Abstract
Naphtha boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. The resulting naphtha boiling range fractions can have a high naphthenes to aromatics weight ratio, a low but substantial content of aromatics, and a low sulfur content. In some aspects, the fractions can be used as fuels and/or fuel blending products after fractionation with minimal further refinery processing. In other aspects, the amount of additional refinery processing, such as hydrotreatment, catalytic reforming and/or isomerization, can be reduced or minimized. By reducing, minimizing, or avoiding the amount of hydroprocessing needed to meet fuel and/or fuel blending product specifications, the fractions derived from the high naphthenes to aromatics ratio and low sulfur crudes can provide fuels and/or fuel blending products having a reduced or minimized carbon intensity.
