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 (KCO) is impregnated thereon to form an adsorbent comprising potassium carbonate (KCO) 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.

The present invention relates to a catalyst composition for Fluid Catalytic Cracking (FCC) which contains a combination of a FCC catalyst component and an additive component with certain physical properties attributed therein. The present invention is also directed to provide methods for the preparation of the catalyst composition for FCC. The admixture of the FCC catalyst component and additive component is used in cracking of hydrocarbon feedstock containing hydrocarbons of higher molecular weight and higher boiling point and/or olefin gasoline naphtha feedstock for producing lower yield of fuel gas without affecting the conversion and yield of general cracking products such as gasoline, propylene and Colefins.
