Determination of halloysites in carbon nanotubes

EXPERİMENTAL PART
Halloysite nanotubes can be applied in nanotechnology in the following areas:
1) Additives to polymer composites
2) Encapsulation and controlled diffusion of biologically active compounds used in medicine and pharmaceuticals
3) Nanocontainers for adding inhibitors to the composition of paints used against corrosion of metals
4) In the purchase of electroactive composites for application in the electronic industry
5) Catalysts for conversion and cracking of hydrocarbons in the oil industry
The analyses conducted show that the composition of halloysite samples taken from different sources is almost the same. A mixture of these samples was taken during the experiments.
X-ray diffractometry (diffractometer XRD TD 3500), X-ray fluorescence microscopy (RFM XGT 7000) and electron paramagnetic resonance (EPR) (radiospectrometer JES-PE-3X, Jeol) were used to study the phase and elemental composition of the halloysite sample. has also been done. The studies were conducted at room and liquid nitrogen temperatures. The thermal properties of these samples were determined using thermographic differential thermal analysis (TQ/DTA/DTQ) method and STА 449F3 Jupiter analyzer manufactured by NETZSCH company of Germany.

RESULT AND DİSCUSSİON
As a result of the literature research given above, it is clear that improving the processes of obtaining low molecular weight olefins and involving heavy oil fractions in thermal and thermocatalytic processes is one of the main issues. It is appropriate to research and find new types of catalysts in thermocatalytic processes, and to use different heating surfaces in thermal processes. On the other hand, taking into account the threat of depletion of oil reserves and the environmental damage caused by the use of oil products, the attraction of new sources of raw materials alternative to oil is currently considered a new direction of the pyrolysis process. As an alternative new raw material, processed vegetable oils that are not used in the food industry are supposed to be used.


CONCLUSİON
1. The presented research study was conducted to study the possibility of obtaining low molecular weight olefins during the threat of thermal and thermocatalytic conversion of heavy fractions of oil into heavy gas oil and vacuum gas oil in a clean state and their 10% cotton oil.
2. The unique properties of halloysites and the effects they can use in full-temperature molecules are used in the study of the process of obtaining S2-S4 lower olefins, that is, in this study, 500-800 oС and 500-650 oС (deep catalytic cracking) halloysite is used as a catalyst, in the temperature range of 600 C .

HALLOİZİTLƏRİN KARBON TİPLİ NANOBORULARDA TƏYİNİ
Həsənxanova N. V., Salahova F. C.
Xülasə: Aşağı molekullu olefinlərin alınmasının müasir tendensiyasında etilenin əldə olunmuş yüksək çıxımını saxlamaqla, propilenin daha çox çıxımla alınmasının təmin edilməsini nəzərə aldıqda geniş temperatur aralığında həm etilenin, həm də propilenin çıxımının kifayət qədər yüksək olmasına imkan verən yeni növ katalizatorların axtarılması problemi yaranır. Bu nöqteyi nəzərdən kimyəvi formulu Al₂Si₂O₅(ОН)₄.2H₂O olan təbii halloizit nanoboruları diqqəti cəlb edir, onların kaolinitdən fərqi isə yanaşı qatlarının arasında əlavə su monoqatının olmasıdır. Onları həmçinin quruluş dövrülüyünə – 10 Å görə halloizitlər-(10 Å) də adlandırırlar.
Açar sözlər: aşağı molekkullu olefinlər, halloizitlər, piroliz, ionizasiya, nanoboru.
