Claims (4)

1. Способ очистки бензинов от меркаптанов путем их адсорбции с последующей регенерацией адсорбента путем окисления адсорбированных меркаптанов кислородсодержащим газом при нагреве в присутствии катализатора окисления и щелочи и отмывкой адсорбента углеводородом, отличающийся тем, что с целью повышения глубины очистки и сохранения высокой степени очистки при длительной работе адсорбента в качестве адсорбента используют активированные углеродно-волокнистые материалы (АУВМ).1. The method of purification of gasolines from mercaptans by adsorption with subsequent regeneration of the adsorbent by oxidizing the adsorbed mercaptans with an oxygen-containing gas when heated in the presence of an oxidation catalyst and alkali and washing the adsorbent with hydrocarbon, characterized in that in order to increase the purification depth and maintain a high degree of purification during long-term operation adsorbent as an adsorbent using activated carbon fiber materials (AUM). 2. Способ по п.1, отличающийся тем, что регенерацию адсорбента проводят при температуре 70oС.2. The method according to claim 1, characterized in that the regeneration of the adsorbent is carried out at a temperature of 70 o C. 3. Способ по п.1, отличающийся тем, что отмывка адсорбента от дисульфидов производится н-пентаном. 3. The method according to claim 1, characterized in that the washing of the adsorbent from disulfides is made by n-pentane. 4. Способ по п.1, отличающийся тем, что после регенерации и отмывки адсорбент обрабатывают раствором сульфида натрия для удаления адсорбированного кислорода. 4. The method according to claim 1, characterized in that after regeneration and washing, the adsorbent is treated with a solution of sodium sulfide to remove adsorbed oxygen.
