Definitions
- disproportionation is used herein to mean the conversion of hydrocarbons to new hydrocarbons of both higher and lower molecular weight.
- pentane may be disproportionated according to the reaction:
- the relatively high olefin concentration in the product from the reaction zone when operated at 875 F. versus the relatively low olefin concentration when operating at the lower temperatures illustrates the advantage of operating the saturated hydrocarbon disproportionation zone in the presence of no more than about 5 weight percent olefins and preferably substantially less olefins, as, for example, less than 1 weight percent olefins.
