| description | The invention discloses a catalyst for selective oxidation of non-methane total hydrocarbons. Raw materials comprise ZrO2, SnO2, Nb2O5, platinum nitrate, ammonium molybdate and vanadyl oxalate. The invention also provides a method for preparing the catalyst. The method comprises the steps: (1) preparing ZrO2-SnO2 composite oxide; (2) preparation of an Nb2O5-ZrO2-SnO2 carrier; and (3) preparation of the Pt-Mo-V/Nb2O5-ZrO2-SnO2 catalyst. The catalyst provided by the invention has the advantages that the noble metal Pt content of the catalyst is low, the catalytic activity is high, at the reaction temperature of 300 DEG C, the conversion rate of oxidation of ethane, propane, methylbenzene, benzene, ethyl acetate, acetone and ethanol can be 99.5% or above, and the conversion rate of oxidationof methane is less than 5%.
本发明公开的一种非甲烷总烃选择性氧化催化剂，原材料包括ZrO、SnO、NbO、硝酸铂、钼酸铵、草酸氧钒。本发明还提供了制备所述催化剂的方法：(1)ZrO-SnO复合氧化物的制备；(2)NbO-ZrO-SnO载体的制备；(3)Pt-Mo-V/NbO-ZrO-SnO催化剂的制备。其优点在于，本发明提供的这种催化剂贵金属Pt含量低、催化活性高，在300℃的反应温度下，即可对乙烷、丙烷、甲苯、苯、乙 |
