摘要:
Waxy feeds are converted to a basestock using a unitized mixed powdered pellet catalyst comprising a metal hydrogenation component on a support having a frist dewaxing component and a second isomerization component, wherein the first component is selected from 10 and 12 ring molecular sieves and mixtures thereof and the second component is an amorphous inorganic oxide. The first and second components are present in a ratio sufficient to promote wax isomerization and naphthene distractions without substantial decrease in VI.
摘要:
A method for hydroisomerizing a waxy feed to favor one of VI or yield is described. The method uses a unitized pellet powder catalyst comprising a metal hydrogeneration component, a first catalytic component selected from 8, 10 and 12 ring moleular sieves and mixtures thereof, and a second amorphous isomerization component which is an amorphous inorganic oxide. Importantly, the ratio of feed and second components are present in a predetermined ratio to provide a preselected acidity favoring one of VI or yield resulting from the hydroisomerization.

摘要:
A process for producing lube oil basestocks wherein a wax containing lube oil boiling range feedstream is converted into a basestock suitable for use in motor oil applications by contacting it with a hydrodewaxing catalyst containing a medium pore molecular sieve having deposited thereon an active metal oxide and at least one hydrogenation metal selected from the Group VIII and Group VIB metals.
摘要:
A process for preparing high VI lubricating oil basestocks comprising hydrotreating, hydrodewaxing and optionally hydrofinishing. The hydrotreated feedstock is hydrodewaxed using a dewaxing catalyst that has been selectively activated by oxygenate treatment. The hydrodewaxed product may then be hydrofinished.
摘要:
A dewaxing catalyst is selectively activated by treatment with an oxygenate. Selective activation is accomplished by treated the dewaxing catalyst with a carrier feed containing oxygenate. The selectively activated dewaxing catalyst when used to dewax waxy hydrocarbons results in improved yield of isomerate at equivalent pour point over a dewaxing catalyst which has not been oxygenate treated.

摘要:
This invention relates to a method for upgrading petroleum streams which have been treated with peroxide, extracted to remove oxidized sulfur and nitrogen compounds, dewaxed and hydrofinished. More particularly, peroxides are generated in-situ by combining the petroleum stream with a high neutralization number (HNN) crude and adding an oxygen-containing stream. Alternatively, the oxidation of sulfur and nitrogen compounds may be accomplished by adding peroxides in the presence of oil soluble metal catalysts. The peroxides oxidize nitrogen and sulfur compounds in the petroleum stream to more polar compounds which are solvent extracted.
摘要:
A method comprises receiving first video data at a source end, the first video data including video data relating to an event of interest captured using a video camera disposed at the source end. The first video data is retrievably stored in a memory storage device. Video analytics is performed on the first video data to identify a first portion of the first video data that is representative of the event of interest. Subsequently, portions of the first video data other than the first portion are deleted from the memory storage device.
摘要:
A method comprises transmitting video data from a source end to a central server via a Wide Area Network (WAN). The video data includes video data relating to an event of interest, and is captured using a video camera disposed at the source end. Via a plurality of streams, the video data is transmitted from the central server to each one of a plurality of different video analytics engines. Different video analytics processing of the video data is performed using each one of the plurality of different video analytics engines.
