.The tunnel kiln for carrier of RARE-EARTH multimetal oxides catalyst substitute white gold.

摘要

The object of the present invention is to replace noble metals such as platinum, heating method for firing, which is a highly technical process during remanufacturing of rare earth composite multimetal oxide terpolymer catalysts which simultaneously oxidize and reduce pollutants such as carbon monoxide, hydrocarbons, nitrogen oxides and sulfur compounds. The present invention provides a technique for manufacturing a firing furnace for firing a carrier and a carrier.;In order to achieve the above object, the present invention has a total length of 16-27m and 16 trillion-24 trillion, and a maximum operating temperature of 1500 degrees Celsius and a firing time of 15 hours to 20 hours is provided with an electric heating furnace.;According to the heating method for calcining the carrier of the platinum-rare rare earth composite multimetal oxide catalyst of the present invention and the calcining furnace therefor, the active ingredients are firmly adhered to the surface of the carrier by completely oxidizing the impurities mixed in the carrier and absorbing the impregnation solution. It is effective to prepare a carrier that is uniformly dispersed and bonded.
