静电纺Pd掺杂TiO2-ZrO2纳米纤维膜及其催化液化石油气红外燃烧性能研究
Study on electrospinning Pd-doping TiO2-ZrO2 nanofiber membranes and their catalytic performances in infrared combustion of liquefied petroleum gas
摘要
Abstract
The incomplete combustion phenomenon during direct combustion of liquefied petroleum gas can cause energy waste and pollution of environment,catalytic infrared combustion technology is usually used in the industrial field to improve the combustion process of liquefied petroleum gas.TiO2-ZrO2 nanofiber membranes with different Pd doping amounts(n(Pd)/n(total metal elements))were prepared by electrospinning method.The effects of Pd doping amounts on the structures of TiO2-ZrO2 nanofiber membranes were studied by SEM and XPS,and the effects of Pd doping amounts and calcination temperatures on the catalytic infrared combustion performances of liquefied petroleum gas of TiO2-ZrO2 nanofiber membranes were studied.The results show that Pd doping amount has significant effect on the TiO2 crystal forms and texture properties of TiO2-ZrO2 nanofiber membranes.When the Pd doping amount is too large(11%),the anatase TiO2 of the TiO2-ZrO2 nanofiber membrane can be converted to rutile TiO2,and the specific surface area and average pore size can decrease.Under the conditions of liquefied petroleum gas flow rate of 27 mL/min and air flow rate of 0.8 L/min,the TiO2-ZrO2 nanofiber membrane with Pd doping amount of 8%and calcination temperature of 600℃shows relatively best catalytic performance with the highest liquefied petroleum gas conversion rate of 99%and the highest combustion infrared temperature of 577℃.In addition,the nanofiber membrane has good stability and reusability.关键词
