Изобретение относитс к адсорбентам дл газовой хроматографии и может быть использовано при анализе перманентных газов и легких углеводородов, The invention relates to adsorbents for gas chromatography and can be used in the analysis of permanent gases and light hydrocarbons,
Целью изобретени вл етс повьппе- ние разделительной способности адсорбента при анализе газов, содержащих ле|гкие углеводороды.The aim of the invention is to increase the separation capacity of the adsorbent in the analysis of gases containing light hydrocarbons.
Пример 1. 100 г силикагел .мфки КСС-4 измельчают и отбирают фракцию 0,15-0,20 мм. Адсорбент про- мьйвают проточной и дистиллированной во|дой и нейтрализуют поверхность 1%- HbJM раствором щелочи. Силикагель проналивают при 400 С в течение 3 ч в му фельной печи. Затем температуру снижают до и помещают в печь вцсушенные брусочки древесины сосны paisMepoM ,,5 см в количестве 10|0 г. Через 10 мин начинают помеши- BaJTb силикагель, а через 30 мин сили- кйгель извлекают и помещают в вакуум- нЫй шкаф дл стабилизации. Стабилизащфо провод т при в течение 4 ч и давлении 1 Па. Полученный адсорбент просеивают, отбира фракцию 0,15 0,2 мм, и заполн ют им колонку длиной 3 :м и внутренним диаметром 3 мм. Анализ газовой смеси осуществл ют с программированием температуры 20-100. С со скоростью 32° в минуту. Программу В14лючают после выхода метана. Детектор аргонрво-ионизационный, скорость Г4за-носител аргона 50 мл/мин. 06- продолжительность анализа 20 мин Пор док выхода компонентов следующий: водород, воздух (азот+кислород), окись углерода, метан, этан, двуокись углерода, этилен, ацетилен, пропилен, пентан.Example 1. 100 g of silica gel KFS-4 grind and select a fraction of 0.15-0.20 mm. The adsorbent is washed with running and distilled water and the surface is neutralized with 1% HbJM alkali solution. Silica gel is perforated at 400 ° C for 3 hours in a muffle oven. Then the temperature is reduced to and placed in the oven, dried pine wood bars pais MepoM ,, 5 cm in an amount of 10 | 0 g. After 10 minutes, the BaJTb silica gel is started, and after 30 minutes the silica gel is removed and placed in a vacuum cabinet for stabilization. . Stabilized at 4 hours and at a pressure of 1 Pa. The resulting adsorbent is sieved, taking a fraction of 0.15 to 0.2 mm, and filling the column with a length of 3: m and an internal diameter of 3 mm. The gas mixture analysis is carried out with temperature programming 20-100. With a speed of 32 ° per minute. The program includes after the release of methane. Argon ionization detector, G4za-argon carrier rate 50 ml / min. 06- analysis time 20 min. The order of the components is as follows: hydrogen, air (nitrogen + oxygen), carbon monoxide, methane, ethane, carbon dioxide, ethylene, acetylene, propylene, pentane.
Пример 2. В услови х примера 1 измен ют врем и температуру обработки силикагел продуктами дест- рукции сосны. Результаты представлены в таблице.Example 2. Under the conditions of Example 1, the time and temperature for treating silica gel with pine destruction products is changed. The results are presented in the table.

Температура менее недостаточна дл деструкции древесины, менее ,чем за 30 мин продукты деструкции не успевают равномерно модифицировать силикагель. Повышение температуры обработки снижает разделительную способность ниже уровй известного способа. .The temperature is less insufficient for the destruction of wood; in less than 30 minutes the degradation products do not have time to evenly modify the silica gel. Increasing the processing temperature reduces the separation capacity below the levels of the known method. .
