Process for enhancing catalytic response of asphalt oxidation catalyst.

摘要

Sodium carbonate, sodium sesquicarbonate and other carbonate catalysts ground to fine particle sizes (95% plus passing through a 200 mesh sieve (75µm) are more active than commercially available grades of such catalysts when oxidizing asphalt fluxes, permitting reduction in oxidation time, reduction in required catalyst quantities and improvement in product quality.
