The test results indicate that the use of oxygen-enriched intake air considerably improved the starting performance of the DI diesel engine.

So the nitrogen enriched intake air combustion becomes a effective method to take the place of exhaust gas recirculation.

Design program on production of 300000 t/a methanol by rich oxygen gasification with anthracite coal and co-production of 150000 t/a ammonia with tail gas;

This paper takes one Chengdu float glass production line for example,discusses oxygen-rich air collection method of nitrogen station in float glass plant and its effect factors in collecting oxygen-rich air,and also puts forward some suggestions about nitrogen station oxygen-rich air system s design.

Microwave reactor with urea and Ga-A zeolites was set up to study removal of NO_x with excess oxygen from waste gas.
