The role of ceramic materials and technologies for environmental protection is already highly visible and will increase in future (e.g. porous materials).
  • Automotive industry will likely remain a principal driving force for development of ceramics with high environmental impact(high porosity, ash resistant compositions, four way catalytic filtrations systems, high filtration effeciency, more efficient and robust catalysts, higher sensitivity ceramic sensors).
  • This will create technology that can be leveraged to other areas (filtration, separation) and other applications in chemical, petrochemical and power generation industries.
  • Other key areas: harvesting and use of clean energy, clean water and green construction materials

Ceramic materials have important roles in controlling emissions from vehicles

Gasoline Monolithic catalysts substrateOxygen Sensors

TWC Catalyst thermal stability

Diesel Monolithic catalysts substrates Catalyst thermal stability

Ceramic wall flow filters

The Future Integration of more catalyst functionality into single ceramic filter units

Huge demands on catalytic chemistry and ceramic science

“Roles of Ceramicsin Controlling Car Exhaust Emissions”

slide13
Extruded synthetic Cordierite with low CTE has been successfully used as macro-cellular body for exhaust catalyst support during the last 30 years
  • Ceramic filters have successfully been applied to Diesel Particulate Filters with active regeneration for 20 years and extensively during the last 10 years
    • Challenges to use oxide ceramics for this particular demanding application have been overcome
  • The use of oxide cellular ceramics honeycombs as high surface area extruded catalyst remains an active area of research with many promising applications for remediation of both mobile and stationary emissions as well as for use in the chemical processing industry

A re-crystallized porous SiC material was obtained by mixing a coarse powder and a fine powder of SiC at a fixed rate and firing the mixture at a high temperature of 2000ºC or more. The material obtained has a uniform pore diameter distribution compared with other materials, and is suitable as a DPF material.

Progress in theDevelopmentofthe Diesel Vehicle Business”

slide15

Functional ceramics enable significantly reduced vehicle emissions (fuelinjection system - piezoelectric multilayer actuators, exhaust gas sensor - ceramic sensor element, park pilot - piezoelectrictransducer, diesel particulate filter - ceramic filter substrate)

To take advantage of the full potential for reduction ofemissions,a thorough understanding of material properties and sophisticated modeling approaches are necessary.

chall e nges
Challenges
  • Industrial attention is limited to certain applications. There are many other applications to be innovated (e.g. chemical, petrochemical and power generation industries) including on the current usage (e.g. particulate filter for gasoline engines) – be proactive rather than reactive.
  • System design rather than parts. Therefore, Interdisiplinary and transdisciplinary research is needed – ”open innovation”
  • Education and public awareness should be improved
  • Cost
enablers
Enablers
  • Regulations (more link with policy makers)
  • Chemistry (catalysts, substrate materials)
  • Processing and manufacturing technologies
  • Design (system, crystal chemistry, microstructure)
  • Material (alternative materials)
  • Modelling
