“…The outcome of this study confirmed that this hybrid material is more stable and displayed a higher selectivity to C 8 hydrocarbons and TMP over time, in comparison with pure sulfated zirconium dioxide. 91 Therefore, the hybrid catalysts are a promising candidate in the development of the industrial alkylation process. Whereas mixed oxides have been featured to some extent for alkylation reaction, it can be barely found reports mentioned bimetallic catalysts being prepared in the most favorable ways; one might have thought that combinations have been especially interesting to improve alkylation catalysts.…”

“…Somewhat more promising outcomes are found with hybrid catalysts (metals supported on zeolite). Yuferova et al carried out a study on the alkylation of isobutane with isobutylene over hybrid material of 4 wt% sulfated zirconium dioxide supported on H-beta zeolite. The outcome of this study confirmed that this hybrid material is more stable and displayed a higher selectivity to C 8 hydrocarbons and TMP over time, in comparison with pure sulfated zirconium dioxide .…”

New Insights into the Progress on the Isobutane/Butene Alkylation Reaction and Related Processes for High-Quality Fuel Production. A Critical Review

Although research in renewables is growing at a tremendous rate, the world will still be greatly dependent on fossil fuels for at least the first half of this century. In the quest for more efficient and clean fuels, oil refining companies have turned their attention to processes such as reforming and alkylation technologies; in the latter process, isobutane is reacted with butenes and/or propylenes to produce, among others, branched isooctane, which is the main high-octane component of the gasoline pool. The main benefit of this process is the possibility to produce sulfur-free high-octane fuels, so important economic and environmental advantages are foreseen if investments in this area are realized. This Review analyzes and discusses the most recent progress on catalyst technologies, starting from the traditional sulfuric acid process and proceeding to newly emerging catalyst technologies such as solid acid and ionic liquid-based catalysts. We start with basic mechanistic analyses and conclude this Review with the new nonliquid acid-based commercial and emerging technologies for isobutane alkylation. Emphasis is given to the structure−activity relationships and the advantages and disadvantages present in every discussed catalyst material.

“…To this day, amorphous zirconium dioxide is widely used as a catalyst in various chemical processes [1,8,13]. Such processes can be the light naphtha isomerization [4][5][6][7], as well as the synthesis of polystyrene, methanol [12,15], dimethyl ether [17] and other important compounds [11,14,18,19]. All these processes are relevant for modern industry.…”

The article presents the results of studies on preparation of amorphous zirconium dioxide from zirconium nitrate by its hydrolysis in the presence of oxalic acid. It is determined that the balance of reagents taken for synthesis (1 ml 0,025 M ZrO(NO3)2 is 1.35 ml 4 M HOOC-COOH), and the optimum temperature of the received gel drying, which is 230 ̊С, is established, too. Morphology of the obtained ZrO2 samples was explored. It has been found that the calcining temperature is independent of the size and shape forming irregular agglomerates, consisting of smaller spherical particles, whose diameter varies between 50 and 300 nm. The X-ray analysis of the sample is represented, which showed a low degree of crystallinity of the substance. IR spectroscopy data showed the presence of zirconium dioxide-characteristic peaks on the IR spectrum. The same spectrum reflects the presence of a large amount of sorbed water in the obtained sample, as well as peaks characteristic of the gas adsorbed by the sample from the environment.
