  • GENETIC ANALYSIS METHOD
    Publication number: 20210134390
    Abstract: A method of target DNA genome analysis is provided. The method comprises the steps of: —obtaining non-overlapping segments of target DNA stretches with segment boundaries defined by the presence of particular restriction enzyme recognition sites, whereby the assembly of said non-overlapping segments compose a reduced representation library of said target DNA genome; —obtaining for said segments, raw metrics from a sequencing process applied on said reduced representation library; —clustering non-overlapping, nearby segments with similar raw metrics to provide master segments; —providing metrics describing the master segments, —making a final discrete DNA call based on the master segments and its metrics.
    Type: Application

  • Catalyst having a zeolitic core and zeolitic layer and the use of the catalyst for olefin oligomerization
    Patent number: 6300536
    Abstract: A molecular sieve comprising a core having deposited thereon a surface layer, wherein the core is a zeolite containing silicon and at least one element selected from gallium and iron and the surface layer has a higher Si:Al ratio than that of the silicon:selected element ratio of the core, provides for lower branching in olefin oligomerization products.
    Type: Grant
    Filed: November 8, 1999
    Date of Patent: October 9, 2001
    Assignee: Exxon Mobil Chemical Patents, Inc.
    Inventors: Wim Herman Verrelst, Luc Roger Marc Martens, Johannes Petrus Verduijn
  • Oligomerization and catalysts therefor
    Patent number: 6143942
    Abstract: Oligomerization degree of olefins may be controlled by employing mixed molecular sieve catalysts. Propene may be trimerized to nonene using ZSM-5 and ZSM-22, especially in an extrudate admixture.
    Type: Grant
    Filed: October 22, 1996
    Date of Patent: November 7, 2000

  • Hydrocarbon treatment
    Patent number: 5874661
    Abstract: The average degree of branching of a branched olefin feedstock is reduced by skeletal isomerization in contact with a molecular sieve.
