ABSTRACT:

In this quarter, we studied the effect of hydrogen pressure, and of sulfur and nitrogen containing compounds on the isomerization and hydrocracking of n-hexadecane using a Pt/ZrO2/SO4 catalyst. The reactions were carried out at 300 deg C and hydrogen pressures between 50 and 500 psig. Increasing hydrogen pressure resulted in increased conversion and increased hydrocracking. Nitrogen containing compounds had a greater inhibiting effect on the conversion of n-hexadecane than sulfur-containing compounds. The reaction of diphenylmethane in air at 25 deg C and in the presence of sulfated zirconia was studied as a possible means to characterize the protonic acidity of solid superacids.
