Automated catalyst regeneration in a reactor
This patent describes an apparatus for the automatic regeneration of catalyst used in a process for obtaining ethylene in an exit stream of a reactor from acetylene in a feed stream of the reactor. The reactor has regeneration means for regenerating the catalyst and comprises: first sensor means including a chromatograph operatively connected to the feed stream for sensing a concentration of acetylene and hydrogen in the feed stream; second sensing means including a chromatograph operatively connected to the exit stream for sensing a concentration of acetylene in the exit stream; a control system connected to the first and second sensor means and to the regeneration means of the reactor for calculating a value for selectivity of the catalyst and an auxiliary reactor containing catalyst for the process connected to the exit stream and the feed stream.
