CATALYSTS FOR SELECTIVE HYDROGENATION OF DIOLEFINS (E.G. BUTADIENE) IN C4/C5 LIQUID FEEDS
OleMax® 450 series catalysts are designed for selective hydrogenation of diolefins (dienes), such as butadiene or vinylacetylene (VAC), in C4 and C5 liquid feeds. Butadiene is found in small quantities in fluid catalytic cracking (FCC) butane-butene streams, where it can cause high acid consumption and sludge in alkylation units. Thanks to their high selectivity and performance, OleMax 450 series catalysts effectively hydrogenate diolefins, thereby minimizing these operational problems. The palladium-based catalysts are available in a variety of shapes and sizes to suit different plant designs and requirements.
Benefits
- Enables total saturation of C4 and/or C5 streams
- Effectively reduces acid consumption and sludge in alkylation units
- Enhanced promoter significantly improves diolefins loss and operating time
