, in conjunction with the interaction of alkali from the lignite and lime from the acceptor, far outweigh any observed degradation, at least at this stage of the liner's service life. Whether further reaction would occur with continued exposure and whether further reaction would enhance performance or cause deterioration cannot be determined.
