Description
Изобретение относитс к способу одновременного получени пропилена и изопентана.This invention relates to a process for the simultaneous production of propylene and isopentane.
Известен способ одновременного получени олефиновых и изопарафиновых углеводородов путем пропорционировани парафиновых углеводородов, например н-бутана, в присутствии катализатора - рутени , платины или паллади на молекул рных ситах и вод ного пара при 535-700°С.A known method for the simultaneous production of olefinic and isoparaffinic hydrocarbons by proportional paraffinic hydrocarbons, for example n-butane, in the presence of a catalyst — ruthenium, platinum or palladium on molecular sieves and water vapor at 535-700 ° C.
Недостатком известного способа вл етс проведение реакции при высоком давлении (100 атм), что значительно усложн ет процесс .The disadvantage of this method is to carry out the reaction at high pressure (100 atm), which significantly complicates the process.
С целью упрощени процесса предлагаетс в качестве катализатора использовать кальцийкалийникельхромалюмофосфатный катализатор .In order to simplify the process, it is proposed to use a calcium potassium nickel chromium aluminum phosphate catalyst as a catalyst.
Этот катализатор испытывают на лабораторной установке с разбавлением н-бутана вод ным паром и без разбавлени .This catalyst is tested in a laboratory setup with dilution of n-butane with and without dilution.
Стабильна активность катализатора достигаетс через 35-40 час его работы и затем не мен етс в течение года.A stable activity of the catalyst is reached after 35-40 hours of its operation and then does not change during the year.
Испытываемый катализатор содержит (вес.%): 0,9-6,0 NiO, 7,8-13,9 СггОз, 4,5- 24,0 РгОй, 37,2-86,0 , 2,6-23,0 СаО и 1,8-2,0 К20.The test catalyst contains (wt.%): 0.9-6.0 NiO, 7.8-13.9 CrgOz, 4.5- 24.0 PgOi, 37.2-86.0, 2.6- 23, 0 CaO and 1.8-2.0 K20.
Пример 1. Через реактор со стационарны .м слоем (30 мл) кальцийкалийникельхромалюмофосфатного катализатора пропускают н-бутан, разбавленный вод ным паром (1:7), с объемной скоростью 400 при температуре 600-620°С.Example 1. A n-butane diluted with water vapor (1: 7) is passed through a reactor with a stationary calcium layer (30 ml) of calcium and a nickel-chromium-alumino-phosphate catalyst with a bulk velocity of 400 at a temperature of 600-620 ° C.
Состав полученного контактного газа прнведен в табл. 1.The composition of the obtained contact gas is presented in Table. one.
Пример 2. Провод т опыт, как и в примере 1, пропуска н-бутан при температуре 575 и 600°С с объемной скоростью 400 . Состав получепного контактного газа приведен в табл. 2.Example 2. The experiment was carried out, as in Example 1, of passing n-butane at a temperature of 575 and 600 ° C with a bulk velocity of 400. The composition of the final contact gas is given in table. 2
Таблица 1Table 1
Как видно из данных, приведенных в табл. 1 и табл. 2, реакци диснропорционировани н-бутана в присутствии вод ного пара и без него протекает в основном по следующей схеме:As can be seen from the data given in table. 1 and tab. 2, the disproportionation reaction of n-butane in the presence of water vapor and without it proceeds mainly according to the following scheme:
.иЗа С5Н,7+ СьНб + Н2.iZa С5Н, 7 + СьНб + Н2
,Hi,Hi
2С2Н4 + 2С2Нб2С2Н4 + 2С2Нб
Таким образом, 30-40% пропущенного н-бутана вступает в реакцию дегидродиспропорционировани , при которой выход пропилена и изопентапа на прореагировавпиий н-бутан составл ет 20-28% соответственно.Thus, 30-40% of the missed n-butane enters into a dehydrodisposing reaction, in which the yield of propylene and isopentap on the unreacted n-butane is 20-28%, respectively.
Предмет изобретени Subject invention
Способ одновременного получени пропилена и изопентана диспропорционированием н-бутана при повышенной температуре в присутствии катализатора, отличающийс тем, что, с целью упрощени процесса, в качестве катализатора используют кальцийкалийникельхромалюмофосфатный катализатор.A process for the simultaneous production of propylene and isopentane by disproportionating n-butane at elevated temperature in the presence of a catalyst, characterized in that, in order to simplify the process, calcium and copper chromo-alumino phosphate catalysts are used as a catalyst.
