In evaluating the activities of catalysts for hydrogenation of pyrolysis gasoline at low temperatures, a small autoclave of simple structure was used which could be operated easily and steadily. The relative deviation for parallel operations was less than 5%. By selecting styrene dissolved in an inert solvent as the model feedstock having a hydrogenation rate similar to that of pyrolysis gasoline and being simple and stable in composition, the disadvantages of using pyrolysis gasoline as the feedstock were eliminated...

In evaluating the activities of catalysts for hydrogenation of pyrolysis gasoline at low temperatures, a small autoclave of simple structure was used which could be operated easily and steadily. The relative deviation for parallel operations was less than 5%. By selecting styrene dissolved in an inert solvent as the model feedstock having a hydrogenation rate similar to that of pyrolysis gasoline and being simple and stable in composition, the disadvantages of using pyrolysis gasoline as the feedstock were eliminated and a good repeatability in the resutls was obtained. Although the results differ somewhat from those obtained by flowthermostatic method, the regularities of change agree quite well. Thus this evaluation method may be used as a supplement to the flow-thermostatic method.

该裂解汽油低温加氢催化剂的活性评价装置是间歇釜式,简单小巧,操作方便稳定,一人可完成全部操作,平行试验相对误差<5%。试验选用苯乙烯和惰性溶剂配制模拟原料,其评价结果重复性好,克服了以组成多变和稳定性差的裂解汽油为原料而造成的各种弊病。本法结果与流动等温实验装置结果虽有差异,但规律一致,因此,本方法可代替流动等温装置部分试验工作,是液相加氢催化剂研制中快速可靠的筛选方法。

The interferential factors that cause the change of radon data are discussed. The characters and regulars about the data of the outomatic observing radon in Panjin well I are analyzed.It is studied that the change of tide,air pressure and room temperature affect the observation data.To counter the seasonal variation in the observation radon,the isothermal equipment is installed in Panjin well I.
