First Claim
Patent Images
1. A method of producing a pollutant adsorption, and degradation article, including the steps of:
- forming a mixture of dry solids of at least one adsorbent including a zeolite absorbent and at least one pollutant transforming agent comprising iron;
compacting said mixture to form a porous, permeable article; and
, modifying said article with surfactant after said compacting step or adding said surfactant to said mixture prior to said compacting step, wherein the substituents of said mixture are not dissolved but maintain their chemical composition.

Abstract
A method of producing a pollutant adsorption and degradation article, and such article, are provided. At least one adsorbent is mixed with at least one pollutant transforming agent to form a mixture. This mixture is compacted to form a porous, highly permeable article. If necessary, the article can be modified with surfactant either after the compacting step or by adding the surfactant to the mixture prior to the compacting step. In addition, if necessary, a binding agent can be added to the mixture prior to the compacting step.
