Application of the Hadamard matrix for factor screening in the elaboration of new semi-synthetic petroleum cracking catalysts
2021
In this study, new semi-synthetic catalysts based on kaolinite were fabricated for catalytic cracking of petroleum residue. A screening study by Hadamard matrix type Plackett and Burman was conducted to determine the factors that influence the development of the best catalysts. The experimentation activated the catalysts with hydrochloric acid (HCl) and then calcined them (650 and 800 °C). The catalytic activity of the catalysts thus elaborated was determined and compared to that of an industrial catalyst. The results indicated values as high as 57 meq/g of acidity on the surface of the elaborated catalysts. The main influencing factors were: kaolinite, acid concentration and the type of oxide used.
