Description
Добавление окисленного петролатума или нейтрализованного окисленного петролатума к раствору депарафинируемых масел в нефти, дихлорэтане и бензоле, ацетоне и бензоле и других растворител х повышает выход масел при депарафинизации на 15-ЗОо/о. Дл ликвидации свободной кислотности окисленный петролатум нейтрализуют сол ми кальци , магни и других металлов. Количество окисленного петролатума или нейтрализованного окисленного петролатума, добавл емого к исходному депарафинируемому продукту составл ет от 0,4 до 20/0.Adding oxidized petrolatum or neutralized oxidized petrolatum to a solution of dewaxed oils in petroleum, dichloroethane and benzene, acetone and benzene and other solvents increases the yield of oils during dewaxing by 15-ZOo / o. To eliminate free acidity, oxidized petrolatum is neutralized with salts of calcium, magnesium, and other metals. The amount of oxidized petrolatum or neutralized oxidized petrolatum added to the initial dewaxed product is from 0.4 to 20/0.
Пример 1. Выход масла после обычной депарафинизации фильтрстока в растворе мазута составл ет 67о/о. Добавление к фильтрстоку 0,80/0 окисленного петролатума повышает выход масла до 80- 820/0.Example 1. The oil yield after the usual dewaxing of the filter stock in the fuel oil solution is 67 ° / o. The addition of oxidized petrolatum to the filter stock of 0.80 / 0 increases the oil yield to 80-820 / 0.
Пример 2. Дипарафинизаци масла из раствора в дихлорэтане и бензоле дает выход масла 68в/о- В присутствии IO/Q окисленного петролатума выход масла повышаетс до 78о/о.Example 2. Dipening of an oil from a solution in dichloroethane and benzene gives an oil yield of 68b / o. In the presence of IO / Q oxidized petrolatum, the oil yield increases to 78 ° / o.
Предмет изобретени Subject invention
Способ депарафинизации нефт ных масел путем охлаждени q применением растворителей, отличаюш;ийс тем, что перед охлаждением нагретого раствора к нему добавл ют от 0,4 до 2о/о окисленно. го петролатума или других окисленных парафинсодержащих продуктов , свободна кислотность которых нейтрализована.The method of dewaxing petroleum oils by cooling q by using solvents is different from that in order to cool the heated solution to it, 0.4 to 2 o / o is oxidized. petrolatum or other oxidized paraffin-containing products, the free acidity of which is neutralized.
