    摘要： Processes are disclosed for the conversion of a carbohydrate source to hexamethylenediamine (HMDA) and to intermediates useful for the production of hexamethylenediamine and other industrial chemicals. HMDA is produced by direct reduction of a furfural substrate to 1,6-hexanediol in the presence of hydrogen and a heterogeneous reduction catalyst comprising Pt or by indirect reduction of a furfural substrate to 1,6-hexanediol wherein 1,2,6-hexanetriol is produced by reduction of the furfural substrate in the presence of hydrogen and a catalyst comprising Pt and 1,2,6-hexanediol is then converted by hydrogenation in the presence of a catalyst comprising Pt to 1,6 hexanediol, each process then proceeding to the production of HMDA by known routes, such as amination of the 1,6 hexanediol. Catalysts useful for the direct and indirect production of 1,6-hexanediol are also disclosed.

    摘要： A catalytic process and a nano material for the conversion of moist carbon dioxide into methanol, propyne and oxygen have been developed. In the process invented, hydrogen is produced from water in a catalytic reaction, when the moist carbon dioxide enters into the catalytic reactor, resulting in C—O and H—OH bond breakage at a relatively low temperature and at atmospheric pressure in a single step using a combination of catalytic materials comprising at least three metals dispersed on a catalyst support, preferably anatase form of titanium dioxide, to induce a multifunctional surface chemical reaction for the production of oxygenated products such as hydrocarbons of different chain lengths.
