Description

(54) СПОСОБ ПОЛУЧЕНИЯ ВОССТАНОВИТЕЛЬНОГО ГАЗА Изобретение относитс  к пр мому получению железа из классифицированной по крупности или окомкованных же лезных руд, в частности к способу по лучени  восстановительного газа путем вод ной конверсии углеводородного газа с использованием катализатора . Известен способ получени  восстановительногЬ газа путем вод ной паро вой конверсии углеводородного газа с использованием катализатора, включаю щий частичное использование отход ще го дл  этой цели газа, причем, в качестве катализатора может быть использован никель, отход щий газ пере его обработкой подвергают очистке с последующим охлаждением, сушкой, и компрессированием. К недостаткам этого способа относитс  недостаточное поддержание моль ного отношени  ингредиентов восстано вительного газа и избыточное количество вод ного пара. С целью интенсификации процесса восстановлени  классифицированной железной руды конверсию газа ведут при мольном отношении пара к углероду (0,9-1,8): до содержани  водород . и окиси углерода равным 85-98% и бъемного отношени  между ними соответственно 2 к 1, при этом объем паров воды в газе составл ет 1-14%. Сущность способа заключаетс  в том, то исключен воздух из подводимой смеси. Исключение воздуха из подводимой смеси и низкое соотношение пара к углероду в полученной в генераторе , подводимой смеси по насто щему способу приводит к получению восстановительной газовой смеси, содержащей относительно небольшое количество вод ного пара и по крайней мере 85% по объему водорода, плюс окись углерода. Объемное соотношение водорода к окиси углерода восстановительной газовой атмосферы, полученной при низком соотношении пара к углероду в присутствии эффективного катализатора , составл ет по крайней мере 2:1, благодар  чему обеспечиваетс  быстрое восстановление железных руд. Восстановительную газовую смесь передают непосредственно к восстановительной секции шахтной печи, поскольку относительно низкое содержание влаги в смеси исключает необходимость охлаждени  и конденсации вод ного пара.
Можно примен ть соотношени  пара к уплероду от 0,9:1 до 1„8:1 при этом предпочтительным диапазоном  вл етс  от 1,2:1 до 1, б 31. Если отложение углерода в конверторе не составл ет проблему, поскольку в верхней части используетс  очень прочный относительно медленно действуквднй катализатор , который преп тствует разрыву при отложении углерода, то можно примен ть отношение пар-углерод от 0,9:1 до 0,95:1. По всему вьшкэукаэанному диапазону отношений пар-углерод улучшенна  восстановительна  газова  смесь содержит 85-98% по объему окиси углерода и водорода,, Вод ной пар находитс  в пределе пор дт ка 1% по объему, при соотношении паруглерод 0,9:1 и приблизительно до 14% по объему при соотношении паруглерод 1,8:1. Объемное отношение водорода и окиси углерода составл ет 2jl, а в предпочтительном рабочем диапазоне составл ет 3:1. Отход щий газ не рециркулируетс  через слой катализатора и следовательно избегаетс  его серное отравление.
