The present disclosure includes a system for producing low carbon olefins and/or aromatics from raw material comprising naphtha. The system can include a reaction unit that includes a fast fluidized bed reactor, a stripping unit that includes a stripper, and a regeneration unit. The reactor unit is adapted to allow the catalytic cracking of naphtha and to output reaction unit effluent material (spent catalyst and product gas) into the stripping unit, which is adapted to output product gas. The stripping unit is connected to and in fluid communication with the regeneration unit such that the stripping unit supplies the spent catalyst from the reaction unit to regeneration unit. The regeneration unit is adapted to regenerate the spent catalyst to form regenerated catalyst. The regeneration unit is connected to and in fluid communication with the fast fluidized bed reactor such that, in operation, regenerated catalyst can be sent to the fast fluidized bed reactor of the reaction unit.

This disclosure relates to methods of upgrading hydrocarbon feed stream, which can include separating the hydrocarbon feed stream into a heavy fraction and a light fraction, hydrotreating an aromatic feed stream with at least a first catalyst in a first reactor comprising hydrogen to produce a first product effluent, combining the heavy fraction with at least a portion of the first product effluent to form a mixed stream, and hydrotreating the mixed stream with one or more second catalysts in a second reactor comprising hydrogen to produce a second product effluent.

The present invention is based on the use of a two-step hydrocracking process for the production of naphtha, comprising a step of hydrogenation placed downstream of the second hydrocracking step, the hydrogenation step treating the effluent resulting from the second hydrocracking step in the presence of a specific hydrogenation catalyst. Furthermore, the hydrogenation step and the second hydrocracking step are performed under specific operating conditions and in particular under quite specific temperature conditions.

The present invention relates to a process for deparaffinning a middle distillate feedstock, to convert, in good yield, feedstocks having high pour points into at least one cut having an improved pour point.

Said process is performed with at least one catalyst comprising at least one hydro-dehydrogenating phase containing at least one metal from group VIB and at least one metal from group VIII of the Periodic Table of the Elements, and a support comprising at least one IZM-2 zeolite, a zeolite of WI framework type code and at least one binder.

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.

The process may include separating the hydrocarbon material into at least a lesser boiling point fraction and a greater boiling point fraction, cracking at least a portion of the greater boiling point fraction in the presence of a first catalyst in an environment comprising less than 0.1 mol. % water to produce a first cracking reaction product, combining steam with the lesser boiling point fraction upstream of the cracking of the lesser boiling point fraction, cracking at least a portion of the lesser boiling point fraction in the presence of a second catalyst to produce a second cracking reaction product, and separating the petrochemical products from one or both of the first cracking reaction product or the second cracking reaction product.

According to one or more embodiments, presently disclosed are processes for producing petrochemical products from a hydrocarbon material. The process may include separating the crude oil into at least a lesser boiling point fraction and a greater boiling point fraction. At least 90 wt. % of the crude oil may be present in the combination of the greater boiling point fraction and the lesser boiling point fraction.
