The oil fume is threat to human health. Currently, the equipment to eliminate oil fume is not very efficient, especially in odor removal. Most of high-efficient equipment for oil fume elimination is too expensive to be available for many small restaurants. Therefore, we need high-efficient equipment with reasonable cost to remove oil fume for restaurants. Currently the electrostatic precipitator has been used to remove oil-fume in most of restaurant kitchens. The oil particles are positive or negative charged in a high-voltage field so they can be collected on the electrostatic plates. The collection of oil particles is very high up to 85-90%. However, for odor molecules, the removal efficiency can only achieve 40-60%. This industrial-academic proposal aims for the development of a low-temperature catalytic incineration to further destroy the odor molecules after the electrostatic precipitator. So the odor of kitchen fume can be completely eliminated. Our previous result indicated that hydrophobic noble-metal catalyst could completely oxidized VOCs at low temperature so that less fuel was required to sustain the working temperature. In addition, the activity of the catalyst could be enhanced because the moisture of the kitchen fume has little effect on the hydrophobic surface. Thus the odor of oil-fume can be completely reduced. The research will collaborate with Professor Chiang Wei-Hung of National Taiwan University of Science and Technology to develop hydrophobic carbon material, which will be used for the support of active low-temperature combustion catalysts. We will prepare hydrophobic noble-metal catalyst using carbon nano tube, characterize catalysts, assemble the reaction system, perform the catalytic incineration of oil fume, analyze the component of oil fume and improve the efficiency of oil-fume removal. In addition, we will establish the catalytic honeycomb system using high-active hydrophobic catalysts. Such hydrophobic catalyst will be loaded on a honeycomb catalytic reactor, which allows low pressure-loss in the duct of the kitchen hood. We expect >90% odor removal of oil fume under the facial velocity 1.2-1.4 m/s and pressure loss < 10 cm H2O in the duct. The research outcome will be cooperated with a commercial company to develop a total system for restaurants. A feasible analysis will also be carried out.廚房油煙臭味觸媒焚燒疏水性觸媒蜂巢式反應器kitchen fumestink odorcatalytic incinerationhydrophobic catalysthoneycomb reactor
