Abstract

High aromatics content in distillate fuels is undesirable since it lowers the fuel quality and contributes to the formation of environmentally harmful emissions, such as particulate matter and NOx. A fixed-bed flow reactor system was used for the hydrogenation of tetralin to decalins in the presence of benzothiophene, as a model reaction for the saturation of aromatics in diesel feedstocks. Several noble-metal catalysts were prepared on various supports, including alumina, titania, Y-zeolite, mordenite zeolite, and HZSM-5 zeolite. Y-zeolite supported catalysts exhibited higher sulfur tolerance than any of the other catalysts tested. As the activity of the catalysts decreased as a result of sulfur poisoning, the selectivity to trans-decalin also decreased, while the selectivity to cis-decalin increased. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA 8/22-26/2004).
