ABSTRACT A process for fluidized contact which comprises contacting a liquid or a mixture of a liquid and a gas intimately with solid particles. More specifically, the process comprises introducing a porous packing into at least a part of a contact zone to form a porous packed bed, then introducing solid particles into the lower part of the contact zone, feeding a liquid or a mixture of a liquid and a gas (to be referred to as a "fluid") from the lower part of the contact zone to form a fluidized bed of the solid particles, where- by the fluid is contacted intimately with the solid particles within the contact zone and the fluidized porous packed bed. In the process, the ratio of the superficial volume occupied by the porous packed bed to the real volume of the porous packing is adjusted to at least 1.3, and the ratio of the average pors diameter of the pores of the porous packing to the average particle diameter of the solid particles is adjusted to 1.1 to 10Ø The process is suitable for use, for example, in physical treatment processes such as absorption and drying, and in chemical treatment processes such as alkylation of hydrocarbons
