Methane reforming with CO2 in the presence of oxygen was studied in a fluidized bed reactor.

The W Fe MgO catalyst was prepared by calcination of the mixture of Mg(NO 3) 2·6H 2O, Fe(NO 3) 3·9H 2O, ammonium tungstate and citric acid at 823 K and used to prepare single walled carbon nanotubes (SWCNTs) in a fluidized bed reactor with 25%CH 4 H 2 or 25%CH 4 Ar gas mixture at 1?073 ～ 1?373 K.

Some equations were given to confirm parameters of fluidized-bed reactor,such as gas velocity,reactor size,and production capability and so on.

Results of the experiments on HCI removal with these absorbents in fluidized-bed reactor show that: (1) HCI retention capability of these modified absorbents increase with temperature when the temperature lower than 760癈; (2) with modified Ca(OH)2 as absorbents in fluidized-bed reactor, the HCI ret.

The present situation of cyclone separators used in acrylonitrile fluidized-bed reactors is briefly analysed.

Based on the model of gas-solid heat transfer in concurrent down-flow circulating fluid bed reactor, particle temperature distribution in axial direction and the inlet and outlet temperature of the gas-solid phase in concurrent down-flow circulating fluid bed reactor at different operation conditions were measured with stable heat transfer method.

This paper introduces the orthogonal optimization experiment design of operating factors and the actual experiment results on a fluid bed reactor of acrylonitrile apparatus.

After analyzing the produce technics of import system of acrylonitrile fluid bed reactor,the paper applied PID parameter auto-tuning software based on the method of correlation coefficient to regulate the general PID controller s parameter of the system,and acquired well control effect.
