Acetylene in ethylene cracker product interferes in downstream polymerization processes.
Rezel-ROC, a palladium on alumina catalyst for the selective hydrogenation of acetylene to primary C2-C4 olefins, maximizes the production of light olefins for downstream polymerization processes with conversion rates exceeding 99%.
In addition to ethylene cracker applications, C4s and C5s from MTO processes are selectively hydrogenated to convert acetylenes and dienes to primary olefins.
Rezel-ROC is also useful in the conversion of 1,3 butadienes to primary butenes prior to the alkylation process, where butadienes in alkylation feed increase the consumption of sulfuric acid, leading to the generation of high molecular weight, low octane gasoline.
