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 aim of this study was to obtain new catalysts for the processing of carbon-containing polymer waste based on polyethylene and polypropylene, represented mostly by lids from beverages bottled in plastic containers, which accumulate in huge quantities i... see more

Two steps transformation of (+)-citronellal, cyclization and hydrogenation, on ZnBr2/?-Al2O3 and Ni/?-Al2O3 catalyst have been realized with the selectivity to cyclization products (isopulegols) was very high (yield up to ~92.58%) over ZnBr2/?-Al2O3 under... see more

Catalytic hydrogenation of eugenol (Mr 164) and isoeugenol (Mr 164) by using synthetic catalyst Ni/?-Al2O3 had been carried out. Eugenol transformation into 2-methoxy-4-propylphenol (Mr 166) as a main product could be achieved in 100% and no conversion re... see more

The research on the preparation of nickel catalyst impregnated on active carbon by two methods has been carried out. The impregnation of Ni metal was done using nickel(II) chloride as a precursor. The impregnated of Ni metal on samples in A method was mad... see more

Hydrogenated liquid natural rubber (HLNR) was synthesized from liquid natural rubber (LNR) by thermolysis of p-toluenesulfonyl hydrazide (TSH). The HLNR structure was characterized by Fourier-transform infrared (FTIR) and nuclear magnetic resonance (NMR) ... see more

Selective hydrogenation of sugars (e.g. sucrose, cellobiose, glucose, fructose, xylose, arabinose) into sugar alcohols (sorbitol, mannitol, xylitol, arabitol) can be achieved by means of supported Raney Ni-based catalysts. Various supporting materials suc... see more

Inexpensive Raney Ni-clay composite (R-Ni/clay) catalysts exhibited excellent activity and reusability in the total hydrogenation of biomass-derived furfural into tetrahydrofurfuryl alcohol under mild conditions. For the Raney Ni-bentonite (R-Ni/BNT) cata... see more

The catalytic activities of Cu/ZrO2_CaO catalysts were investigated on CO2 hydrogenation. The CO2 hydrogenations were carried out over combination of calcium oxide and Cu/ZrO2 catalyst. Two calcination temperatures were chosen at 300 and 650oC according t... see more
