US Classification:

60274, 60282

Abstract:

Methods and systems are provided for selective catalytic reduction of NOx with a low molecular low molecular weight aldehyde, e.g., acetaldehyde, as a reductant using a catalyst system including two catalysts. An exhaust stream containing an amount of NO from a combustion operation is provided. A portion of the exhaust stream is introduced to a first catalyst to convert the NO to NO. The exhaust stream from the first catalyst with NOand a reductant stream containing a low molecular weight aldehyde, e.g., acetaldehyde, are introduced to the second catalyst to convert the NOto N. The first catalyst can be bulk CoO, Ru or Pt loaded on alumina; the second catalyst can be various zeolites, or zeolites loaded with potassium.

International Classification:

C10G 67/06
C10M 105/00
G01N 21/64

Abstract:

Systems and methods are provided to allow for characterization of feeds, intermediate effluents, and/or products during lubricant base stock production. More generally, the systems and methods can allow for characterization of aromatics in various types of hydroprocessed intermediate effluents and/or products. In some aspects, the characterization can include measuring a fluorescence excitation-emission matrix spectrum for a sample, and then generating a representation of the spectrum by fitting the measured spectrum to a linear combination of spectra corresponding to compounds or compound classes. As the hydroprocessing process continues, additional measured spectra and comparing the fit quality of the representation to the subsequently measured spectra. When the fit quality falls below a threshold value, the loss in fit quality indicates a change in the number and/or distribution of aromatics in the sample. In other aspects, fluorescence excitation-emission spectroscopy can be used to characterize the amount of aromatics within a sample that correspond to one or more fluorescence compound classes. Based on this characterization, adjustments can be made to a process to reduce undesirable levels of aromatics, such as undesirable levels of polynuclear aromatics.

C10G 53/02
B03C 5/00
B03C 5/02

Abstract:

A method includes introducing a crude oil process stream into an electro-kinetic separator (EKS), passing the crude oil process stream through an electric field generated by the EKS, and removing at least a portion of salt and solid particles from the crude oil process stream as the crude oil process stream passes through the electric field. A product stream is discharged from the EKS with reduced salt and solid particle count as compared to the crude oil process stream.

International Classification:

C10G 67/04
C10G 21/00
C10G 67/06

Abstract:

Adsorbents for aromatic adsorption are used to improve one or more properties of base stocks derived from deasphalted oil fractions. The adsorbents can allow for removal of polynuclear aromatics from an intermediate effluent or final effluent during base stock production. Removal of polynuclear aromatics can be beneficial for improving the color of heavy neutral base stocks and/or reducing the turbidity of bright stocks.

International Classification:

B01D 17/00

Abstract:

Systems and methods are provided for performing field enhanced separations on a feed, such as a petroleum feed, a refinery feed, or another type of hydrocarbonaceous feed. The system can allow for increased throughput of feed per volume of the separation device or system while performing a desired amount of field enhanced separation. The field enhanced separation can include separation by thermal diffusion, optionally enhanced by the presence of an electric field in the channel for performing the separation by thermal diffusion.

International Classification:

C10G 65/12

US Classification:

208 89, 208295, 208 97

Abstract:

Systems and methods are provided for using field enhanced separations to produce multiple fractions from a petroleum input. A liquid thermal diffusion and/or electric field separation is used to produce the fractions. The fractions can then be used to form multiple outputs that share a first feature while being different with regard to a second feature. For example, a first fraction from the plurality of fractions can have a desired value for a first property such as viscosity index. Two or more additional fractions from the plurality of fractions can then be blended together to make a blended fraction or output. The blended fraction can have a value for the first property that is substantially similar to the value for the first fraction. However, for a second property, the first fraction and the blended fraction can have distinct values. As a result, multiple output fractions can be formed that share a first feature but differ in a second feature.
