Fig. 1 is the method flow diagram of determination coal liquification device smoothness according to embodiments of the present invention, as shown in figure 1, should Method comprises the following steps：
Step S102, determine at least one index of coal liquification device.
In step s 102, above-mentioned coal liquification device is used to (contain material in the case of high pressure or high temperature and hydrogenation Have the solid particles such as coal and catalyst) handled, wherein, above-mentioned coal liquification device is specifically as follows Direct coal liquefaction device.
In a kind of optional embodiment, the device smoothness of Direct coal liquefaction device is calculated, the device smoothness is entered Row analysis obtains the running situation of the device.Wherein, the device smoothness for calculating Direct coal liquefaction device is straight by calculating coal Connect the smoothness of each index in liquefying plant and the index smoothness to each index is handled what is obtained.Above-mentioned coal is straight The index for connecing liquefying plant refers to that some can cause the parameter necessarily influenceed to the reaction of Direct coal liquefaction device.Specifically, Can determine by the following method a certain parameter whether be Direct coal liquefaction device index：The parameter is adjusted within the specific limits Numerical value, obtain run time of the Direct coal liquefaction device in the case where the numerical value of the parameter changes, finally judging should Whether run time is in predetermined scope, if in predetermined scope, it is determined that the parameter is Direct coal liquefaction device Index.
It should be noted that the selection of the index of above-mentioned Direct coal liquefaction device needs targeted, i.e. These parameters choosing Whether the smoothness for whether rationally determining Direct coal liquefaction device selected can truly reflect the running situation of the device.
In addition it is also necessary to explanation, above-mentioned coal liquification device includes multiple parameters (for example, feed pipe temperature, coal dust enter Doses etc.), but not all parameter can serve as the index of coal liquification device, wherein it is possible to as coal liquification device Index be that reaction on coal liquification device causes the parameter necessarily influenceed.
Produced by the above-mentioned steps S102 reactions that can be selected from the parameter of multiple coal liquification devices to coal liquification device The raw index necessarily influenceed, and then the smoothness of coal liquification device can be assessed according to the index of coal liquification device.
Step S104, data fitting is carried out to the parameter value of at least one index, the index for obtaining at least one index is put down Stability.
