Isomerization of normal paraffins to form branched paraffins may be complicated by significant cracking of Cparaffins under isomerization reaction conditions. This issue may complicate upgrading of hydrocarbon feeds having significant quantities of heavier normal paraffins. Cracking selectivity may be decreased by combining one or more naphthenic compounds with a feed mixture comprising at least one Cnormal paraffin and/or by utilizing tungstated zirconium catalysts having decreased tungsten loading. Further, Cand Cnormal paraffins may undergo isomerization in the presence of Cnormal paraffins. Methods for isomerizing normal paraffins may comprise: providing a feed mixture comprising at least C-Cnormal paraffins and lacking normal paraffins larger than C; and contacting the feed mixture with a bifunctional mixed metal oxide catalyst under isomerization reaction conditions effective to form a product mixture comprising one or more branched paraffins formed from each of the C-Cnormal paraffins.

Compositions based on effluents and/or products from FCC processing of a high saturate content, low heteroatom content feedstock are provided. By processing a high saturate content, low heteroatom content feed under various types of FCC conditions, a variety of compositions with unexpected compositional features and/or unexpected properties can be formed. The unexpected compositional features and/or unexpected properties can correspond to features and/or properties associated with one or more of the total effluent, a naphtha boiling range portion of effluent, a distillate or light cycle oil boiling range portion of the effluent, and/or a bottoms portion of the effluent.

Products from FCC processing of high saturates and low heteroatom feeds

Methods of refining a whole crude oil stream. The methods involve first processing the crude either through a hydrotreating reactor comprising a dewaxing reactor bed or a flash evaporation separator. The treated streams are then further processed through a demetalization reactor bed, a hydroprocessing reactor bed, or both. The stream can then be still further processed via additional hydrotreating, distillation, or both.

Methods of whole crude and whole crude wide cut hydrotreating and dewaxing low hetroatom content petroleum

Method of refining whole crude oil or a wide cut crude oil, the methods comprising a combination of a hydrotreating reactor, a distillation tower, and an optional flash evaporation separator. The methods can also include light ends processing, fluid catalytic cracking, reforming, hydrocracking, and demetalization. In some methods a whole crude oil is first processed through a flash evaporation separator to create a wide cut crude oil and in other methods, the flash evaporation separator is not used as the whole crude oil is first treated in a hydrotreater.

Distillate boiling range and/or diesel 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. This unexpected combination of properties is characteristic of crude oils that can be fractionated to form distillate/diesel boiling range compositions that can be used as fuels/fuel blending products with reduced or minimized processing. The resulting distillate boiling range fractions and/or diesel boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight and/or volume ratio, a low but substantial aromatics content, and a low sulfur content. 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.
