C3 Liquid-Phase Hydrogenation Catalyst
The C3 liquid-phase hydrogenation process is a crucial step in purifying propylene-rich streams derived from fluid catalytic cracking (FCC) units, steam crackers, propane dehydrogenation (PDH), or Methanol-To-Olefins (MTO) plants. This process aims to remove impurities such as methylacetylene (MA), propadiene (PD), and other reactive compounds, ensuring that the propylene meets polymergrade or chemical-grade specifications. The process selectively hydrogenates impurities (MA and PD) while preserving the maximum amount of propylene and minimizing the formation of green oil. For most of applications, the concentration of MAPD shall be reduced to less than 10 ppm.
Delion’s catalyst solution is designed to handle feedstocks with a wide range of impurity concentrations and selectively converts MAPD to propylene with approximately 80% selectivity. The C3 liquid-phase single-step hydrogenation process is a highly efficient and selective method for refining propylene streams, ensuring they meet stringent quality requirements for downstream applications.
