Catalyst for VOC treatment

Abstract

The invention aims to provide a catalyst that enables a simultaneous treatment of a VOC containing an aromatic group and a VOC containing no aromatic group in a temperature range lower than 300 DEG C.A catalyst for a VOC treatment, in which platinum is directly carried on a cobalt-cerium system complex oxide, is intended to be used in a combustion treatment of a VOC-containing gas. The mass ratioof the cobalt-cerium system complex oxide is 80% or more based on the total mass of the catalyst. When a (unit: mass%) is a content of the platinum based on the mass of the cobalt-cerium complex oxide, a satisfies 0<a<=20. The catalyst may be or may not be carried on an inert carrier.

Description

technical field [0001] The present invention relates to a platinum-supported cobalt-cerium composite oxide catalyst directly used for treating volatile organic compounds (VOC). Background technique [0002] Technology is being sought to easily deal with volatile organic compounds (Volatile Organic Compounds: hereinafter referred to as "VOC") that may cause odor complaints caused by exhaust gases from painting factories, printing factories, chemical factories, etc. , The causes of air pollution problems, and the causes of health damage caused by release from building materials used in homes and offices. As treatment methods, various methods such as direct combustion method, catalytic combustion method, physicochemical adsorption method, biological treatment method, and plasma method have been proposed. Among them, the catalytic combustion method is easier to install and maintain, so it is being especially used widely used. [0003] However, the treatment by the catalytic co...

Problems solved by technology

[0003] However, the treatment by the catalytic combustion method usually requires a temperature of about 300 to 350°C, so there is a problem that electricity costs and fuel costs are consumed due to heating.

In addition, when this method is applied to home and office equipment, the electricity bill is also high, and there are problems in ensuring safety and miniaturization, and the scope of application is limited.
