Abstract
Improvements in the commercial viability of oxygen transfer agents (OTAs) and/or catalysts associated with the OCM and the ODH of hydrocarbons to olefins through enhancement of one or more of the selectivity, yield, rate and lifetime of the OTA and/or catalyst is described by one or more of (i) exposing the OTA or the catalyst to a sulfur-containing compound at a site or at a time that is different from where and when the saturated hydrocarbon is converted by the OTA or the catalyst to an unsaturated hydrocarbon; (ii) increasing the particle density of the OTA or the catalyst by treating the OTA or the catalyst with a reducing agent at a site different from where the saturated hydrocarbon is converted by the OTA or by the catalyst to an unsaturated hydrocarbon; and (iii) removing non-selective redox oxygen (NSRO) present on the OTA by subjecting the OTA to a gas that is substantially free of any molecular oxygen.
