The composition of modified monolith zeolite catalysts containing the basic components in the washcoating layer is suggested. When the washcoating layer contains 80 % zeolite, 10 % TiO2, and 10 % Al2O3, the catalyst exhibits both activity and adhesion strength. The titanium catalyst is stable to sulfur poisoning (H2S) at 500 °C; a small decrease in the catalyst activity at 400 °C is no longer observed after regeneration. Introducing 4 % mass Ce (calculated for respect to the washcoating) into the ready catalyst, one can preserve the catalyst activity and provide its stabile operation in the presence of water vapour both at 400 and 500 °C. Activity of the titanium-cerium-modified monolith catalyst is stable in the presence of water vapour and sulphur compounds in the gas mixture at a time.
