Description
Отличительна особенность предлагаемого способа непрерывного гидрировани полициклических углеводородов (нафталина) над молибденовым катализатором состоит в том, что процесс гидрировани осуществл ют так, чтобы активна поверхность катализатора была покрыта жидким продуктом и не соприкасалась с богатой водородом парогазовой смесью. Процесс гидрировани нафталина осуществл ют при температуре, не превыщающей 450°, с пониженной подачей воаорода , примен дл улучшени диффузии водорода, растворенного в жидком продукте, тарельчатые насадки, чем исключаетс возможность гидрировапи нафталина в паровой фазе. Этот принцип применим также дл гидрировани других аналогичных продуктов, например, каменноугольных масел, состо щих из гомологов пафталпна, фенантрена, антрацена и других полициклических углеводородов.A distinctive feature of the proposed method of continuous hydrogenation of polycyclic hydrocarbons (naphthalene) over a molybdenum catalyst is that the hydrogenation process is carried out so that the active surface of the catalyst is covered with a liquid product and does not come into contact with the hydrogen-rich vapor-gas mixture. The process of hydrogenation of naphthalene is carried out at a temperature not exceeding 450 °, with a reduced supply of hydrogen, used to improve the diffusion of hydrogen dissolved in the liquid product, plate-shaped nozzles, which eliminates the possibility of hydrogenation of naphthalene in the vapor phase. This principle is also applicable to the hydrogenation of other similar products, such as coal oils, composed of homologues of paftalpne, phenanthrene, anthracene, and other polycyclic hydrocarbons.
Пример. Смесь сырого нафталина с водородом в молекул рном соотношении 1:4 пропускаетс над катализатором под давлением 200 ат при 425°; подача нафталина составл ет 5 т иа 1 м катализатора в час; получаемый сырой тетралин содержит 35% тетралина и не г.ыше 0,3% декалина.Example. A mixture of crude naphthalene with hydrogen in a molecular ratio of 1: 4 is passed over the catalyst under a pressure of 200 at at 425 °; the naphthalene feed is 5 tons and 1 m of catalyst per hour; the crude tetralin obtained contains 35% tetralin and not more than 0.3% decalin.
При использовании иасадочных тарелок молекул рное соотношение сырь к водороду повыщаетс до 1:2.When using yasadochny plates the molecular ratio of raw materials to hydrogen rises to 1: 2.
