NOVEL NANOPARTICULATE CATALYSTS FOR IMPROVED VOC TREATMENT DEVICES - PHASE I
Description:
Catalytic oxidation of VOCs is increasingly used for treatment of large-volume emissions at relatively dilute VOC levels. The best performing catalytic oxidation devices for attainment of very high VOC destruction levels employ precious metal catalysts, the costs of which are a very substantial element of the costs for operating these devices. The purpose of this Phase I SBIR project is to develop novel nanoparticulate supported precious-metal-based oxidation catalysts that will provide significantly increased catalyst utilization in VOC treatment devices. This will, in turn, translate into improved economics and VOC removal performance for such devices.
In the Phase I project, nanoparticulate platinum-on-alumina oxidation catalysts will be fabricated and incorporated within small honeycomb monolith channel flow "coupons." The coupons will be evaluated for oxidation of a model organic compound as a function of space velocity. Catalysts will be analyzed for relevant physical and chemical properties, and coupons will be analyzed for catalyst distribution. The primary objective of the project is to demonstrate that the coupons incorporating the novel catalysts have equivalent VOC destruction performance to coupons containing at least twice as much precious metal catalyst applied by conventional techniques.
