[0083] Catalyst Performance Evaluation Test

[0084] Catalyst methane oxidation activity measurements were carried out in a fully automatic parallel, high-throughput catalyst test rig with 48 fixed-bed reactors made of stainless steel (each with a total volume of 1 mL). The catalysts were tested using simulated exhaust gas compositions and operating conditions similar to those of a natural gas fueled engine operating in excess of oxygen (fuel lean). The conditions used for the test are shown in Table 1.

[0085] Table 1

[0086]

[0087] The sieved catalyst fraction with a particle size of 315-500 μm was used for catalytic performance testing. For reactor loading, the required mass of catalyst was diluted to 1 mL of total reactor volume with inert material (corundum) of the same particle size...

Abstract

The invention provides a process for preparing a methane oxidation catalyst comprising a mechanochemical treatment, a methane oxidation catalyst thus prepared and a method of oxidizing methane.

Description

technical field [0001] The present invention relates to a methane oxidation catalyst, a method for preparing the methane oxidation catalyst, a methane oxidation catalyst prepared by the method and a method for using the methane oxidation catalyst. Background technique [0002] One of the most abundant and economically viable alternatives to petroleum-derived fuels such as gasoline, kerosene and diesel is natural gas. As a result, engine manufacturers targeting transportation and stationary applications are turning their attention from traditional petroleum-derived fuels to cheaper, cleaner-burning and more environmentally friendly compressed natural gas (CNG) or liquefied natural gas (LNG) , LNG) fuel. In recent years, considerable investment and effort has been made to expand the natural gas fuel supply chain / infrastructure and develop natural gas-specific engine hardware to enable widespread adoption of natural gas as a fuel. The main component of natural gas is methane....
