Изобретение относится к химической промышленности, а именно к технике осушки и очистки экологически чистых углеводородных газов - пропеллентов и может быть использовано в газовой, нефтехимической, а также бытовой химии. Способ получения углеводородных пропеллентов включает комплексную осушку и очистку углеводородного сырья и выделение композиции углеводородного пропеллента. В качестве углеводородного сырья используют пропанбутановую фракцию, или изобутан, или н-бутан, или пропан, или смесь пропана и н-бутана. Осушку и очистку осуществляют путем пропускания сырья в жидкой фазе через сорбенты в трех последовательно расположенных адсорберах. Первый по ходу технологического процесса адсорбер заполнен оксидом алюминия, второй по ходу технологического процесса адсорбер заполнен цеолитом NaA, а третий по ходу технологического процесса адсорбер заполнен цеолитом NaX. Заданную композицию пропеллента получают после третьего по ходу адсорбера, причем в случае использования в качестве углеводородного ...
