Title:
PROCESS FOR PRODUCTION OF ETHYLENE AND PROPYLENE
Document Type and Number:
WIPO Patent Application WO/2007/032448
Kind Code:
A1
Abstract:
The invention aims at providing a catalyst for the production of ethylene and propylene
from raw hydrocarbon by catalytic conversion which attains high yield and high
selectivity and is excellent in the resistances to deterioration by coking and
deterioration by regeneration. The invention relates to a process for the production
of ethylene and propylene which comprises bringing raw hydrocarbon containing
20% or more by mass of at least one olefin of 4 to 12 carbon atoms into contact with
a zeolite-containing molded catalyst satisfying the following requirements
(1) to (6) in a reactor to conduct catalytic conversion of the olefins: (1) the
zeolite is an intermediate-pore-diameter one having pore diameters of 5 to 6.5Å,
(2) the zeolite is substantially free from protons, (3) the zeolite contains
at least one metal selected from the group consisting of Group IB metals of the
periodic table, (4) the zeolite-containing molded catalyst is one made by using
silica as the binder, (5) the zeolite-containing molded catalyst has a crushing
strength of 2.5N/mm or above, and (6) the zeolite-containing molded catalyst
in H-form has a sodium content of 500ppm or below.
