Appeal 2007-2549
Application 10/163,206
[4] Preferred alkylate products are C5+ alkylates with a minimum, e.g.,
less than 30 wt. %, of C9+ alkylates, having a RON of 90 or higher
(Specification 15:8-12 and 24-26).
[5] "RON is a measure of the anti-knock rating of gasoline and/or
gasoline constituents. The higher the RON, the more favourable the
anti-knock rating of the gasoline will be." [Specification 15:20-21.]
[6] The solid acid alkylation catalyst comprises a hydrogenating metal
component and a solid acid component (Specification 13:10-11).
[7] Suitable hydrogenating metals include Group VIII transition metals,
e.g., platinum and/or palladium (Specification 13:13-16).
[8] Suitable solid acid components include zeolites (Specification at
13:22 to 14:3)
[9] Generally, the mild regeneration step is carried out at a temperature of
233 to 523 K (i.e., -40 to 249°C) and a pressure of 1 to 100 bar
(Specification 9:25-26).
[10] According to the specification, "catalyst is regenerated by being
contacted with hydrogen in the presence of formed alkylate"
(Specification 10:23-24).
[11] Typically, "the hydrogen will be dissolved in the alkylate-containing
mixture, i.e., the alkylate-containing product stream (embodiment 1)
or the mixture containing the formed alkylate which is still present
after cycling the reactor(s) from the alkylation mode to the
regeneration mode (embodiment 2)" (Specification 10:24-27).
[12] Further according to the specification,
Optionally, the reactors may be flushed with a
hydrocarbon-containing stream, e.g., an alkylatable
compound-containing stream or an alkylate-
