Claim 6:
7. The process according to claim 4, where the amino compound, or the mixture of the amino compounds, is activated through distillation, comprising:
preparing a solution with variable concentration between 40 and 60% m/v of amino compound, or of the mixture of the amino compounds, and feeding it into a distiller;
separately preparing a lead paste suspension with water, with a liquid/solid ratio m/m between 0.5 and 2 and feeding it to a reactor;
starting a distillation of the amino compound solution or of the mixture of the amino compounds, at a temperature between 140° C. and 190° C. and pressure between 4 and 10 atm; and
conveying the obtained distillate, optionally condensed, into the reactor containing the lead paste suspension to finalize the desulphurization reaction initially at ambient temperature and atmospheric pressure.
