A recently granted patent (Publication Number: US11813591B2) discloses an ethylene degradation catalyst that includes TiO2 crystals with auxiliary agents. The catalyst features a specific crystalline form of TiO2 crystal, an anatase type, with a TiO2 disordered layer containing surface hydroxyl groups. Additionally, the catalyst contains precise amounts of K2O and Na2O, ranging from 0.002-0.006 wt % and 0.006-0.098 wt %, respectively, based on the total weight of the catalyst. The TiO2 disordered layer's molar percentage of Ti3+ in Ti elements falls within a range of 2.15%-10.37%, contributing to its unique composition.
Furthermore, the patent outlines a method for preparing the ethylene degradation catalyst, involving several steps such as mixing a titanium source powder with an acid, water leaching, hydrolysis, and aging to obtain a metatitanic acid colloid. The process includes specific conditions like roasting temperature, time, and particle size of the titanium source powder. The method also details hydrogenation conditions for preparing the catalyst, including temperature, time, hydrogen concentration, and flow rate. The patent emphasizes the use of spent SCR denitration catalysts containing Na2O and K2O as the titanium source powder, highlighting the innovative approach to catalyst development for ethylene degradation.
