  • Process and composition for preparation of cracking catalyst suitable for enhancing LPG
    Patent number: 10449524
    Abstract: The present invention relates to a catalyst product for cracking of heavy hydrocarbon feed stocks predominantly in to light olefins and processes for preparing the catalyst. More specifically the present invention relates to a process of preparing Fluidic Catalytic Cracking (FCC) catalyst additive composition. The FCC catalyst additive composition of the present invention is a LPG selective catalyst particles comprising a medium pore zeolite bonded with clay-phosphate-silica-alumina binder. The catalyst of the present invention exhibits improved selectivity towards high value components like propylene and gasoline and suppressing low value components like dry gas and bottoms.

  • Adsorbent composition for removal of refractory sulphur compounds from refinery streams and process thereof
    Publication number: 20070023325
    Abstract: The present invention relates to a adsorbent composition for removing refractory sulphur compounds from refinery streams comprising of base component in the range of 10 to 50 wt %, spinel oxide in the range of 20 to 60 wt % as a reactive metal oxide component and bimetallic alloy in the range of 10 to 40 wt % acting as an adsorption enhancer component, wherein the adsorption enhancer component acts in synergy with base component. The invention also relates to a process for the preparation of said composition by mixing in solid state fine particles of base component, spinel oxide and bimetallic alloy, homogenizing the mixture thus obtained with solvent, peptizing the wet solid with dilute mineral acid, extruding the peptized material with extrusion aiding agents, drying the extrudates, further calcining the dried extrudates and reducing the calcined material under hydrogen flow.
