Dale D. Maness 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).

  • Method for treating sulfur dioxide with sorbent
    Patent number: 4152400
    Abstract: Process for preparing shaped base materials for use in solid catalysts for commercial processes. The solid contact material is prepared by pre-soaking a porous solid particulate carrier material in an organic liquid, immersing the carrier without drying in a dilute acid solution for a given time interval, washing, drying and calcining the impregnated carrier. After calcination, the carrier is impregnated with an active material.
    Type: Grant
    Filed: July 26, 1977
    Date of Patent: May 1, 1979
    Assignee: Exxon Research & Engineering Co.
    Inventors: Martin O. Gernand, Dale D. Maness, Neville L. Cull

  • Sorbent preparation and process using same
    Patent number: 4085195
    Abstract: Process for preparing surface impregnated catalysts and sorbents, and flue gas desulfurization process using the same. The sorbent is produced by pre-soaking a porous solid particulate carrier material in a polar organic liquid such as a C.sub.5 -C.sub.10 alcohol, immersing the carrier without drying in an impregnating solution for a time sufficient to permit the impregnating solution to penetrate to a controlled depth without totally impregnating the carrier, and drying and calcining the impregnated carrier, whereby a contact material having an inner zone of substantially unimpregnated carrier and an outer zone of carrier impregnated with active material is produced. Sulfur dioxide is removed from flue gas by contacting the flue gas with a sorbent thus prepared. The preferred carrier for flue gas desulfurization is alumina and the preferred active material is copper oxide.
