OleMax® 250

SELECTIVE ACETYLENE HYDROGENATION CATALYSTS FOR ETHYLENE PLANTS WITH "FRONT-END" CONFIGURATIONS 

OleMax® 250 series catalysts are designed for selective hydrogenation of acetylene, methyl acetylene, propadiene and butadiene to produce ethylene in front-end plant configurations. The catalysts of this series offer optimal selectivity, long cycle life, and high operational stability while minimizing acetylene slip.

The promoted-palladium catalysts have been in commercial operation for decades at numerous world-scale ethylene production facilities. We offer a choice of catalysts in a variety of shapes and sizes to suit different plant and process requirements.

Benefits

  • Excellent overall operability
  • High activity, minimized risk of off-specification production
  • High selectivity, maximized production profits
  • Wide operating temperature window
  • High tolerance to CO swings, minimized risk of a thermal runaway
  • Long-term stability, increased cycle lengths

OleMax® 260

ULTRA-SELECTIVE ACETYLENE HYDROGENATION CATALYST FOR ETHYLENE PRODUCTION IN "FRONT-END" PROCESS CONFIGURATIONS

OleMax® 260 is a new generation selective acetylene hydrogenation catalyst designed for ethylene production using front-end process configurations. While OleMax series catalysts have been proven in commercial operation for decades, the new catalyst offers ultra-high selectivity for acetylene hydrogenation yet virtually no reactivity with ethylene. This maximizes product yields while minimizing energy and raw material consumption.

Moreover, the promoted-palladium catalyst all but eliminates the risk of runaways by pushing runaway temperature far beyond standard operating temperature. The exceptional selectivity and consequent stability of OleMax® 260 ensures reliable, on-specification performance over an unprecedentedly wide operating range, even at the extremely low CO levels typical of new cracking furnace technologies.

Benefits

  • Exceptionally wide operating window even at challenging very low CO levels (<100 ppm)
  • Ultra-high stability against thermal runaway reactions due to rapid CO concentration changes
  • Near perfect selectivity to polymer-grade ethylene, essentially independent of CO level
  • Optimized activity to work in all de-ethanizer plants as a drop-in replacement
  • Simplified and substantially accelerated start-up procedures, greatly reducing time to reach full-rate, on-specification production
  • Global Engineering Service to support customers
