Study on the purification Efficience of Automotive Exhaust Gas and the Structure Character of CuO-Al_2O_3 Catalyst

摘要

A 10000km driving test was given to one test car equipped with CuO-Al_20_3 Catalyst for oxidation of CO and HC. The property changes and the structure character of the catalyst between before and after the use were examied by X-ray diffraction, BET and hardness meter and so on. The deterioration of the catalytic activity seemed to depend on the decrease of the specific surface area and the crystal structure change.
