At the time, a flare was being used to oxidize the off-gases from various production processes and storage containers. Catalytic Products International developed a solution that utilized the capabilities of the VECTOR ...

  • Catalytic wet oxidation of ferulic acid

    Catalytic Wet Oxidation (CWO) of aqueous ferulic acid (a lignin model compound) was carried out under mild conditions (100?150?C, ~300 kPa PO2). Significant removal of ferulic acid (in terms of Total Organic Carbon (TOC)) (81% at 100?C and 95% at 150?C after 2 hr) was obtained using a CuNiCe/Al2O3 catalyst. A considerable portion of this TOC was removed during the heat-up period prior to oxygen ...

  • Achieving Air Pollution Control with Catalytic or Thermal Oxidizers

    As the full effect of 1990’s Federal Clean Air Act (CAA) Amendments continue to impact today’s industry, many manufacturing operations have become subject to stricter local, state and federal clean air regulations. Both VOC (volatile organic compound) and HAP (hazardous air pollutant) emissions are strictly regulated since they lead to the formation of ground-level ozone (or smog). The CAA ...

  • Catalytic wet hydrogen peroxide oxidation of a petrochemical wastewater

    Continuous Catalytic Wet Hydrogen Peroxide Oxidation (CWHPO) for the treatment of a petrochemical industry wastewater has been studied on a pilot plant scale process. The installation, based on a catalytic fixed bed reactor (FBR) coupled with a stirred tank reactor (STR), shows an interesting alternative for the intensification of a continuous CWHPO treatment. Agglomerated SBA-15 silica-supported ...

  • Case study - Catalytic oxidizer catalyst replacement

    Overview A New Jersey pharmaceutical company purchased a thermal incinerator to treat the heptane and hexane exhaust from their capsule wash system. The thermal incinerator"s "tubular" design was modified with a catalyst bed in order to reduce the system"s operational costs. Unfortunately, when operating in the catalytic mode, the oxidizer failed to provide the required ...

  • The catalytic oxidation of malachite green by the microwave-Fenton processes

    Catalytic oxidation of malachite green using the microwave-Fenton process was investigated. 0% of malachite green de-colorization using the microwave process and 23.5% of malachite green de-colorization using the Fenton process were observed within 5 minutes. In contrast 95.4% of malachite green de-colorization using the microwave-Fenton was observed in 5 minutes. During the microwave-Fenton ...

  • Case study - Engine cell exhaust: Catalytic oxidizer

    Overview Endurance testing of outboard motors for boats has typically been done in lakes and sometimes on barges. This testing was time consuming, presented logistic problems and removed the testing from the R & D department and the factory. When a company in Oklahoma decided to build their own endurance test cell area, the Environmental Protection Agency required them to control the ...

  • Case study - Styrene emissions: Catalytic oxidizer with concentrator

    Overview The world's largest button manufacturer needed a pollution control system that would destroy styrene emissions from a variety of plant processes. The plant was proactively seeking a cost-effective air pollution control solution to preempt future regulatory action. The main concern of the customer was the high operating cost of an emission control system. ...

  • Selective catalytic reduction of nitric oxide over copper oxide and cerium oxide catalysts
