Introduction

In the 1980s, Cataler launched a line of main products one after another. We started production of coal-derived activated carbon for canisters and monolith 3-way catalysts. The world's first high-tech 3-way catalyst was called the “Camry catalyst”, and was highly acclaimed by the EPA (US Environmental Protection Agency).

World's first high-tech 3-way catalyst
"Camry catalyst" development

When the 3-way monolith catalyst became the mainstream, Cataler was the first in the world to develop the "High Ceria Catalyst". By utilizing the oxygen storage capacity of ceria, the air-fuel ratio range in which the catalyst works could expand and the exhaust gas purification performance was improved. As an oxygen storage (O₂ Storage) type catalyst, it became the mainstream of subsequent 3-way catalysts.
This catalyst was called the "Camry catalyst" in analogy to Toyota's representative model "Camry", and its performance was highly acclaimed by the EPA (US Environmental Protection Agency).
