Abstract
In this paper, on the basis of our low-swirl premixed stagnation flames, we develop a new high-swirl, rapidly-mixed tubular stagnation flame and demonstrate a synthesis process of nano-TiO2, aiming to solve for the limitation of low yields of current processes. By applying a central jet tube inside of the burner, the yield per MJ heat input of fuel by this new technique are 10 times higher than those produced by stagnation low-swirl flames, under similarly identical particle sizes and specific surface areas. Further, the doping synthesis of Pd-dispersed TiO2was carried out. The homogeneous Pd-TiO2catalyst can be obtained by flexibly controlling either the central jet inlet or the tangential inlet feeding, separately.
