Abstract: The present invention is devoted to an analytical method for directly determining carbon number and molecular weight distributions of isoparaffin mixtures. The analytical means uses low in-scan emitter-current field-ionization mass spectroscopy to substantially reduced or eliminated molecular ion fragmentation for isoparaffins, which allows direct measurement of isoparaffin molecular ions for their distributions. The analytical means is capable of directly characterizing isobutane to C50+ isoparaffins, covering naphtha to gas oil ranges.

Abstract: A process for providing distillate products which are substantially sulfur free, which process comprises subjecting a distillate stream to conventional hydrodesulfurization conditions including a catalyst comprised of a Group VI metal and at least one Group VIII metal on a refractory support. The hydrodesulfurized stream is then treated with a solid adsorbent material capable of adsorbing beta and di-beta-substituted dibenzothiophene sulfur compounds.
