Abstract: A process for catalytic conversion of low value hydrocarbon streams to light olefins in comparatively higher yields is disclosed. Propylene is obtained in amounts higher than 20 wt. % and ethylene higher than 6 wt. %. The process is carried out in a preheated cracking reactor having a single riser and circulating an FCC catalyst. The riser is divided into three temperature zones in which different hydrocarbon feeds are introduced. An oxygenate feed is introduced in the operative top zone in the riser. Heat for the endothermic cracking is obtained by the exothermic reaction of converting the oxygenate feed into gas and/or from a regenerator in which the spent FCC catalyst is burnt.

Abstract: A process for testing a zeolite based FCC catalyst and a ZSM-5 zeolite based FCC catalyst additive for simulating commercial plant yields is disclosed in, the present disclosure wherein the catalyst and the additive are subjected separately to a steaming protocol with 60 to 100% steam at a temperature in the range of 750° C. to 850° C. for 3 to 200 hours to obtain a catalyst and a catalyst additive deactivated under, said simulated commercial plant hydrothermal deactivation conditions. The deactivated catalyst and the deactivated catalyst additive are admixed in a pre-determined weight proportion. The obtained catalyst mixture is then used for cracking a hydrocarbon feed for a pre-determined period of time to generate cracking data. Product yields are measured from the generated cracking data at a pre-determined simulated commercial plant conversion of the hydrocarbon feed.

Abstract: The present disclosure relates to a process for capturing carbon-dioxide from a gas stream. In order to capture the carbon-dioxide, a support is provided and potassium carbonate (K2CO3) is impregnated thereon to form an adsorbent comprising potassium carbonate (K2CO3) impregnated support. The adsorbent is activated to form an activated adsorbent. The gas stream is passed through the adsorber to enable adsorption of the carbon-dioxide on the activated adsorbent to form a carbon-dioxide laden adsorbent. The carbon-dioxide laden adsorbent is transferred to a desorber for at least partially desorbing the carbon-dioxide from the carbon-dioxide laden adsorbent by passing a carbon-dioxide deficient stream through the desorber. The partially regenerated adsorbent is returned to the adsorber for adsorbing the carbon-dioxide from the carbon-dioxide. The process of the present disclosure reduces the overall energy demand by partially regenerating the adsorbent.
