Claim 0:
1. A process for dehydrogenation of a hydrocarbon, the process comprising:
passing a sulfur containing feed stream comprising hydrocarbons to a dehydrogenation zone comprising at least one reactor receiving a dehydrogenation catalyst and being operated at dehydrogenation conditions to provide a product stream enriched in dehydrogenated hydrocarbons compared to the feed stream,
wherein the dehydrogenation conditions are based on a sulfur control index determined by one or more of: a pressure of the at least one reactor; a temperature associated with the at least one reactor; and a hydrogen to hydrocarbon ratio,
wherein a first dehydrogenation condition in the sulfur control index is selected and a second dehydrogenation condition is adjusted to a corresponding second dehydrogenation condition based on the sulfur control index and the selected, first dehydrogenation condition, and
wherein sulfur control index is determined using Equation 1, wherein Equation 1 comprises, INDEX
