Catalyst carrier of conducting type honeycomb ceramics and its preparation method

Abstract

An electrically conductive honeycomb ceramics as the carreir of catalyst for car is prepared from purified titanium oxide powder, or Ti powder or iron oxide powder, B2O3 or graphite powder, and pure aluminium powder through mixing, adding organic adhesive, die pressing, heat treating and high-temp synthesis by self combustion.

Description

technical field [0001] The invention relates to a catalyst carrier for a vehicle, more specifically, the invention relates to a ceramic carrier material used in a catalytic converter for exhaust gas of an automobile. At the same time, the present invention also relates to a preparation method of the catalyst carrier. Background technique [0002] The development of modern society has led to a substantial increase in the number of automobiles, and the pollution generated by exhaust emissions has also increased significantly. Developed areas where cars are concentrated, especially big cities. Pollution from tail gas emissions has accounted for 50% to 60% of air pollution in these areas. With people's emphasis on the living environment, reducing vehicle exhaust emissions and controlling exhaust pollution has become a topic of concern both at home and abroad. Technically speaking, there are three methods to reduce vehicle exhaust emissions: pre-measu...

AI Technical Summary

Problems solved by technology

However, it also has many disadvantages, such as large heat capacity, and it takes a long time to start, at least 3 to 10 minutes, to make the catalyst work effectively

However, studies have shown that 3 to 10 minutes after start-up is the time when car pollution is the most serious. The delayed activation of the catalyst prevents the exhaust gas from being cleaned in time after start-up, and the problem of environmental pollution has not been completely resolved.
