Sample holder for determining content of catalyst in oil slurry by using ash content method and test method

The invention relates to a sample holder for determining the content of a catalyst in oil slurry by using an ash content method and a test method, which can realize rapid detection of the content of the catalyst in the oil slurry. The sample rack, a crucible, a drying oven, a muffle furnace and an electronic balance are mainly adopted for testing according to the steps of heating, preheating, carbonization, combustion, weighing and the like. The sample holder comprises an upper layer and a lower layer, wherein the upper layer is a hollow circular truncated cone body, the lower layer is a hollow cone body, the hollow circular truncated cone body comprises a circular truncated cone body lower section, a perforated annular groove, a hollow circular truncated cone body upper section, a groove outer edge and an annular groove hole, the hollow cone body comprises a cone body bottom surface, the hollow circular truncated cone body is located above the hollow cone body, the hollow circular truncated cone body and hol
