Prediction of the catalytic activity of Ni-Al mixed oxide in the hydroisomerization of n-alkanes

Abstract

This article discusses the possibility of using mixed Ni-Al oxides as catalyst systems for the hydroisomerization of n-alkanes. A number of instrumental analysis methods were carried out, on the basis of which elementary lattices of the synthesized mixed oxides were modeled. A preliminary study showed that systems based on mixed Ni-Al oxides have acidic, basic properties. Their structure makes it possible to speak of the presence of molecular sieve properties, which will make it possible to obtain mono- and dimethyl substituted isoalkanes, which will lower the pour point of diesel fuel and at the same time produce high-acetane products. According to preliminary data, the best result is shown by a sample of mixed Ni-Al oxide with a ratio of Ni2+/Al3+ cations equal to two in the synthesis.
