摘要

This study demonstrates the potential for using pyrolysis products of oil-containing waste, including oil sludges, in the synthesis of porous ceramics. The high carbon content in oil sludge pyrolysis products determines their suitability for use as a burnout additive with the potential to partially replace the green body in the production of aluminosilicate ceramics. The presence of both naturally occurring and industrial metal oxides in the pyrolysis products contributes to a reduction in firing temperature from 1150°C to 1080°C, compared with clay-based ceramics without additives. It is recommended that the pyrolysis products of oil-containing waste be introduced into the raw material composition in amounts of up to 20 wt.%.
