Abstract: Wet impregnation of active metal precursors into porous substrates, together with selective adsorption of the precursors on the pore surfaces, enables transition metal oxides derived from the precursors to disperse throughout the substrate, even at the nanoscale, without increased sintering or agglomeration, thereby forming oxygen carriers suitable for chemical looping. The porous substrate can be an oxide, for example SiO2. The oxygen carriers can comprise relatively large oxide loadings of over about 20 wt % and exhibit high reactivity over many regeneration cycles with substantially no loss in oxygen transport capacity or decrease in kinetics. The use of multiple transition metal oxides, for example NiO in addition to CuO, can greatly enhance chemical looping performance.

Abstract: A method of making granular extrudate by extruding a starch-containing admixture from an extruder into an extrudate discharge chamber in gas flow communication with a discharge conduit that transports the granular extrudate away therefrom in gas turbulently flowing therethrough. During transport of the granular extrudate from the discharge chamber and through the conduit in the flowing gas, the gas quenches the granular extrudate cooling and drying the granular extrudate without heating it. Quenching reduces the granular extrudate temperature by at least 15° Celsius and moisture content to no greater than 13%. Quenching prevents shrinkage and densification of the extrudate including when cut into pellets. Quenching also prevents retrogradation, crystallization/recrystallization and solubilization of cold-water soluble binder formed in each pellet during extrusion.
