Latest Patents

One of Andrews' latest patents is titled "Fluid cracking catalyst and method of making same from waste catalyst." This invention presents an improved process for ion-exchanging sodium ions in particles containing sodium form zeolite crystals and sodium silicate. The method involves an initial ion-exchange at a pH of about 4.5 to 5.0 with an ammonium salt, followed by a second exchange with an ammonium salt at a lower pH of about 2.0 to 3.5. This innovative process results in cracking catalysts that exhibit improved cracking activity. Another significant patent by Andrews is also titled "Fluid cracking catalyst and method of making same from waste catalyst." This invention addresses the recovery of co-product fines from the manufacture of zeolitic cracking catalysts from microspheres of calcined clay, which were previously discarded as waste. The fines are recovered as a moist cake, slurried in a sodium silicate solution, and spray dried to form microspheres. The ion-exchange process, conducted initially at high pH and then at lower pH, produces attrition-resistant cracking catalysts that generate low levels of coke during use.
