Patents by Inventor Timothy K. McNiff

Timothy K. McNiff has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Catalyst composition
    Patent number: 4914074
    Abstract: A novel catalyst composition which comprises alumina and platinum, is characterized in that the alumina carries internally and/or on its surface, gallium and a Group II metal. The catalyst composition is particularly useful in catalytic reforming of hydrocarbon feestocks.
    Type: Grant
    Filed: November 3, 1988
    Date of Patent: April 3, 1990
    Assignee: The British Petroleum Company p.l.c.
    Inventor: Timothy K. McNiff
  • Process for the production of spherical particles
    Patent number: 4894189
    Abstract: A method for making spherical particles, which includes:(a) kneading powdered raw material, preferably a refractory inorganic material, liquid and wax to form a dough/agglomerated granules,(b) separating, preferably by sieving, the dough/agglomerated granules to a predetermined size fraction without extruding, and(c) spheridizing the granules in a heated rotating bowl.The method is particularly useful for the production of catalysts from refractory inorganic materials.
    Type: Grant

    Date of Patent: January 16, 1990
    Assignee: The British Petroleum Company p.l.c.
    Inventors: Dilip Dave, Andrew Holt, Timothy K. McNiff
  • Production of aromatics from hydrocarbon feedstock
    Patent number: 4727206
    Abstract: This invention relates to the aromatization of methane rich hydrocarbon feedstock by contact with a gallium loaded zeolite containing a Group VIIB metal or metal compound as catalyst. The preferred metal is rhenium. The reaction proceeds at a temperature between 600.degree.-800.degree. C. in the absence of oxygen. The reaction products are useful as gasoline blending components.
    Type: Grant
    Filed: December 5, 1986
    Date of Patent: February 23, 1988
    Assignee: British Petroleum Company p.l.c.
    Inventors: David M. Clayson, Timothy K. McNiff
  • Selective dealumination of zeolites
    Patent number: 4654316
    Abstract: This invention relates to a process for selective dealumination, particularly surface dealumination of zeolites by sequential ion-exchange and calcination. The process is selective in the sense that the aluminium atoms within the pore structure of the zeolite remain virtually intact.The surface dealuminated zeolites can be used, after loading with a gallium compound, as catalysts in hydrocarbon conversion reactions.
    Type: Grant
    Filed: August 2, 1985
    Date of Patent: March 31, 1987
    Assignee: The British Petroleum Company p.l.c.
    Inventors: Sami A. I. Barri, Timothy K. McNiff

  • Production of aromatics from ethane and/or ethylene
    Patent number: 4642403
    Abstract: This invention relates to a process for producing aromatic hydrocarbons by bringing a feedback containing at least 10% w/w of C.sub.2 hydrocarbons into contact with a catalyst composition comprising a gallium loaded ziolite and a Group VIII metal selected from rhodium and platinum. The reaction is carried out at a temperature from 500.degree.-750.degree. C. A WHSV of 0.2-10 and a pressure of 1-20 bar are preferred. The presence of Group VIII metal increases conversion of the C.sub.2 feed reduces formation of undesirable polynuclear aromatics.
