The relationships of the formation of aluminum oxide from aluminum hydroxide peptized with organic acids (propionic, maleic, malonic, tartaric) were studied. The pore structure parameters of the hydroxide samples and of aluminum oxide samples obtaine

The effect of treating aluminum oxide with organic acids (acetic acid, oxalic acid) on the dispersity, composition, and catalytic properties of the platinum sites of reforming catalysts is investigated. It is established that due to the high number o

Acid-base properties of the Pt-Re catalysts supported on the initial and zirconium-modified alumina were studied. The introduction of 0.1 wt.% ZrO2 into the Pt-Re/Al2O3 catalyst was shown to increase the total concentration of Lewis acid sites (LAS)

Methane adsorption on the Pt–H/Al2O3 and Pt/Al2O3 catalysts begins at Т = 475°C and is accompanied by the appearance of hydrogen in the reaction medium. At a higher temperature is raised to 550°C, the amount of adsorbed hydrogen increases to 1.1

The paper deals with the influence of the methane/platinum on the adsorption properties of aluminic-platinum catalyst. Methane dehydrogenation degree on the Pt/Al 2 O 3 surface has been calculated for the entire range of the studied CH 4 /Pt ratios.

New reforming catalysts PR-81 and SPR-81, which differ from their predecessors (PR-51 and PR-71) in enhanced mechanical strength (1.8–2.0 versus 1.2–1.5 kg/mm), are developed and brought into industrial-scale production by Institute of Problems o

It has been found that the joint aromatization of C4 and C6 alkanes proceeds during the conversion of a butane and hexane mixture on alumina-platinum catalysts. It has been shown that a necessary condition for realization of the joint aromatization i

The texture characteristics of aluminum hydroxides peptized by organic acids and then calcined were studied. A decrease in the pore volume and pore diameter for aluminum hydroxide was studied as a function of the amount of a peptizer. The calcination
