Abstract

Process to supply solid particles to a fluidized bed via a substantially vertical riser which has an upper outlet opening in said fluidized bed and wherein the solid particles are transported upwards via the riser with a lift gas, which lift gas and solid particles are contacted at the lower end of the substantially vertical riser, wherein said contacting is performed by supplying the solid particles to the riser at a solids inlet point located at the lower end of the riser, part of the lift gas is supplied to the riser at a first inlet point located above the solids inlet point and part of the lift gas is supplied to the riser at a second inlet point at a position below the solids inlet point, such that in the riser a dense fluidized bed is present below the first lift gas inlet point and a more dilute fluidized bed is present above the first lift gas inlet point.
