The numerical simulation for the gas-solid two phase in the front and back of test-section of sand and dust environmental test is discussed.

Based on the theory of gas-liquid airlift loop reactor, a novel two-stage gas-solid airlift loop reactor (ALR) was designed.

The gas-solid flow behavior in spouted bed was simulated using the two-fluid model.

Experiments of pulverized coal dense-phase pneumatic conveying using nitrogen were carried out in an experimental setup at the pressure up to 4 MPa and the solid-gas ratio up to 500 kg/m3.

On a high-pressure pneumatic conveyance test stand with a conveyance pressure and solid-gas ratio being respectively as high as 4.

Experiments of dense-phase pneumatic conveying of pulverized coal using nitrogen were carried out in an experimental test facility with the conveying pressure up to 4MPa and the solid-gas ratio up to 450kg/m3.

Then it was converted to carbamoyl chloride by treating it with bis(trichloromethyl)carbonate in toluene.

It was produced by the chemical reaction of γ-butyrolactone as an orginal material, reacted with bis(trichloromethyl)carbonate and isopropanol et al.

It was produced by the chemical reaction of 2,4,6-trichloro- phenol as an orginal material,reacted with 1,2-dichloroethane, propylamine, bis(trichloromethyl)carbonate and imidazole one by one.
