Description
Przedmiotem wynalazku jest sposób usuwania zwiazków siarki i weglowodorów aromaty¬ cznych posiadajacych co najmniej trzy skondensowane pierscienie, z przetworów ropy naftowej.Zmniejszanie zawartosci siarki w przetworacha ropy naftowej posiada duze znaczenie dla ochrony srodowiska. Stosowana zazwyczaj rafinacja kwasem siarkowym jest klopotliwa i powo¬ duje duze straty surowca. Hydrorafinacja z kolei nie zdaje egzaminu w przypadku wyzszych frakcji.Wielopierscieniowe weglowodory usuwa sie znanymi sposobami przez przylaczanie bezwodnika maleinowego i wymywanie alkaliami, lecz jest to metoda zmudna i technicznie nieoplacalna.Sposób wedlug wynalazku polega na wytracaniu nierozpuszczalnych kompleksów z chlor¬ kiem chromylu, CrC^Ck, przy czym tioetery, które stanowia przewazajaca czesc skladników siarkowych ropy, ulegaja wytraceniu w pierwszej kolejnosci. Umozliwia to uzyskanie pierwszej frakcji, zawierajacej tioetery i drugiej, zawierajacej policykliczne weglowodory.Wydzielone sklad¬ niki mozna odzyskac na drodze rozkladu kompleksów woda.Chlorek chronylu stosuje sie w postaci roztworu w eterze naftowym, który przygotowuje sie przez nasycanie suchym chlorowodorem zawiesiny 100 g trójtlenku chromowego w litrze eteru naftowego przy intensywnym mieszaniu. Chlorek chromylu tworzy sie wedlug reakcji: Cr03 + 2 HCl = Cr02Cl2 + H20 Otrzymany produkt rozpuszcza sie w eterze naftowym, dajac krwistoczerwony roztwór, a nieprzereagowany trójtlenek chromu oddziela sie w postaci warstwy wodnej i po wysuszeniu zawraca do procesu. Roztwór chlorku chronylu nalezy przechowywac w obnizonej temperaturze bez dostepu swiatla. Stezenie mozna oznaczyc po rozkladzie próbki woda na drodze jodometry- cznej. Nalezy uwzglednic, ze kompleksy maja sklad molowy 1:1.Wynalazek ilustruje nastepujacy przyklad, w którym procenty oznaczaja procenty wagowe : Przyklad . Do oleju napedowego o zawartosci 0,35% siarki wprowadza sie przy intensyw¬ nym mieszaniu 0,5 molowy roztwór chlorku chromylu w eterze naftowym w ilosci 0,2 litra na litr.Utworzony osad oddziela sie przez odwirownie, rafinat traktuje bezwodna soda i usuwa eter naftowy przez destylacje. W przeliczeniu na wyjsciowy olej zawartosc siarki zostaje zredukowana do 0,05%. W celu oddzielenia policyklicznych weglowodorów wprowadza sie w dalszym ciagu chlorek2 144 570 chromylu do momentu, gdy odczynnik nie bedzie juz stracal osadu z odwirowanej próbki. Osad usuwa sie ponownie przez odwirowanie, a nadmiar chlorku chromylu rozklada sie za pomoca roztworu sody.Zastrzezenie patentowe Sposób usuwania zwiazków siarki i policyklicznych weglowodorów z przetworów ropy naftowej, znamienny tym, ze jako czynnik stracajacy zwiazki siarki i policykliczne weglowodory stosuje sie chlorek chromylu.Pracownia Poligraficzna UP PRL. Naklad 100 egz.Cena 400 zl PLThe present invention relates to a method of removing sulfur compounds and aromatic hydrocarbons having at least three condensed rings from petroleum products. The reduction of the sulfur content in petroleum processing is of great importance for the protection of the environment. The usual sulfuric acid refining is troublesome and causes a great loss of raw material. Hydrotreating, on the other hand, does not work for the higher fractions. Polycyclic hydrocarbons are removed by known methods by attaching maleic anhydride and leaching with alkali, but this is a tedious and technically unprofitable method. Ck, with the thioethers, which constitute the major part of the sulfur components of crude oil, are precipitated first. This makes it possible to obtain the first fraction containing thioethers and the second one containing polycyclic hydrocarbons. The separated components can be recovered by decomposition of the complexes with water. Chronic chloride is used as a solution in light petroleum which is prepared by impregnating a suspension of 100 g of chromium trioxide with dry hydrogen chloride. in liter of petroleum ether with vigorous stirring. Chromyl chloride is formed according to the reaction: CrO3 + 2 HCl = CrO2Cl2 + H20. The obtained product is dissolved in petroleum ether, giving a blood-red solution, and unreacted chromium trioxide is separated as an aqueous layer and recycled to the process after drying. The chronyl chloride solution should be stored at a low temperature and away from light. The concentration can be determined after the decomposition of the sample with water by iodometric method. Note that the complexes have a molar composition of 1: 1. The invention is illustrated by the following example in which percentages are percentages by weight: Example. A 0.5 molar solution of chromyl chloride in petroleum ether, 0.2 liter per liter, is introduced into diesel fuel with a sulfur content of 0.35%. The precipitate formed is separated by centrifugation, the raffinate is treated with anhydrous sodium and the ether is removed. petroleum by distillation. In terms of the original oil, the sulfur content is reduced to 0.05%. In order to separate the polycyclic hydrocarbons, chromyl chloride 2 144 570 is continued to be introduced until the reagent no longer loses sediment from the centrifuged sample. The sediment is removed again by centrifugation, and the excess chromyl chloride is decomposed with a soda solution. Patent claim A method of removing sulfur compounds and polycyclic hydrocarbons from petroleum products, characterized by the fact that chromyl chloride is used as a factor losing sulfur compounds and polycyclic hydrocarbons.
