Patent ID: 8883108

Claim:
A method for treating a hot gas consisting of exposing said hot gas to a composite material consisting of a metal oxide felt substrate and a catalytic material wherein said treating includes removal of sulfur compounds, and solid particulates, and metals from said hot gas wherein said metal oxide felt substrate comprises yttria stabilized ZrO 2 and the catalytic material comprises oxides of Mn, and said metal oxide felt substrate and catalytic material shows characteristic lines at 23.2±0.5 deg. 2-theta, 28.942±0.5 deg. 2-theta, 30.220±0.5 deg. 2-theta, 33.039±0.5 deg. 2-theta, 35.060±0.5 deg. 2-theta, 38.303±0.5 deg. 2-theta, 45.243±0.5 deg. 2-theta, 49.441±0.5 deg. 2-theta, 50.318±0.5 deg. 2-theta, 55.261±0.5 deg. 2-theta, 57.024±0.5 deg. 2-theta, 59.779±0.5 deg. 2-theta, 62.779±0.5 deg. 2-theta, 65.841±0.5 deg. 2-theta, under X-Ray Diffraction.
