Possibility of application of high silicon keolitic catalyst with thermal and mechanochemical treatment for catalytic flavoring of the propane-butane fraction
The studies were carried out in a flow catalytic device in the stationary phase of the catalyst (catalyst volume 6 cm3), at 450–6000C, at normal atmospheric pressure (P = 0.1 MPa), was carried out under conditions in which the volumetric velocity of the initial gas mixture was 600–1000 h-1.

| description | The studies were carried out in a flow catalytic device in the stationary phase of the catalyst (catalyst volume 6 cm3), at 450–6000C, at normal atmospheric pressure (P = 0.1 MPa), was carried out under conditions in which the volumetric velocity of the initial gas mixture was 600–1000 h-1. Qualitative and quantitative composition of propane-butane fraction and reaction products were analyzed on the chromatograph “Chromatic-Crystal 5000M” under the following favorable conditions: separation of gaseous products was carried out in a column thermal conductivity detector (TCD) with a length of 3 m and a diameter of 3 mm filled with 8% NaOH / Al2O3. The separation of liquid products was carried out in a DV-1 capillary quartz column (30 m x 0.25 μm), and detection was carried out in a flame ionization detector. Check the acidity of the catalysts. The acid characteristics of the samples were studied by the method of the programmed desorption of ammonia in the automatic chemisorption analyzer “USGA-101”. X-ray phase analysis: X-ray examination of the samples (X-ray phase analysis) was performed on a diffractometer XRD-6100 (Shimadzu, Japan). Phase identification was performed based on radiographs of individual components (JSPDS card index) based on data from the literature. The purpose of this work is to study the possibility of using thermally and mechanochemically treated high-silicon zeolite catalysts in the catalytic aromatization of the propane-butane fraction and acid properties. |
