Application No. 09/138,217
THE CLAIMED SUBJECT MATTER
Claim 15 is directed to an apparatus and reads as follows:
15. An apparatus for carrying out an integrated process for the alkylation of organic
aromatic compounds, comprising:
(a) a distillation column reactor containing a bed of alkylation catalyst in the form of a
catalytic distillation structure and having an organic aromatic compound inlet above said bed of
alkylation catalyst and an olefin inlet below said bed of alkylation catalyst;
(b) a first overheads outlet connected to the top of said distillation column reactor to
remove unreacted organic compound and unreacted olefin;
(c) a first bottoms outlet connected to the bottom of said distillation column reactor to
remove alkylated product;
(d) a distillation column for separating mono substituted alkylated product from poly
substituted alkylated product having an alkylated product inlet in fluid communication with said
first bottoms outlet, a second overheads outlet to remove mono substituted alkylated product and
a second bottoms outlet to remove poly substituted alkylated product; and
(e) a transalkylator comprising:
(i) a vessel containing a plurality of transalkylation catalyst beds in series, the
effluent from each of said plurality of beds flowing to the next bed in series;
(ii) a plurality of poly substituted benzene inlets, one each of said poly substituted
benzene inlets being disposed upstream of each of said plurality of transalkylation
catalyst beds;
(iii) a head connecting each of said poly substituted inlets to said second bottoms
outlet;
(iv) valves in each of said plurality of poly substituted benzene inlets, said valves
being for directing poly substituted benzene to only so many of said plurality of
transalkylation beds as is required to obtain the optimum conversion of poly substituted
benzenes to mono substituted benzenes; and
