In order to lessen the effects of industrial gas exhaust systems, Murata has announced the development of a novel ceramic catalyst material.
This ceramic catalyst material is used in the production of ceramic catalysts by Shanghai FT Technology Co., Ltd., a Chinese manufacturer (F-Tech).
This ceramic solution contains no precious metals, unlike conventional exhaust treatment system catalysts, and it dramatically lowers CO2 emissions as well as the amount of natural gas needed in the treatment process.
Exhaust gasses from a variety of industrial production processes need to be treated in order to keep dangerous particulates out of the atmosphere.
Regenerative thermal oxidizers (RTOs) are used in various applications to burn exhaust gas with natural gas in order to breakdown and treat it. This removes odorous emissions, volatile organic compounds (VOCs), and hazardous air pollutants (HAPs) that are produced during industrial processes.
Reducing fuel usage and carbon footprints is a top priority for industrial production facilities due to the rising cost of natural gas and the pressing need to prioritize global sustainability.
Constructed with Murata’s vast expertise in ceramic capacitors, the ceramic catalyst material has remarkable heat resistance and has the capability to handle extremely concentrated exhaust gas.
In terms of performance, ceramic catalyst material set temperature can be lowered from about 850°C to 700°C by adding Murata’s ceramic catalyst into an exhaust gas treatment system that is already in place.
Figure 1 shows that by decreasing the set temperature system, heat loss is minimized and the self-combustion rate is accelerated, resulting in a 53% reduction in natural gas consumption.
This modification in operating circumstances also leads to a reduction in CO2 emissions from natural gas consumption, which lessens the environmental effect and also greatly lowers operating expenses.
Numerous benefits are also provided by the ceramic substance. First and foremost, there are no price swings like there are with precious metals, making the initial system cost far more predictable.
Moreover, ceramic catalyst material at high temperatures have the potential to degrade the effectiveness of precious metal catalysts because the active element may migrate and form bigger clusters.
The ceramic catalyst material efficiency degrades as a result of this process, known as sintering, which decreases the quantity and size of active sites.
As opposed to precious metal catalysts, ceramic catalyst materials have active components distributed throughout their crystal structure and do not deteriorate even while operating at high temperatures. This results in an extended lifespan.
The ceramic catalyst has significantly reduced operating costs and the environmental effect of RTO systems in practical applications at Murata’s production and partner sites. The installation at Wuxi Murata Electronics Co. achieved complete system payback in just 13 months.
“With Murata’s patented ceramic catalyst material, we have taken our extensive ceramic capacitor knowledge and applied it to another market to create a truly innovative solution,” said Koichi Kawakita, Vice President Manufacturing Group Ceramic Capacitor Business Unit. He continued, “In terms of operation, it can help factory designers and exhaust gas treatment manufacturers achieve significant reductions in natural gas consumption and carbon emissions, while also cutting dependence on precious metals.”
