Annotatsiya

Cyclization products can be 5- or 6-membered ring compounds. The reactions leading to the formation of these hydrocarbons represent and -cyclization reactions. Platinum catalysts for the dehydrogenation of paraffins are highly dispersed multicomponent systems embedded in a heat-resistant oxide support with a developed surface. The concentration of platinum and promoters usually does not exceed 1% wt. The most common support is γ-alumina. Previously, similar platinum catalysts were widely used in the low-pressure reforming process. This allows us to explain the high efficiency of bimetallic aluminum-platinum dehydrogenation catalysts, which is maintained even with coke content of more than 10% by weight of the catalyst. In the synthesis of aromatic hydrocarbons based on synthetic naphtha, it was proven that the samples converted to aromatic hydrocarbons in the first pass when using the catalytic systems Cr2O7 catalyst and AlNiMo+bentonite catalyst. The combined use of these catalysts resulted in the formation of monoaromatic hydrocarbons from a mixture of naphtha hydrocarbons with a high mass fraction of n-hexane, n-heptane, and n-octane in high yield and demonstrated high selectivity for this synthesis.
