Изобретение относитс к процессуполучени ацетилена термоокислительным пиролизом метана.The invention relates to the process of obtaining acetylene by thermal-oxidative pyrolysis of methane.
Известеч способ получени ацетиена , включающий смешение кислорода со смесью метана, водорода и окиси углерода путем ввода кислорода в смесь газов и подачу образующейс смеси в зону окислительного пчроли-i: за 1.Lime is a method of obtaining acetyene, which includes mixing oxygen with a mixture of methane, hydrogen and carbon monoxide by introducing oxygen into the mixture of gases and feeding the resulting mixture into the zone of oxidative pestrol-i: for 1.
Однако при вводе кислорода в етано-водородную смесь максимгшьно возможна температура получаемой смеси 350-400с. При более высоких температурах происходит воспламенение смеси еще до ввода ее в зону окислительного пиролиза. Низка температура смеси/ подаваемой в зону пиролиза, приводит к низкому выходу продукта и большому сажеобразованию .However, when oxygen is introduced into the ethane-hydrogen mixture, the temperature of the resulting mixture is 350–400 s. At higher temperatures, the mixture ignites before it enters the zone of oxidative pyrolysis. The low temperature of the mixture / feed to the pyrolysis zone leads to a low product yield and high soot formation.
Известен также способ получени ацетилена путем окислительного пироиза метана, включающий смешивание предварительно подогретых до 600700°С метана и кислорода в мольном соотношении ,55 - 0,65, ввод етано-кислородной смеси в зону кислительного пиролиза и смешивание с водородом или водородсодержащим газом 2.There is also known a method for producing acetylene by oxidative pyrolysis of methane, which includes mixing methane and oxygen preheated to 600700 ° C in a molar ratio of 55-0.65, introducing ethane-oxygen mixture into the acidifying pyrolysis zone and mixing with hydrogen or hydrogen-containing gas 2.
Воспламенение смеси происходит в момент добавлени водорода и реакци окислительного пиролиза метана протекает в так называемой области диффузионного горени .The mixture ignites at the moment hydrogen is added and the oxidative pyrolysis of methane takes place in the so-called diffusion burning region.
Однако при осуществлении способа окислительного пиролиза в диффу0 зионном пламени в промышленных реакторах больших габаритов наблюдаютс отдельные зоны с резко повышенной температурой до 2000 С, что приводит к разложению образовавшего5 с ацетилена и, следовательно, к снижению выхода продукта..However, in the implementation of the method of oxidative pyrolysis in a diffusion flame in industrial reactors of large dimensions, separate zones are observed with a sharply elevated temperature of up to 2000 ° C, which leads to decomposition of the formed 5 with acetylene and, consequently, to a decrease in product yield.
Кроме того, наличие местных зон перегрева часто приводит к оплавлению стенок реактора и нарушению 0 процесса.In addition, the presence of local overheating zones often leads to melting of the reactor walls and disruption of the process.
Цель изобретени - повышение выхода продукта при осуществлении процесса в промышленных реакторах.The purpose of the invention is to increase the yield of the product in the implementation process in industrial reactors.
