New routes for dissociation of ethylene complexes of platinum(II): reduction and hydrohalogenation of ethylene in aqueous acid solutions

J. Gen. Chem. USSR (Engl. Transl.); (United States) (1988)

At 353 K in 2.5 M NaI solution with (HClO/sub 4/) = 2.5 M and (Pt(II)) = 0.1 M (initial complex K/sub 2/PtCl/sub 4/ or KPtCl/sub 3/(C/sub 2/H/sub 4/)) ethylene gave a 1.5:1 mixture of ethane and ethyl iodide with a first-order rate constant of k = 2.35/centered dot/10/sup /minus/2/ sec/sup /minus/1/. Under those conditions, the half-life for conversion of ethyl iodide to ethane and ethylene was several hours. At a steady ionic strength ((NaI) + (HClO/sub 4/) = 5.0 M) k increased with increase in concentration of platinum (II), I/sup minus/, and H/sup +/. An increased yield of ethane was also obtained with higher H/sup +/ and Pt(II) concentrations. The reaction products were identified, and the yields were determined by GLC.

BIFUNCTIONAL СО/SIO2-Fe-ZSM-5-Al2O3 CATALYSTS FOR SYNTHESIS OF HYDROCARBONS OF ENGINE FRACTIONS

The process of obtaining motor fractions of hydrocarbons on bifunctional Со/SiO2-Fe-ZSM-5-Al2O3, catalysts obtained by mixing has been studied. The effect of the method of introducing iron into a catalyst (in the form of reduced iron and its nitrate) at the molding stage is studied. The catalysts were tested in a continuous mode for 30 h at a gas volume velocity of 1000 h-1, a pressure of 2 MPa and a temperature of 240 ° C. It is shown that when iron is introduced in the form of a reduced powder, the temperature gradient in the catalyst bed decreases, and the selectivity for C5+ hydrocarbons increases by 6% in comparison with the catalyst sample without the addition of iron. It has been established that the introduction of iron into the catalyst in the form of a nitrate salt is a less effective method. It blocks the operation of polymerization and acid sites of bifunctional catalysts, contributes to a reduction in CO conversion and selectivity for C5+ hydrocarbons. It is shown that the introduction of iron significantly changes the group composition and molecular-mass distribution of the produced hydrocarbons - the shares of saturated hydrocarbons are increases, predominantly of a linear structure, the yield of olefins decreases. The obtained C5+ hydrocarbons mainly consist of gasoline and diesel fractions. The introduction of iron promotes an increase in the content of diesel fractions in synthesis products. Thus, with the introduction of iron in the form of a nitrate salt, the content of the diesel fraction increased by 1.2 times in comparison with the sample of a catalyst without iron.

Разложение аммиака на Co-Al2O3 /SiO2 катализаторах: влияние способов восстановления кобальта

The focus on "green" energy requires the search for environmentally friendly energy storage systems. The reason for choosing ammonia as a potential storage for hydrogen is its high energy capacity and the absence of carbon and nitrogen oxide emissions during decomposition. Herein, we tested Co-Al 2 O 3 /SiO 2 ammonia decomposition catalysts that had been pre-activated via cyclic hydrogenation-carburization-hydrogenation (RCR) and reduction-oxidation-reduction (ROR) procedures versus the conventional cobalt oxides reduction with hydrogen (R). The samples were characterized by H 2 -TPR, TEM and synchrotron X-ray diffraction techniques, which revealed that the structural properties of the catalysts were not modified by the reaction. Since the activities of the tested catalysts and the effective reaction barriers appeared to be close, the easiest-to-prepare catalyst R was chosen for the long-term catalytic trial (500 h), and it showed excellent performance stability.
