A method for continuously reacting particulate solids with gases and/or vapors at elevated pressures by feeding the particulate solids into a reaction zone under the pseudohydrostatic pressure generated by very tall fluidized columns of particulate solids, with the descent velocity of the solids and gas in the columns being greater than the ascent velocity of the gas. Fluidizing gas is preferably used at selected points in the column in order to avoid a harmful compaction of the particulate solids.
