MONOMERIZATION OF DICYCLOPENTADIENE AND HYDROGENATION OF CYCLOPENTADIENE IN A STREAM OF METHANE OVER PALLADIUM-RUTHENIUM ALLOY

1. Methane can be used as a heat-transfer agent for the monomerization of dicyclopentadiene and as carrier gas for the hydrogenation of cyclopentadiene (CPD) to cyclopentene at membrane catalysts consisting of a palladium alloy with 9.8% of ruthenium. 2. Increases in the selectivity and in the yield of cyclopentene were found during hydrogenation of CPD with hydrogen passing through the membrane catalyst compared with the delivery of a mixture of CPD vapor and hydrogen at the same catalyst. © 1980 Plenum Publishing Corporation.
