　WFS-3015, is a online reaction equipment for quick catalysts evaluation with a simple structure and humanized design. Several flows including one liquid and two gas lines pass through the mixer and vaporizer in sequence, and then enter into the reactor. The reactor with a special configuration includes a quartz tube and an opening furnace which can be applied at high pressure. The outlet gas is sampled into the chromatograph under the help of the six-valve after bypass split and pressure release but without temperature decrease. In addition, the instrument consists of refrigeration system, individual cooler and gas-liquid separator. For the advantages above, it is proved to be perfect equipment for online catalysts evaluation in scientific research.Main technical index:1、Sample volume: 0~1 ml,2、Reaction pressure: 0~3 MPa for quartz reactor and 0~10 MPa for stainless steel reactor,3、Reaction temperature: r.t. ~400 oC for quartz reactor and r.t. ~600 oC for stainless steel reactor,4、Gas flow rate: 0~300 ml/min,5、Vaporizer temperature: r.t.~200 oC,6、Gas-liquid separator temperature: -30 oC~r.t.,7、Liquid injection pump: 0.001~9.999 ml/min,8、Injection valve temperature: 320 oC,9、Temperature control precision: ±0.2% FS,10、Temperature program of seven stages with individual PID control,11、Gas flow rate of 0~300 ml/min controlled by mass flowmeter with the precision of ±2%.
