Abstract
The catalytic selective hydrogenation of multiunsaturated hydrocarbons, especially in pyrolysis products, to corresponding mono-olefins is a widely exploited way for the large-scale production of polymer-grade olefins as well as fuel upgrading. Thermodynamic and/or kinetic parameters could be effective for selective operation. The latter is primarily influenced by catalyst formulation, including promoters, support type, and metal dispersion and distribution. The solution to achieve an economically attractive commercial implementation lies in defining the optimal catalyst design and operating conditions. The theoretical and practical aspects of catalysis for the selective hydrogenation of acetylene to ethylene are reviewed and the potential new ways to improve catalyst formulation are examined.
