способа ускорени процесса получени асфальта продувкой нефт ных гудроной воздухом.A method for speeding up the asphalt process by flushing oil with tar.
К патенту Г. Л. Шапиро, за вленному 17 нюн - 1925 года (за в. свид. JvS 3876).To the patent of G.L. Shapiro, for the value of 17 Nun - 1925 (for V. ed. JvS 3876).
О выдаче патента опубликовано 31 нвара 1980 года. Действие патента -распростран етс на 15 лет от 31 нва 1930 года.On issuing a patent published 31 Nvara 1980. The patent is valid for 15 years dated January 31, 1930.
I Щримен ющиес в нагето щее врем способы приготовлени асфа.1ьта путем продолжительного продувани остатков перегонки нефти или мазута (гудрона) нагретым воздухом имеют существенные недостатки, заключающиес в том, что продувка продолжаетс очень долго (до 120-ти часов) и получаемый асфальт при достаточно высокой точке плавлени обладает сильной проницаемостью.The superimposed methods of preparing asphalt by prolonged blowing of the distillation of oil or fuel oil (tar) with heated air have significant drawbacks in that the blowing takes a very long time (up to 120 hours) and the asphalt obtained is sufficient. high melting point has strong permeability.
В предлагаемом способе получение асфа,льта из гудронов, ускорение процесса производства, улучшение качества продукта и использование кислых отбросов посредством продувки воздухом достигаетс тем, что к исходному материалу прибавл етс кислый гудрон, отмытый (общеизвестными способами) от серной кислоты. Добавл емый кислый гудрон таким образом играет роль ускорител процесса, уменьша скрытый период окислени .In the proposed method, the production of aspha, lt from tars, the acceleration of the production process, the improvement of the quality of the product and the use of acidic waste by blowing through air is achieved by adding to the starting material acidic sludge washed (by common methods) from sulfuric acid. The added acidic tar thus plays the role of a process accelerator, reducing the latent period of oxidation.
При продувке гудрона изменение свойств (точки плавлени и проницаемости ) получаемого продукта (асфальта ) происходит медленнее в натовWhen tar is blown, the change in properties (melting point and permeability) of the obtained product (asphalt) occurs more slowly in natas.
чале и быстрее в конце. Объ сн етс это тем,/что образующиес постепенно с начала продувки продукты окислени и полимеризации действуют ускор юще на дальнейшее реагирование еще не изменившихс частей. Освобожденные от кислоты вислые нефт ные отбросы содержат в себе непредедьные соединени , которые окисл ютс и полимернзуютс в нервые ase часы продувки, даъа продукты , также увеличивающие дальнейшую сксфость превращени в асфальт. Таким образом, прибавление отмытых от йислоты вислых нефт ных отбросов с одной стороны действует как бы каталитически на происход щее продёссь, с другой-улучшает качество получаемого асфальта. Явление B-io аналогично общеизвестному влению хн11ической индукции.chalet and faster at the end. This is explained by the fact that the oxidation and polymerization products formed gradually from the beginning of the purge act to accelerate the further reaction of the parts that have not yet changed. Acid-free oil droplets contain impure compounds that oxidize and polymerize during the first time ase hours of purging, and products that also increase the subsequent conversion to asphalt. Thus, the addition of peeled oil debris washed from an acid, on the one hand, acts, as it were, catalytically on the progress of the project, on the other hand, it improves the quality of the asphalt produced. The B-io phenomenon is similar to the well-known phenomenon of chemical induction.
Освобождение кислых нефт ных отбросов от содержащейс в них серной кислоты может быть произведено разЖЕЧныни способами: а) кислые отбросы раствор ютс в каком-нибудь аромагаческом растворителе. Оседающа при растворении кислота снускаетс . Полученный раствор органической части кислых отбросов промываетс водой дл удалени оставшейс в нем КИСЛОТЫ, носле чего растворитель отгон етс ; б) неоднократной промывкой кислых отбросов водой; в) нейтрализацией кислоты в кислых отбросах химическими реагентами и другими способами.The release of acidic oil debris from the sulfuric acid contained in them can be carried out by explosive methods: a) The acidic waste is dissolved in some aromatic solvent. The acid that precipitates upon dissolution is discharged. The resulting solution of the organic part of the acid waste is washed with water to remove the remaining ACID in it, and the solvent is distilled off; b) repeated washing of acidic waste with water; c) neutralization of acid in acidic waste by chemical reagents and other methods.
