A catalyst which efficiently removes particulate matter, SOF, sulfate, and SOOT and the like from the exhaust gas from such an internal combustion engine as a diesel engine without inducing a rise in the back pressure of the engine is provided. The catalyst for the purification of the exhaust gas of an internal combustion engine is formed by using an open flow honeycomb containing in the channel walls thereof such pores as possess an average diameter in the range of 10-40 &#x3bc;m.

Catalyst for purifying exhaust emission from internal combustion engine, method for preparation thereof and method for purifying exhaust emission from internal combustion engine

An exhaust gas purifying catalyst contains copper oxide, ZSM-5 and/or zeolite &#x3b2;, and an oxide of magnesium and/or calcium is further added thereto. A process for purifying an exhaust gas using such a catalyst is also included. By using the catalyst, NOx in an exhaust gas containing much oxygen such as exhaust gas of diesel engines can be efficiently removed and oxidation of SOunder high-temperature conditions can be suppressed.

Exhaust gas purifying catalyst and process for purifying exhaust gas

An exhaust gas purifying catalyst has a catalytic component including copper, ZSM-5, and &#x3b2; zeolite. This exhaust gas purifying catalyst reduces nitrogen oxides even from low temperature range and exhibits durability even under a thermal load of high temperature.
