Изобретение относитс к технике производства углеродных веществ, в частности нефт ного кокса.This invention relates to a technique for producing carbonaceous substances, in particular petroleum coke.
Известен способ нодготовки углеводородного сырь дл коксовани путем предварительного окислени его, например, серной кислотой с последуюш,им нагревом смеси. Недостатком такого способа вл етс низкий (38,5 вес. %) выход кокса с относительно высоким (0,89 вес. %) содержанием серы.There is a known method of preparing hydrocarbon feedstocks for coking by pre-oxidizing it, for example, with sulfuric acid, followed by heating the mixture. The disadvantage of this method is the low (38.5 wt.%) Yield of coke with a relatively high (0.89 wt.%) Sulfur content.
С целью устранени указанного недостатка по предлагаемому способу нагрев осуществл ют потоком исходного сырь с температурой 300-400°С.In order to eliminate this drawback according to the proposed method, the heating is carried out with a flow of the feedstock with a temperature of 300-400 ° C.
П р п М е р. Углеводородное сырье, например остаток перегопки смол пиролиза углеводородных газов, подают в смеситель, куда одновременно ввод т 96%-ную серную кислоту или содержащую ее продукт в количестве 15%. Из смесител смесь поступает в смеситель-газосепаратор , где ее смешивают с нагретым потоком циркулирующих продуктов с температурой 300-400°С.PR M mere. Hydrocarbons, such as the remainder of the reheating of the pyrolysis resin of hydrocarbon gases, are fed to a mixer, where 96% sulfuric acid or a product containing it in an amount of 15% are simultaneously introduced. From the mixer, the mixture enters the mixer-gas separator, where it is mixed with a heated stream of circulating products with a temperature of 300-400 ° C.
В результате проведени такого процесса выход кокса составл ет 56,9 вес. % и содержание серы в нем 0,35 вес. %.As a result of this process, the coke yield is 56.9 wt. % and its sulfur content of 0.35 weight. %
Предмет изобретени Subject invention
Способ подготовки углеводородного сырь дл коксовани путем предварительного окислени , например, серной кислотой с последующим нагревом, отличающийс те-м, что, с целью увеличени выхода кокса, нагрев осуществл ют потоком исходного сырь с температурой 300-400°С.A method of preparing a hydrocarbon feedstock for coking by pre-oxidation, for example, with sulfuric acid followed by heating, characterized in that, in order to increase the yield of coke, the heating is carried out by the flow of the feedstock with a temperature of 300-400 ° C.
