AMÉLIORATION DE L'EFFICACITÉ DES ADDITIFS FCCU DE RAFFINERIE

摘要

This invention is an improvement to refinery Fluid Catalytic Cracking Unit (FCCU) additives. The improved is obtained through the adjustment of the particle size distributions of the additives. Narrowing the range of particle size distributions for the additives results in improved performance in a wide range of additive compounds. In addition it allows for removal of the additives when combined with cracking catalysts.
