Description
Известен способ пиролиза углеводородного сырь , по которому, с целью снижени коксообразовани , пиролиз проводитс в присутствии толуола.There is a known method for the pyrolysis of a hydrocarbon feedstock, according to which, in order to reduce coke formation, pyrolysis is carried out in the presence of toluene.
Предлагаемый способ совместного пиролиза этана (или других легких углеводородов) с толуолом отличаетс от известного способа тем, что процесс проводитс при мол рном соотношении компонентов, равном 4: 1. При этом одновременно протекают две основные реакции - термическое дегидрирование этана в этилен и гидродеалкилирование толуола:The proposed method of co-pyrolysis of ethane (or other light hydrocarbons) with toluene differs from the known method in that the process is carried out with a molar ratio of components of 4: 1. At the same time, two main reactions occur - thermal dehydrogenation of ethane to ethylene and hydrodealkylation of toluene:
СбН5СНз + Н2- СбНб + СН4(2)SbN5SNz + H2-SbNb + CH4 (2)
Таким образом, часть водорода, выдел ющегос по реакции (1), расходуетс в реакции (2), что способствует увеличению конверсии этана. С другой стороны, водород в момент выделени увеличивает скорость гидродеалкилировани толуола.Thus, part of the hydrogen released by reaction (1) is consumed in reaction (2), which contributes to an increase in ethane conversion. On the other hand, hydrogen at the time of release increases the rate of hydrodealkylation of toluene.
Процесс одновременного получени этилена и бензола может проводитьс в типовых трубчатых пиролизных печах, а также на установках с циркулирующим теплоносителем.The process of simultaneous production of ethylene and benzene can be carried out in typical tubular pyrolysis furnaces, as well as in installations with a circulating coolant.
Пример 1. Смесь этановой фракции и толуола в мол рном отношении 4 мол этана на 1 моль толуола подвергалась пиролизу при температуре 820°, времени контакта 0,8 сек и атмосферном давлении. Реакци проводилась в кварцевом реакторе. Состав исходного газа и газа пиролиза приведены в таблице 1.Example 1. A mixture of ethane fraction and toluene in a molar ratio of 4 mol of ethane per 1 mol of toluene was subjected to pyrolysis at a temperature of 820 °, contact time of 0.8 sec and atmospheric pressure. The reaction was carried out in a quartz reactor. The composition of the source gas and pyrolysis gas are shown in table 1.
