This paper presents the results of a study on the catalytic activity and selectivity of nickel and palladium catalysts in hydrogenation reactions of nitro- and acetylene compounds. It was shown that the activity and selectivity of nickel catalysts in the ... see more

The paper considers the diatomite-supported platinum catalyst (1.0 wt% Pt/D) synthesized using colloid adsorption method. The catalyst was characterized by X-ray diffraction, N2 adsorption (BET), scanning electron microscopy and transmission electron micr... see more

Influence of dispersion of oxides V2O5, TiO2, ZrO2 on durability of V-Ti-Zr of catalysts is studied. It is shown that the disperse structure of initial components of V-Ti-Zr-oxide catalysts defines dispersion of the ready catalyst that influences its cata... see more

The iminodiacetic acid-modified Nieuwland catalyst not only improves the conversion of acetylene but also increases the selectivity of monovinylacetylene (MVA). A catalyst system containing 4.5% iminodiacetic acid exhibited excellent performance, and the ... see more

Research on the synthesis of mesoporous silica catalyst, as well as its activity and selectivity in the hydrocracking of used palm oil, has been carried out. The research involved the preparation of mesoporous silica catalyst by varying the volume ratio o... see more

Fischer-Tropsch Synthesis (FTS) using Fe-Co/meso-HZSM-5 catalyst has been investigated. The impregnated iron and cobalt on HZSM-5 could be used as bifunction catalyst which combined polimerizing synthesis gas and long hydrocarbon cracking for making biofu... see more

Mesoporous silica (MS) supported by nickel was synthesized from Parangtritis beach sand and assessed for its activity and selectivity as catalysts in hydrocracking waste cooking oil into biofuel. The synthesis of MS was done by the sol-gel method. Ni/MS c... see more

 In the present work, the synthesis of Co/SBA-15 catalysts intended for Fischer-Tropsch (FT) synthesis was performed. During the synthesis of catalysts there was contamination of samples with sodium nitrate due to the nature of the reducing agent use... see more

Since most chemical processes are catalytic; the problem of the choice of catalysts is traditionally considered in many publications and is covered on many Internet sites. In this paper; the catalytic process of methane oxidative condensation and intellig... see more
