2. You are employed as an environmental engineer for a major chemical company that uses alcohols as liquid carriers for pigments to be used for decorating. Currently to meet local environmental regulations, the harmful emissions (1500 vppm) resulting from spraying and drying the coatings are thermally incinerated. However, this requires a thermal burner, which is expensive, consumes large amounts of fuel, and generates some NOx ( NO,NO2, and/or N2O). The plant manager, knowing you had a course in catalysis, is seeking an alternative to thermal incineration. You are asked to evaluate some fixed bed catalysts that will abate the alcohol emissions. You contact a catalyst company and they suggest you use a monolithic support with benefits of a lower low-pressure drop than a particulate bed of catalyst. They offer two catalysts: an inexpensive one with an activation energy (E) of 21.200cal/mol (21.2kcal/mol) and a second more expensive one with an activation energy of 12,000cal/mol(12kcal/mol). Compare the volumes needed for each assuming you want to achieve 90% conversion at 227C. Assume both catalysts have the same k0 (pre-exponential function). 3. Compare the volumes needed for two catalysts, one with E=48kJ/mol(12kcal/mol)
