Patents by Inventor Steve F. Janda

Steve F. Janda 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).

  • Patent number: 9700855
    Abstract: A mixer for a continuous flow reactor and methods for forming the mixer and the operation thereof. The mixer allows for segmentation of a primary reactant flow through a plurality of ports into many smaller flows that are injected as jets into a secondary reactant flow in channels of the mixer. The channel has a constant width dimension to enhance even flow distribution and local turbulence of the primary and secondary reactant flows. The constant width dimension of the channel and the size and number of the ports of the mixer can be configured to ensure the primary reactant flow injected into the channel directly impinges on a surface of the channel that is opposite the injection point at normal operating conditions.

  • Patent number: 8827544
    Abstract: A mixer (100) for a continuous flow reactor (330) and methods for forming the mixer and the operation thereof. The mixer allows for segmentation of a primary reactant flow through a plurality of ports (124) into many smaller flows that are injected as jets into a secondary reactant flow in channels of the mixer. The channel (126) has a constant width dimension to enhance even flow distribution and local, turbulence of the primary and secondary reactant flows. The constant width dimension of the channel and the size and number of the ports of the mixer can be configured to ensure the primary reactant flow injected into the channel directly impinges on a surface (116) of the channel that is opposite the injection point at normal operating conditions.

  • Patent number: 4248741
    Abstract: An improved process for preparing a silver catalyst which comprises impregnating a porous alumina support with a silver salt, preferably silver nitrate, by contacting a quantity of the support with an aqueous solution of the salt in sufficient amount to be completely absorbed by said support while under a vacuum. A dispersing agent is also employed in the aqueous silver salt solution. The support is dried by heating, e.g. 100.degree. C., under vacuum and then, while still under vacuum, impregnated with a reducing agent employing an amount sufficient to be completely absorbed by the support. Subsequent heating at a higher temperature, e.g. 250.degree. C., reduces the silver salt to silver metal. A catalyst is produced which, when employed for the oxidation of ethylene, permits the process to run 5.degree.-10.degree. C. cooler at the normal conversion and also gives an improved yield.
