  • Publication number: 20240047010
    Abstract: A method is provided for determining a sample genome from a plurality of read fragments and a reference genome. The method includes: (i) applying a first putative variant event, selected from a set of candidate variant events, to the sample genome to update the sample genome; (ii) mapping the plurality of read fragments to the updated sample genome; (hi) based on the mapping of the plurality of read fragments to the updated sample genome, determining a first read mapping cost function; and (iv) based on the first read mapping cost function, retaining the updated sample genome and removing the first putative variant event from the set of candidate variant events.

  • Patent number: 9546327
    Abstract: A process and catalyst that provides for the upgrading of a high endpoint gas oil feedstock that contains significant concentrations of organic sulfur compound and organic nitrogen compounds. Included among the sulfur compounds are the dimethyl-dibenzothiophenes and derivative thereof. The catalyst of the process is an additive impregnated composition or a derivative thereof that further comprises cobalt and molybdenum. The process provides for the upgrading the high endpoint gas oil feedstock by significantly reducing the difficult to remove thiophene and nitrogen compounds and the process does this with a significantly reduced hydrogen consumption relative to processes using comparative catalysts.

  • Patent number: 9404053
    Abstract: A low-pressure process for hydrodenitrogenation and hydrodesulfurization of a gas oil feedstock. The process uses a multi-bed, stacked-bed reactor system. The first and third beds of the multi-bed, stacked-bed reactor system include catalysts that comprise cobalt and molybdenum supported on alumina. The middle, second bed, includes a catalyst comprising nickel and molybdenum supported on alumina that preferably includes an additive. The stacked bed arrangement with the use of the specific catalysts provides for the low-pressure operation and significantly improved HDN and HDS activity with relatively insignificant differences in hydrogen consumption.
