摘要： A process for separating propylene mixed with propane by adsorption in a simulated moving bed is described. The process operates in the gaseous phase or in the liquid phase, and it uses a 13X faujasite-type zeolite as adsorbent solid and butene-1 or isobutane or any mixture of these 2 components as desorbent.

摘要： A process for separating a feed F by simulated moving bed adsorption in a SMB device comprises at least one zone 1 for desorption of the compounds produced in the extract, a zone 2 for desorption of the compounds produced in the raffinate, a zone 3 for adsorption of the compounds produced in the extract, a zone 4 located between the raffinate withdrawal and the desorbant supply, the device comprising external by-pass lines Li/i+1 directly connecting two successive plates Pi and Pi+1;in which the degree of opening of means for restricting the flushing flow rate of the by-pass lines Li/i+1 are sequentially modified such that: 1) in an operational zone where there is at least one closed by-pass line, a super-synchronicity of the flushing flow rate is established in all of the by-pass lines which are not closed belonging to the zone under consideration, said super-synchronicity being defined by the following formula: S=a+b(nf/nt) in which the constant a is a constant in the range −5 to 5 and b is a constant in the range 40 to 100; 2) if there is no closed by-pass line in the zone under consideration (in other words if all of the by-pass lines of the zone are open), then a flow is established in all of the flushing lines of said zone which corresponds to the synchronicity plus or minus 8%.
