Abstract:
A urea reagent exhaust treatment fluid configured for use in treating an exhaust produced by an internal combustion engine comprising water, an amount of urea that is about 32.5 wt %, and an amount of biuret that is at most 0.09 wt %, and a method for manufacturing an aqueous urea reagent exhaust treatment fluid that includes feeding an aqueous urea exhaust treatment fluid including biuret to a filter including a filter element including an adsorbent material having a biuret conversion catalyst. The aqueous urea exhaust treatment fluid is filtered using the filter element by adsorbing the biuret from the aqueous urea exhaust treatment fluid with the adsorbent material, and converting the biuret into a material useful for exhaust after-treatment or into a material that is innocuous, wherein an amount of the biuret remaining in the aqueous urea exhaust treatment fluid after the filtering is at most 0.09 wt %.

Claim (Index 18):
The method according to  claim 15 , wherein the biuret conversion catalyst is a material selected from the group consisting of alkali or alkaline earth metal oxides, hydroxides, and carbonates.
