Abstract
Abstract Nitrogen trichloride produced in situ from the reaction of a chlorine source and a nitrogen source in a non-aqueous fluid is adsorbed on an adsorption media and serves to oxidize, bleach or deactivate contaminants and foreign matter of the fluid similarly adsorbed on said adsorption media.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
54 words
A method for oxidizing or bleaching a contaminant in a non-aqueous fluid which comprises forming nitrogen trichloride in situ by the reaction of a chlorine source and a nitrogen source in said fluid, and adsorbing said contaminant and said nitrogen trichloride on a solid adsorbent, and recovering said fluid substantially free of acid contaminant.
Claim 2
Independent Claim
54 words
A method for oxidizing or bleaching a contaminant in a non-aqueous fluid which comprises forming nitrogen trichloride in situ by the reaction of a chlorine source and a nitrogen source in said fluid, and adsorbing said contaminant and said nitrogen trichloride on a solid adsorbent, and recovering said fluid substantially free of acid contaminant.
Claim 3
Dependent Claim
22 words
The method of claim 1 wherein said chlorine source is selected from the group consisting of trichloroisocyanuric acid and alkaline earth hypochlorites.
Claim 4
Dependent Claim
19 words
The method of claim 1 wherein said nitrogen source is selected from the group consisting of amines and urea.
Claim 5
Dependent Claim
23 words
The method of claim 1 wherein said nitrogen trichloride concentration in the fluid is less than 10% but sufficient for oxidizing said contaminant.
Claim 6
Dependent Claim
21 words
The method of claim 1 wherein said adsorbent is selected from the group consisting of carbon, Fuller's earth and activated bauxite.
Claim 7
Dependent Claim
20 words
The process of claim 1 wherein said non-aqueous fluid is selected from the group consisting of hydrocarbons and halogenated hydrocarbons.
