Popis:	Effective diffusivities of polyaromatic solutes in aliphatic solvents were determined from adsorption measurements at ambient conditions with three hydrotreating catalysts of pore diameters 6.2-17.5 nm. Solutes studied were dislike (coronene, 9-phenylcarbazole, tetraphenylporphyrin, and tetra(4-biphenylyl) and rodlike (naphthalene, anthracene, benzanthracene, and dibenz- anthracene) polyaromatics of critical dimensions ranging from 0.74 to 2.18 nm. A modified Wilke-Chang-type correlation was developed to predict bulk diffusivities of the polyaromatic solutes in aliphatic solvents
