Abstract: The present invention relates to a stabilized inorganic oxide support for capturing carbon dioxide from gases having high regeneration capacities over many cycles. The method for preparing the stabilized inorganic oxide support includes stabilizing an alumina-containing precursor by either calcining or steaming, impregnating an alkali or alkaline earth compound into the stabilized alumina-and drying the alkali or alkaline earth compound-impregnated stabilized alumina-. The stabilized inorganic oxide support can be regenerated at lower temperatures between 100 and 150° C. The carbon dioxide adsorption capacity of the regenerated support is between 70 and 90% of the theoretical carbon dioxide adsorption capacity.

Abstract: An improved process for the catalytic gasification of a carbonaceous feedstock in a dual fluidized bed reactor for producing synthesis gas is disclosed. The disclosure uses γ-alumina as a catalyst support iand heat carrier in the gasification zone (102). The gasification zone (102) is operated at 700-750° C. to prevent substantial conversion of γ-alumina to α-alumina, which would manifest in the enablement of high catalyst loading and high recyclability. The catalyst is an alkali metal, preferably K2CO3, so that conversion proportional to total K2CO3 to solid carbon ratio is achieved with as high K2CO3 loading as 50 wt % on the solid support. The combustion zone (140) is operated at 800°-840° C., to prevent any conversion of the γ-alumina to α-alumina, so that catalyst recyclability of up to 98% is achieved between two successive cycles.

Abstract translation: 公开了用于生产合成气的双流化床反应器中碳质原料的催化气化的改进方法。 本公开使用γ-氧化铝作为气化区（102）中的催化剂载体和热载体。 气化区（102）在700-750℃下运行，以防止γ-氧化铝大量转化成α-氧化铝，这表明在高催化剂负载和高可回收性方面。 催化剂是碱金属，优选为K 2 CO 3，因此与固体载体上的重量比为50重量％的高的K 2 CO 3负载相比，实现了与总的K 2 CO 3成比例的转化率与固体碳的比例。 燃烧区（140）在800°-840℃下运行，以防止γ-氧化铝转化为α-氧化铝，从而在两个连续循环之间实现高达98％的催化剂可再循环。

Abstract: The present disclosure relates to a hydrothermally stable catalyst composition. The hydrothermally stable supported catalyst composition comprises K2CO3 impregnated on an amorphous silica-alumina support. The weight ratio of silica to alumina in the support is in the range of 0.1 to 1.5. The amount of K2CO3 is in the range of 5 wt % to 60 wt % with respect to the total catalyst composition. The catalyst composition is characterized by a pore volume in the range of 0.1 cc/g to 0.9 cc/g, a surface area in the range of 40 m2/g to 250 m2/g and an attrition index in the range of 2% to 8%. The present disclosure also relates to a process for preparing the catalyst composition. The catalyst composition provides improved hydrothermal stability, attrition resistance, high pore volume and surface area for gasifying carbonaceous feed at low temperature, as compared to a conventional catalyst composition.

Abstract: A process for obtaining vanadium component in the form of vanadium oxide from gasifier slag is disclosed. The process comprises pulverizing the slag to obtain pulverized slag, which is blended with water and an alkali salt to obtain a slurry. The slurry is dried and then roasted in the presence of air to obtain a roasted slag. The roasted slag is leached to obtain a first filtrate comprising the vanadium component. The first filtrate is reacted with a magnesium salt to remove a silica component in the form of a precipitate. The silica free second filtrate is reacted with an ammonium salt to obtain ammonium metavanadate, which is further calcined to obtain the significant amount of vanadium pentoxide (V2O5).

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.
