Provided is a system to upgrade an input stream of a straight run vacuum residue or a cracked feedstock that includes a vacuum column, a hydrocracking unit, a high lift solvent deasphalting unit, a low lift solvent deasphalting unit, and a bitumen blowing unit or a pitch pelletizing unit, and optionally a hydrotreating reactor. The system and components thereof may pass a distillate and naphtha product, a light ends product, an asphaltene-lean heavy deasphalted oil stream, an asphaltene-rich pitch stream, a light deasphalted oil that is a lube base feed stock, a heavy oil stream, a bitumen and asphalt stream or a solid fuel. Further provided is a process, including introducing a straight run vacuum residue or a cracked feed stock into a system, and operating the system including a step of fractionating, a step of solvent stage deasphalting, and a step of hydrocracking.
Hazy-free at 0° C heavy base oil and a process for producing
A process for producing a base oil composition from a deasphalted oil (DAO) feed, where the DAO feed undergoes hydrotreating, hydrocracking, catalytically dewaxing, hydrofinishing, and fractionating to generate the base oil composition. The base oil composition includes a hazy-free at 0° C. heavy base oil comprising (a) a kinetic viscosity ranging from 15 to 21 cSt at 100° C., (b) a 5 viscosity index of at least 95, (c) a pour point of less than −12° C., (d) a cloud point of less than −18° C., and (e) a total aromatics content of 2 wt % or less, where the hazy-free at 0° C. heavy base oil maintains a hazy-free appearance when stored undisturbed at 0° C. during a test period.
NEW POLYOLEFIN CATALYST AND USE THEREOF
Disclosed is a new polyolefin catalyst and preparation therefor. Specifically, disclosed is a catalytic system comprising a new complex of iron, cobalt, nickel, palladium, and platinum. In the presence of the catalytic system, oily polyethylene can be efficiently obtained from simple olefins such as ethylene under mild conditions, highly branched oily alkane mixture is then obtained after hydrogenation. The alkane mixture can be used as a processing aid and a high-performance lubricant base oil. The present invention also provides a method for preparing the catalyst, a method for preparing the highly branched oily alkane mixture and a method for preparing functional polyolefin oil.
HIGH PERFORMANCE PROCESS OIL BASED ON DISTILLED AROMATIC EXTRACTS
Naphthenic process oils are made by blending one or more naphthenic vacuum gas oils in one or more viscosity ranges with a high C.sub.A content distilled aromatic extract feedstock to provide at least one blended oil, and hydrotreating the at least one blended oil to provide an enhanced C.sub.A content naphthenic process oil. The order of the vacuum distillation and blending steps may be reversed.
Composition comprising paraffins and method for producing the same
The invention relates to a composition comprising C10-C20 paraffins, wherein about 3 wt. % to about 30 wt. %, based on the total weight of the composition, are C10-C15 paraffins, and the C10-C20 paraffins are derived from a biological raw material. The invention also relates to a protective agent for a porous material, comprising said composition.

The Product Heavy Marine Fuel Oil is compliant with ISO 821 7 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.
Hydrocracking process for high yields of high quality lube products
A process for producing high yields of higher quality (API Group II, Group III′) lubricating oil basestock fractions which allows the production of two or more types of high quality lubes in continuous mode (no blocked operation mode) without transition times and feed or intermediate product tankage segregation. Two consecutive hydroprocessing steps are used: the first step processes a wide cut feed at a severity needed to match heavy oil lube properties. The second step hydroprocesses a light oil after fractionation of the liquid product from the first step at a severity higher than for the heavy oil fraction. The two hydroprocessing steps will normally be carried out in separate reactors but they may be combined in a single reactor which allows for the two fractions to be processed with different degrees of severity.
CONFIGURATION FOR OLEFINS AND AROMATICS 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.
