POLYMER BONDED REFRACTORY EXTRUDATE |
摘要 |
A shaped refractory unit such as a high temperature hydrocarbon steam reforming catalyst support is made by extruding a composition comprising refractory oxidix material and hydrophilic polymers of two types differing in their tendency to shear-thinnings, then calcining the extrudate. Use of such polymers makes it possible to extrude clay-free compositions and thus to produce silica-free shaped units. |
