ABSTRACT:

During this period, work was continued on understanding the attrition of precipitated iron catalysts and work initiated on synthesizing catalysts containing silica binders. Use of a sedigraph particle size analyzer with an ultrasonic probe provides a simple method to test the strength of catalyst agglomerates, allowing the strength comparison of silica and hematite catalysts (the former is considerably stronger). Study of Fe/silica interactions was continued. Addition of a colloidal silica precursor to calcined Fe(sub 2)O(sub 3) catalyst had no detrimental effect on reducibility of the hematite to (alpha)-Fe. XRD and electron microscopy will be used to analyze the crystal structure and types of C present in samples from long Fischer-Tropsch runs.
