摘要:The invention relates to a process for performing a aqueous synthesis of titanium phosphates (TiP) having solely —H2PO4 groups, which process is characterised by the following steps: providing titanium (IV) oxysulphate, TiOSO4, in an aqueous solution or in a powder and H2SO4, substantially without transition divalent metal ions, including cobalt (II) and copper (II), heating of the thus formed aqueous solution to above 50° C., but below 85° C. for at least 30 minutes, providing a controlled amount of H3PO4 to said aqueous solution, to form an aqueous solution containing a molar ratio between TIO2 and P2Os being controlled to about 1:1, not above 1:1.5 and not below 1:0.7, stirring the thus formed aqueous solution for at least 3 hours to form precipitates of titanium phosphate, and allowing ageing of said solution, without stirring, acidic washing of the formed precipitate using HCI or other acids to obtain TiO(OH)(H2PO4)-H2O having solely —H2PO4 ion-exchange chemical groups and allowing said precipitates to dry to a powder product, substituting protons in the powder product TiO(OH)(H2PO4)-H2O to sodium cations by treatment of the latter with solutions of sodium carbonate and allowing the thus formed powder of Na—TiP1 to dry.

摘要:Provided is a method for manufacturing a catalyst with which it is possible to obtain a supported metal ammonia synthesis catalyst, in which there are restrictions in terms of producing method and producing facility, and particularly large restrictions for industrial-scale producing, in a more simple manner and so that the obtained catalyst has a high activity. This method for manufacturing an ammonia synthesis catalyst includes: a first step for preparing 12CaO·7Al 2 O 3 having a specific surface area of 5 m 2 /g or above; a second step for supporting a ruthenium compound on the 12CaO·7Al 2 O 3 ; and a third step for performing a reduction process on the 12CaO·7Al 2 O 3 supporting the ruthenium compound, obtained in the second step. This invention is characterized in that the reduction process is performed until the average particle diameter of the ruthenium after the reduction process has increased by at least 15% in relation to the average particle diameter of the ruthenium before the reduction process.

摘要:The present disclosure relates to a bifunctional catalyst for manufacturing a hydrocarbon from carbon dioxide and hydrogen. The bifunctional catalyst includes a carbon composite including cobalt (Co) and nitrogen (N) atoms forming a coordinate bond with the cobalt, and metal particles which exhibit a catalytic activity for a Fischer-Tropsch synthesis reaction and which are dispersed on the inner pore surface and/or the outer surface of the carbon composite support, thus simultaneously promoting a reverse water gas shift reaction and the Fischer-Tropsch synthesis reaction.
