Same emissions reduction performance as precious metal-based catalysts.
Johnson Matthey has developed a new low cost, base-metal HalocatTM SC29 Catalyst specifically designed to reduce up to 99 percent of VOC and toxic organic compounds from PTA (purified terephthalic acid) manufacturing plants.
Available from Johnson Matthey’s Stationary Emissions Control (SEC) group, the breakthrough HalocatTM SC29 catalyst has these important advantages:
- Significant lower cost of ownership with the same leading VOC reduction.
- Smaller capital investment because SC29 catalyst does not contain high cost platinum group metals (PGM) such as platinum, rhodium or palladium.
- Price protection against market fluctuations in precious metal.
- High VOC reduction performance that is equivalent to more expensive precious metal catalysts.
“Johnson Matthey’s SC29 catalyst is a technological breakthrough for the PTA industry. Plants can now install lower cost SC29 catalyst in their new plants or replace their existing PGM catalysts with non-PGM catalysts; the savings from reclaiming the precious metal will nearly offset the cost of the SC29 catalyst,” said Jeff Sherman, Johnson Matthey SEC LLC President.
Halocat SC29 catalyst targets pollutants in PTA plant exhaust streams, including carbon monoxide, methyl bromide, acetic acid, benzene, toluene, alcohols, acetates, formates and xylenes.
“Johnson Matthey SEC is the worldwide leader in catalyst technology to reduce emissions from PTA and other industrial processes, continuously innovating to develop catalysts to help our customers comply with strict environmental regulations,” said Sherman.
“SEC offers a complete range of oxidation catalyst formulations supported on metallic or ceramic substrate for specific applications. These catalysts have reduced tons of VOC and halogenated VOC emissions from manufacturing plants since the 1960s.”
Johnson Matthey’s first PTA emissions catalyst was Halocat AH 400. It was widely used at PTA plants operating in the U.S., Asia, Europe and South America. Today, Johnson Matthey’s custom fabricated Halocat catalysts are installed at more than half of the PTA plants throughout the world, including those using Compress, Invista, BP and GTC Technology processes.
