Slurry phase iron catalysts for indirect coal liquefaction. Second semi-annual progress report, January 5, 1996--July 4, 1996

PDF Version Also Available for Download.

Description

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 ... continued below
