PCT No. PCT/EP97/01993 Sec. 371 Date Oct. 21, 1998 Sec. 102(e) Date Oct. 21, 1998 PCT Filed Apr. 16, 1997 PCT Pub. No. WO97/39994 PCT Pub. Date Oct. 30, 1997A process for selectively removing nitrogenated and/or sulfurated contaminants from streams prevalently containing hydrocarbons with from 3 to 8 crbon atoms characterized in that it comprises an adsorption step wherein said contaminants are adsorbed by an adsorbent essentially consisting of silica gel at a temperature of between 0 and 150 DEG C. and at a pressure of between 1 and 20 atm and a regeneration step to remove the adsorbed substances by thermal treatment in a stream of insert gas carried out at a temperature of between 100 and 200 DEG C.
