Abstract	Authors describe problems related to granular catalysts testing in hydrotreatment of petroleum distillates in laboratory. They explain requirements for laboratory facilities that ensure high reliability in determining the performance of diesel fraction hydrotreatment in industrial reactors. They demonstrate that diluting catalyst pellets with small particles of inert nonporous material (silicon carbide) makes it possible to obtain reproducible results in small three-phase reactors, minimizing such factors as the incomplete wetting of the catalyst, the wall effect, and the back-mixing of liquids.
