Description
Готовый катализатор содержит 3 вес. % платины.The finished catalyst contains 3 wt. % platinum.
Б. Испытание катализатора. Опыты провод т в микрокаталитической установке с импульсной подачей исходного углеводорода . В реактор загружают 40 мг (содержание платины 1,2 мг) платиноуглеродного волокна. Углеводород ввод т в реактор импульсами по 120 мкл. Скорость газаносител (водород) составл ет 2000 .мл/час. Продукты реакции поступают в капилл рный хроматограф с пламенно-ионизационным детектором .B. Test catalyst. The experiments were carried out in a microcatalytic installation with a pulsed feed of the initial hydrocarbon. Charged to the reactor 40 mg (platinum content 1.2 mg) of platinum carbon fiber. Hydrocarbon is introduced into the reactor in pulses of 120 µl. The gas carrier rate (hydrogen) is 2000 ml / hour. The reaction products enter a capillary chromatograph with a flame ionization detector.

Благодар иапользоваиию в (качестве носител в предлагаемом катализаторе пиролитического углеродного волокна катализатор обладает высокой газопроницаемостью сло , доступностью активной фазы (платины) мочекулам реагирующих веществ. Платина в высокодисперсном состо нии равномерно распредел етс по объему катализатора и жестко фиксируетс в угольной матрице, что обеспечивает высокую активность и термостабильность катализатора. Катализатор можно получать в различных формах (волокно, ткань, лента, фильтр и т. д.)Due to its use (as a carrier in the proposed pyrolytic carbon fiber catalyst, the catalyst has a high gas permeability layer, the availability of the active phase (platinum) to reactant substances). Platinum in a highly dispersed state is uniformly distributed throughout the catalyst and is rigidly fixed in the carbon matrix, which ensures high activity and thermal stability of the catalyst. The catalyst can be obtained in various forms (fiber, cloth, tape, filter, etc.)
