the synthesis of u043cu0438u043au0440u043eu043fu043eu0440u0438u0441u0442u043eu0433u043e u0441u0438u043bu0438u043au0430u0433u0435u043bu044f and its application for the preparation of catalysts for the synthesis of - u043eu043au0441u0438u0433u0435u043du0430u0442u043eu0432 from synthesis gas.small particles of u0441u0438u043bu0438u043au0430u0433u0435u043bu044f receiving sool, switzerland - gel method, heated in the main solution, then dried and / or u043fu0440u043eu043au0430u043bu0438u0432u0430u044eu0442,and thus formed u043cu0438u043au0440u043eu043fu043eu0440u0438u0441u0442u044bu0439 silicon dioxide for use as a carrier for catalysts.the solution may be a solution of a salt or a mixed solution of u0433u0438u0434u0440u043eu043au0441u0438u0434u043eu0432, carbonates, u0431u0438u043au0430u0440u0431u043eu043du0430u0442u043eu0432, u0444u043eu0440u043cu0438u0430u0442u043eu0432 and u0430u0446u0435u0442u0430u0442u043eu0432 alkali meth alla and ammonium.the u043cu0438u043au0440u043eu043fu043eu0440u0438u0441u0442u044bu0439 silicon dioxide can soak solutions rhodium salt and salts of other transition elements (promoter or as before), and u0437u0430u0442u0435 m dry and / or u043fu0440u043eu043au0430u043bu0438u0442u044c,thus it u043cu0438u043au0440u043eu043fu043eu0440u0438u0441u0442u044bu0439 caused by silicon dioxide catalyst based on rhodium. rhodium salt may represent a RhClu0438u043bu0438 rh (no).predecessors promoter or may constitute a water soluble transition metal salt, salt of rare earth metals, salt, alkali metal salt and u0449u0435u043bu043e why worry then - a land of metal.the catalysts show high activity and selectivity in the synthesis of c - u043eu043au0441u0438u0433u0435u043du0430u0442u043eu0432 u0433u0438u0434u0440u0438u0440u043eu0432u0430u043du0438u0435u043c with with soft reaction conditions.
