Simultaneous processing of catalytic and thermally cracked middle distillate for petrochemical feedstock
The present invention discloses an integrated process scheme for producing (i) high-octane gasoline blending stream (ii) high aromatic heavy naphtha stream which is a suitable feedstock for benzene, toluene, and xylene (BTX) production and (iii) high cetane ultra-low sulphur diesel (ULSD) stream suitable for blending in refinery diesel pool.
PRODUCTION OF LOW CLOUD POINT DISTILLATE FUELS
Systems and methods are provided for catalytically dewaxing a diesel boiling range feed. In some aspects, catalytic dewaxing can be performed at low hydrogen treat gas rates and/or low hydrogen purity conditions. In other aspects, the systems and methods can allow for distillate dewaxing while reducing or minimizing the amount of equipment required.
Multi-Stage Device and Process for Production of a Low Sulfur Heavy Marine Fuel Oil
A multi-stage process for the production of an ISO 8217 compliant Product Heavy Marine Fuel Oil from ISO 8217 compliant Feedstock Heavy Marine Fuel Oil involving a Reaction System composed of one or more reactor vessels selected from a group reactor wherein said one or more reactor vessels contains one or more reaction sections configured to promote the transformation of the Feedstock Heavy Marine Fuel Oil to the Product Heavy Marine Fuel Oil. The Product Heavy Marine Fuel Oil has a Environmental Contaminate level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 mass % to 1.0 mass. A process plant for conducting the process for conducting the process is disclosed that can utilize a modular reactor vessel.
Configuration for olefins production
Processes herein may be used to thermally crack various hydrocarbon feeds, and may eliminate the refinery altogether while making the crude to chemicals process very flexible in terms of crude. In embodiments herein, crude is progressively separated into at least light and heavy fractions. Depending on the quality of the light and heavy fractions, these are routed to one of three upgrading operations, including a fixed bed hydroconversion unit, a fluidized catalytic conversion unit, or a residue hydrocracking unit that may utilize an ebullated bed reactor. Products from the upgrading operations may be used as feed to a steam cracker.
Process and Materials for Trim Dewaxing of Distillates
Described herein are novel and inventive dewaxing processes that employ dewaxing catalysts which are co-extrusions of two different zeolites, particularly two different 10MR zeolites or a co-extrusion of a 10MR zeolite and a 12MR zeolite in combination with a hydrogenation component. The hydrogenation component can be a mixture of non-noble metal components or a mixture of noble metal components. This novel and inventive process demonstrated a significant activity boost (as measured by increased cloud point reduction) and/or selectivity boost (as measured by reduced diesel loss) compared to either single zeolite component.
Environment-friendly marine fuel
For the shipping industry, these fuels provide solutions to long outstanding technical problems that heretofore hindered supply of low sulfur marine fuels in quantities needed to meet worldwide sulfur reduction goals. When ships on the open seas burn cheap low grade heavy bunker oils high in sulfur, nitrogen and metals, the SOx, NOx, and metal oxides go to the environment. This invention converts essentially all of each barrel of crude feed to a single ultraclean fuel versus conventional refining where crude feed is cut into many pieces, and each piece is sent down a separate market path meeting various different product specifications. When in port, ships can generate and sell electricity to land based electrical grids to offset fuel cost in an environment-friendly manner.
Preparation of a fuel blend
A method is disclosed for preparing a renewable fuel blend. The method includes subjecting at least two feedstocks of different biological origins to catalytic cracking in a catalytic cracking unit and to hydrotreatment in a hydrotreatment unit to form a fuel blend having an aromatic hydrocarbon content from 26 to 42 wt-% and a paraffinic hydrocarbon content of less than 53 wt-%, as measured according to ASTM D2425-04 (2011). The fuel blend is formed by mixing the at least two feedstocks together before subjecting them to the catalytic cracking and hydrotreatment, or by obtaining a first fuel component and at least one further fuel component from the catalytic cracking and hydrotreatment of the at least two feedstocks, and mixing the first fuel component and the at least one further fuel component together.
Process for deparaffinning a middle distillate feedstock using a catalyst based on IZM-2 zeolite and an MFI-type zeolite
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.
PROCESS AND DEVICE FOR REDUCING ENVIRONMENTAL CONTAMINATES IN HEAVY MARINE FUEL OIL
A process for reducing the environmental contaminants in a ISO 8217 compliant Feedstock Heavy Marine Fuel Oil, the process involving: mixing a quantity of the Feedstock Heavy Marine Fuel Oil with a quantity of Activating Gas mixture to give a feedstock mixture; contacting the feedstock mixture with one or more catalysts to form a Process Mixture from the feedstock mixture; separating the Product Heavy Marine Fuel Oil liquid components of the Process Mixture from the gaseous components and by-product hydrocarbon components of the Process Mixture and, discharging the Product Heavy Marine Fuel Oil. The Product Heavy Marine Fuel Oil is compliant with ISO 8217 for residual marine fuel oils and has a sulfur level has a maximum sulfur content (ISO 14596 or ISO 8754) between the range of 0.05 % wt. to 0.5 % wt.. The Product Heavy Marine Fuel Oil can be used as or as a blending stock for an ISO 8217 compliant, IMO MARPOL Annex VI (revised) compliant low sulfur or ultralow sulfur heavy marine fuel oil. A device for conducting the process is also disclosed.
