Patents by Inventor Wolfgang Heschel

Wolfgang Heschel 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: 8133304
    Abstract: The invention concerns a process for the production of carbonaceous adsorption agents doped with elementary sulfur, in which sulfur is mixed with the adsorption agent, the mixture is heated to a temperature of between 120° C. and 150° C. and the temperature is maintained over a period of about an hour. The process is distinguished in that heating of the mixture is effected under a controlled oxygen-bearing atmosphere. The invention further concerns a process for waste gas cleaning using carbonaceous absorption agents doped with elementary sulfur. Preferably brown coal coke is used as the adsorption agent.
    Type: Grant

  • Patent number: 8008228
    Abstract: The invention concerns a carbonaceous sorbent in powder or grain form for the dry cleaning of waste gases from thermal processes. The sorbent includes carbon adsorbents from the group of activated carbon and/or brown coal cokes which are modified with sulfur and/or sulfur compounds. The sorbent is distinguished in that the specific surface area of the carbon adsorbents in m2/g in relation to the pore volume of the micropores in cm3/g is between 2400 and 2700.

  • Patent number: 7923397
    Abstract: Sorbent for the dry cleaning of waste gases charged with mercury and process for the production thereof. The sorbent includes as an adsorptively acting constituent for example activated carbons or activated cokes which are mixed with sulfur in powder form at ambient temperature, under the action of atmospheric oxygen. The sorbent is distinguished by a given ratio in respect of the median values of the grain size of the adsorptively operative constituent to the sulfur.
