Abstract
A process is presented for controlling the output of monoalkylated benzenes. The alkylbenzenes are linear alkylbenzenes and the process controls the 2-phenyl content of the product stream. The control of the process to generate a linear alkylbenzene with a 2-phenyl content within a desired range by recycling a portion of the effluent from the alkylation reactor to the inlet of the reactor.
Claims6
A process for controlling the 2-phenyl content in the benzene alkylation process, comprising:
- passing a benzene stream to an alkylation reactor;
- passing a linear olefin to the alkylation reactor;
- reacting the linear olefin with the benzene over a catalyst to produce an effluent stream comprising benzene and alkylbenzene;
- measuring the 2-phenyl content of the alkylbenzene in the effluent stream;
- passing a portion of the effluent stream to the alkylation reactor to increase the benzene to olefin ratio of the feed;
- and
- controlling the benzene to olefin ratio in the feed through control of the portion of the second stream to the reactor in response to the 2-phenyl content, wherein the desired 2-phenyl content is between preset limits.
