A method of producing ammonium phosphates from at least one mineral containing phosphate and an element which is calcium, magnesium, iron, or aluminum. The method includes contacting the at least one mineral (or a combination of them) with a cation exchanger for a time and at a temperature sufficient to yield phosphoric acid from the mineral.

The present disclosure is intended to provide an electrolyzer capable of selectively recovering lithium. The electrolyzer recovers lithium ions Li.sup.+ from a material M. The electrolyzer includes: a pair of electrodes; and a cation exchange membrane provided between the pair of electrodes and having a lithium ion conductivity. The cation exchange membrane allows, among cations contained in the material M, more lithium ions Li.sup.+ to pass therethrough than other cations Ca.sup.2+ and Na.sup.+. The electrolyzer is configured to apply a voltage between the pair of electrodes.

The invention relates to a process for performing a aqueous synthesis of titanium phosphates (TiP) having solely —H2PO4 groups, which process is characterised by the following steps: providing titanium (IV) oxysulphate, TiOSO4, in an aqueous solution or in a powder and H2SO4, substantially without transition divalent metal ions, including cobalt (II) and copper (II), heating N of the thus formed aqueous solution to above 50° C., but below 85° C. for at least 30 minutes, providing a controlled amount of H3PO4 to said aqueous solution, to form an aqueous solution containing a molar ratio between TIO2 and P2Os being controlled to about 1:1, pot not above 1:1.5 and not below 1:0.7, stirring the thus formed aqueous solution for at least 3 hours to form precipitates of titanium Got phosphate, and allowing ageing of said solution, without stirring, acidic washing of the formed precipitate using HCl or other acids to obtain TiO(OH)(H2PO4)-H2O having solely —H2PO4 ion-exchange chemical groups and allowing said precipitates to dry to a powder product, substituting protons in the powder product TiO(OH)(H2PO4)-H2O to sodium cations by treatment of the latter with solutions of sodium carbonate and allowing the thus formed powder of Na—TiP1 to dry.

A process where external fuel oil is used to wash entrained catalyst from a fluidized-bed propane dehydrogenation reactor effluent, where the fuel oil and catalyst mixture is returned to the reactor to provide the net fuel required for catalyst regeneration. Optionally the fluidized-bed propane dehydrogenation reactor effluent and the fuel oil are contacted in a direct contact inline device before entering a flash zone in the reactor vessel.
