Embodiment 1
[0030] At 16250μg / g FeSO 4 and 6250 μg / g NiSO 4 Add sodium dodecylbenzenesulfonate / Tween 80 addition amount to the foaming agent combination of 5g / L in the prepared composite catalyst aqueous solution, under the condition that the rotating speed is 5000r / min and the stirring temperature is 25°C, After stirring for 60 seconds, it is divided into upper and lower layers. The upper layer is a catalyst dispersion system in a stable foam state, and the lower layer is a clear liquid; the metal ion concentration of the foam layer (upper layer) and the clear liquid layer (lower layer) is carried out by atomic absorption spectroscopy during the half-life of the microfoam. Analysis, the results are shown in Table 1, and Table 2 is the main product yield of the suspended bed hydrogenation reaction after the catalyst is dispersed in Liaohe normal slag and Venezuelan normal slag in different ways.
