Currently, spent V2O5-WO3/TiO2 catalyst contributes significant amount of solid wastes following the increasing global demands. V2O5-WO3/TiO2 catalysts have usually consisted of TiO2 anatase as a supporting oxide, vanadium as a catalytic agent and other promoters such as W, Si, Ca. Although V is the main catalytic agent, relatively high content (WO3, 7 – 10 wt.%) of W is usually composed comparing to V (0.5 – 1.5 wt.%). Considering the irreplaceable properties and industrial importance of tungsten, recycling of spent SCR catalyst should be established to utilize as an another secondary source. This paper deals with the process to recover tungsten from spent V2O5-WO3/TiO2 catalyst. Proposed processes in this study are the in order of roasting, decomposition using HCl, ammonia leaching, and crystallization. According to processes in this study, ammonium paratungstate (71 wt%) was obtained as a final product. Total yield rate of W from feedstock was revealed to be 96.3%.
