“…For example, it was found by several authors, see ref. 6, that ethene hydrogenation cannot be fully prevented, even at very high ethyne partial pressures. This is in contrast with the classical view which predicts nearly 100% selectivity towards ethene in that case.…”

“…This is in contrast with the classical view which predicts nearly 100% selectivity towards ethene in that case. Therefore, it is now generally assumed, see for example, Men'shchikov et al [7], McGown et al [6]. Al-Ammar and Webb [S-IO] and refs.…”

“…It is known that acetylene hydrogenation produces ethylene, ethane, and C 4 1 oligomers, which are the precursors to ''green oil'' often found in industrial processes. 8,9 This ''green oil'' tends to adhere to the catalyst surface and leads to a gradual decline in the activity and selectivity of the hydrogenation process, which results in shortened catalyst lifetime and necessitates more frequent regeneration of the catalyst, thereby leading to increased operating costs. In addition, mass and heat transfer property was the major factor that affects the selectivity for acetylene hydrogenation to a significant extent.…”

“…Selective catalytic hydrogenation of acetylene impurity (∼0.3–3 vol %) has been the target of ethylene polymerization processes. It is known that acetylene hydrogenation produces ethylene, ethane, and C 4 + oligomers, which are the precursors to “green oil” often found in industrial processes 8, 9. This “green oil” tends to adhere to the catalyst surface and leads to a gradual decline in the activity and selectivity of the hydrogenation process, which results in shortened catalyst lifetime and necessitates more frequent regeneration of the catalyst, thereby leading to increased operating costs.…”
