Abstract
A process for significantly improving the physical properties of formed particles is disclosed. The process includes adding an effective amount of an acid stable surfactant or an alkaline stable surfactant to a component of the material before drying the particles. The preferred particles are microspheroidal for use in fluid bed reactors, but can include granules and beads.
