  • Patent number: 10780430
    Abstract: Methods are provided for forming noble metal catalysts comprising both platinum and a second Group VIII metal, such as palladium, with improved aromatic saturation activity. Instead of impregnating a catalyst with both platinum and another Group VIII metal at the same time, a sequential impregnation can be used, with the Group VIII metal being impregnated prior to platinum. It has been discovered that by forming a Group VIII metal-impregnated catalyst first, and then impregnating with platinum, the distribution of platinum throughout the catalyst can be improved. The improved distribution of platinum can result in a catalyst with enhanced aromatic saturation activity relative to a catalyst with a similar composition formed by simultaneous impregnation.

  • Patent number: 10774268
    Abstract: Techniques described herein relate to producing bitumen while monitoring various aspects of paraffinic froth treatment (PFT) operations using near infrared (NIR) spectrometry and chemometric analysis to continuously monitor and enable measurements of physical and chemical properties of various streams in PFT operations, which can be done in real time online and can facilitate process control. NIR spectrometry can be used to acquire NIR spectra measurements from a PFT process stream and the NIR spectra measurements and chemometric analysis can, in turn, be used to determine composition characteristics of the PFT process stream as well as operational features of a PFT process unit. For example, NIR spectra can be used to determine upward velocity in a PFT settler to facilitate settler operation for diluted bitumen quality control. NIR spectra can be obtained using reflectance or transmission probes which can be positioned within particular phase of a stratified PFT process stream.

  • Patent number: 10752846
    Abstract: Systems and methods are provided for improving the processing of heavy or challenged feeds in a refinery based on integrated use of deasphalting, coking, and hydroprocessing. An optional fluid catalytic cracking unit can be included in the integrated system to allow for further improvements. The improved processing can be facilitated based on a process configuration where the vacuum resid fractions and/or other difficult fractions are deasphalted to generate a deasphalted oil and a deasphalter residue or rock fraction. The deasphalted oil can be passed into a hydroprocessing unit for further processing. The rock fraction can be used as the feed to a coking unit. Although deasphalter residue or rock is typically a feed with a high content of micro carbon residue, a high lift deasphalting process can allow a portion of the micro carbon residue in the initial feed to remain with the deasphalted oil.
