Process for Producing Catalysts for Cleaning Industrial-Waste Gases.

摘要

The invention concerns catalysts that are effective for removal of nitrogen oxide (NO/sub x), carbon monoxide (CO) and hydrocarbons (HC) from automobile exhaust gases, waste gases from fixed combustion systems, and waste gases from chemical plants. The process for producing catalysts for cleaning industrial waste gases is characterized by the fact that a mixture of copper oxide and ferrosoferric oxide is calcined to such a state that a copper ferrite with spinel structure is formed by roasting.
