ABSTRACT:
Methods are provided for regenerating a zeolitic molecular sieve having a sulfur-containing carbonaceous material deposited thereon by contacting the zeolitic molecular sieve with an oxygen-containing regeneration feed gas to remove at least a portion of the carbonaceous deposit material and thereafter absorbing sulfur oxides present in the regeneration gas using soda-lime absorbent. The methods can inhibit the deactivation of zeolitic molecular sieves by avoiding contact thereof with the sulfur oxides. In a specific aspect of the present invention, the regeneration method is incorporated into a method for separating normal paraffins from a sulfur-containing hydrocarbon feed in the gas oil or kerosene carbon range.
