Abstract
Normal paraffinic hydrocarbons, having from three to about twenty carbon atoms per molecule, are dehydrogenated to produce corresponding linear mono-olefins.These are separated from unreacted paraffins, preferably via an adsorption-separation technique. Raffinate, containing the unreacted normal paraffins, is subjected to mild hydrotreating, as is the hydrogen-rich vaporous phase recovered from the dehydrogenation zone product effluent,to saturate the olefins therein. Hydrotreated effluent is introduced, generally in admixture with fresh feed paraffins, into the dehydrogenation reaction zone.This technique avoids by-product dehydrogenation reactions otherwise resulting in non-linear mono-olefins, di-olefinic hydrocarbons and aromatics.
