Abstract
A start-up method for contacting a feed stream with fluidized catalyst is disclosed. The start-up method comprises reacting a feed stream over a catalyst to produce a gas stream and spent catalyst. The gas stream is separated from the spent catalyst. The separated gas stream is passed to a compressor. The operating condition associated with the compressor is measured. Based on the measured operating condition associated with the compressor, one or both of a supplemental hydrocarbon stream and a supplemental hydrogen gas stream is provided to the compressor to meet a predetermined operating condition associated with the compressor.
