Description
Окись азота, всегда присутствующа в коксовом газе в небольших концентраци х , окисл сь в двуокись, реагирует с ненасыщенными углеводородами, дава смолистые вещества, забивающие трубопроводы. Ацетилен реагирует с медными част ми, дава взрывчатую ацетиленистую медь. В течение последних 10-15 лет научно-техническа мысль упорно работала над разрещением проблемы полного удалени окиси азота из коксового газа.Nitric oxide, always present in coke-oven gas in small concentrations, oxidized to dioxide, reacts with unsaturated hydrocarbons to produce resinous materials that clog pipelines. Acetylene reacts with copper parts to produce explosive acetylene copper. During the last 10-15 years, scientific and technical thought has been working hard to solve the problem of complete removal of nitric oxide from coke oven gas.
В насто щее врем удаление окиси азота из коксового газа производитс при одновременной очистке коксового газа от сероводорода болотной рудой,Currently, the removal of nitric oxide from coke oven gas is carried out while simultaneously cleaning the coke oven gas from hydrogen sulfide with marsh ore,
люкс-массой и т, п.lux-mass and m, p.
Однако, полного удалени окиси азота при этом не достигаетс ; кроме того, этот способ требует громоздкой аппаратуры и сложной регенерации отработанных масс.;However, complete removal of nitric oxide is not achieved; in addition, this method requires cumbersome equipment and complex regeneration of waste masses .;
Дл удалени окиси азота из газов, не содержащих сернистых соединений, имеетс целый р д патентов (Клода австр. пат. № 12462, амер. пат. №1919842; франц. пат. № 638382; англ. пат.№ , герм. пат. № 484055), предлага эщихTo remove nitric oxide from gases that do not contain sulfur compounds, there are a number of patents (Claude Austr. Pat. No. 12462, Amer. Pat. No. 1919842; French Pat. No. 638382; Eng. Pat. No., Germ. Pat. No. 484055), offered by
восстановленные металлы-медь и железо .reduced metals — copper and iron.
Эти катализаторы легко отравл ютс сернистыми соединени ми и после этого уже не регенерируютс .These catalysts are easily poisoned with sulfur compounds and are no longer regenerated after that.
Тропш и Касслер (чехосл. пат. № 42928, франц. пат, № 73531) предложили в качестве сероустойчивого катализатора дл очистки коксового газа от окиси азота сульфиды молибдена и вольфрама, известные весьма давно, как гидрирующие катализаторы.Tropsch and Kassler (Czech Pat. No. 42928, French Pat. No. 73531) suggested that molybdenum and tungsten sulfides, known long ago, as hydrogenating catalysts, as a sulfur-resistant catalyst for purifying coke oven gas from nitric oxide.
Эти катализаторы при нашей проверке оказались высокоактивными лишь при температуре 17Ь-200°, кроме того, требуют частой регенерации или большой концентрации сероводорода в исходном газе, и, наконец, довольно дороги и сложны в приготовлении.During our testing, these catalysts turned out to be highly active only at a temperature of 17–200 °; in addition, they require frequent regeneration or a high concentration of hydrogen sulfide in the source gas, and, finally, are quite expensive and difficult to prepare.
В результате исследований авторами найден составл ющий предмет насто щего авторского свидетельства способ очистки коксового fasa от следов окиси азота и ацетилена путем восстановлени и гидрировани в присутствии катализаторов, заключающийс в том, что в качестве последних примен ют сульфиды т желых металлов, как железа , никел , кобальта и меди, приAs a result of the research, the authors found a component of the present author's testimony of a method for purifying coke oven fasa from traces of nitric oxide and acetylene by reduction and hydrogenation in the presence of catalysts, which means that sulfides of heavy metals like iron, nickel, cobalt and copper, with
атмосферном давлении и температуре 70-130°. atmospheric pressure and temperature of 70-130 °.
Процесс может проводитьс и под давлением дй 30 атмосфер при указанной температуре.The process can also be carried out under a pressure of 30 atm at a specified temperature.
При применений катализаторов на производстве достигаетс Ьледующее:With the use of catalysts in production, the following is achieved:
1.Решаетс проблема полного удалени окиси азота и ацетилена из коксового газа и тем самым исключаетс возможность образовани клейких и взрывоопасных веществ.1. The problem of the complete removal of nitric oxide and acetylene from coke oven gas is solved, thereby eliminating the possibility of formation of sticky and explosive substances.
2.Получаете больша экономи по очистке коксового газа, так как исключаютс сероочистные щики и регенераци отработанных масс.2. You get great savings in coke oven gas cleaning, as it eliminates desulfurization drawers and regeneration of waste mass.
3.Проведение очистки газа при температурах 70-130° позвол ет использовать дл этой цели теплоту сжати газа после 2-й и 3-й ступеней компрессора и таким образом исключаютс до13. Carrying out gas cleaning at temperatures of 70-130 ° C allows for this purpose to use the heat of compression of the gas after the 2nd and 3rd stages of the compressor and thus excludes up to 1
