Carbon composites for the reduction of nitrogen oxides, process for their preparation and applications.

摘要

COMPOSITE OF CARBON REDUCTION OF NITROGEN OXIDES, PREPARATION PROCESS AND APPLICATIONS. The composite INCLUDES: 60-80% BY WEIGHT OF COAL, 10-20% by weight of a 2-5% HUMIC ACID AND WEIGHT OF A CATALYST OF POTASSIUM. The method comprises admixing THE THREE COMPONENTS in the amounts indicated, followed by drying and pressing the mixture to obtain pieces of the desired shape, which are dried at 110C ONES AND pyrolyze under N2 between 400 and 700C. Composites have application in reducing nitrogen oxides PRODUCED IN INDUSTRIAL COMBUSTION PROCESSES OR COMBUSTION PROCESSES OF AUTOMOBILES.
