The results of biomass air gasification in a fluidized-bed reactor are influenced by many factors,among which the reaction temperature and equivalence ratio have greater effects on the quality of producer gas.

In the present study, a down-draft gasifier is applied to treat municipal solid waste (MSW) in Guangzhou City through air gasification.

An experimental study on air gasification of polypropylene(PP) with 2 mm in particle diameter was carried out in a gasifier with 100 mm inner diameter and 3.

Effect of the variable contents of impurities and Ce addition on the toughening levels of alloys Al-Li-Cu-Zr and Al-Li-Mg-Zr with;

The method is to make steel work in safety term during toughening gradually.

But different treatments have different effects in toughening of high chromium cast iron.

Comparison about air-blown gasifier and oxygen-blown gasifier based on IGCC systems;

Study on air purification by plasma combined with photocatalysis;

Nanocatalytic techniques for air purification;

Application of TiO 2 in photocatalytic air purification and antibacterial materials;

Introduce ACF load nanometer TiO2 several main methods,and the sole factors which influence to TiO2/ACF adsorption photochemical catalysis purification air performance,such as the TiO2 surface hydroxyl content,the crystal compose,the thin film crystal grain size,thin film thickness,TiO2/ACF relative surface and so on,are analized.
