20210403342 · 2021-12-30 · ·

A method of manufacturing a catalytic sieve includes providing starting materials of an aggregate, a cementing agent, a sublimation agent and water. The sublimation agent (between 25% and 50% by weight of the cementing agent) is selected from molybdenum disulfide, tungsten disulfide, vanadium disulfide, copper sulfate, and combinations thereof. The aggregate contains at least 2% by weight of at least one transition metal. The method includes mixing the starting materials to achieve a mixture, placing the mixture into a form, and curing the mixture in the form to allow the mixture to become a solidified unit defined by a minimum dimension of thickness, length, width or diameter. The method further includes placing the solidified unit into a kiln, heating the kiln to 1115°−1350° C., maintaining the kiln at the temperature for between 10-60 minutes per centimeter of the minimum dimension, and removing the solidified unit from the kiln.
