  • Process for producing propylene in the presence of a macroporous catalyst in the form of spherical beads
    Patent number: 7880048
    Abstract: A process for once-through conversion of a hydrocarbon feed comprising at least olefins containing 4 carbon atoms and at least olefins containing 5 carbon atoms is described for the production of propylene, said process comprising passing said feed into at least one reaction unit provided with at least one catalyst in the form of spherical beads with a diameter in the range 1 to 3 mm, each of said spherical beads comprising at least one zeolite and at least one alumina-based support and having a pore distribution such that the macroporous volume, measured by mercury porosimetry, is in the range 0.10 to 0.20 ml/g and the mesoporous volume, measured by mercury porosimetry, is in the range 0.25 to 0.35 ml/g.
