Abstract: An integrator for global elastic motion mode of human body comprises an elastomer (1A,1B) and at least five joint fixing elements (2) worn on the joint parts of the human body. Initial points (4) of the elastomer (1A,1B) are fixed on two joint fixing elements (2), and end points (5) are fixed on three joint fixing elements (2). Location buckles (3) allowing the elastomer (1A,1B) to pass through are provided on the intermediate joint fixing elements (2) except the joint fixing elements (2) on the initial points (4) and the end points (5). The integrator for global elastic motion mode of the human body overcomes the shortcoming that exercise apparatus and exercise protective equipment in the prior art lack the ability of integration and protection. The efficiency and security of training are improved.

Abstract: A catalyst and process is described for the conversion of hydrogen and one or more oxides of carbon in which the catalyst comprises an elemental carbon-containing support. Also described is a process for reducing agglomeration in carbon nanotubes, in which carbon nanotubes are suspended in a liquid and simultaneously treated by ultrasound and agitation. The method can be used to prepare carbon nanotube-supported catalysts that show high activity towards the conversion of feedstocks comprising hydrogen and one or more oxides of carbon.

Abstract: A catalyst is invented for the synthesis of C2-oxygenates by the hydrogenation of CO. The catalyst is composed of Rh—Mn—Fe-M1-M2/SiO2, among them Mn, Fe, M1 and M2 and additives. M1 can be Li or Na while M2 can be Ru or Ir. The content of Rh is 0.1-3% by weight; the weight ratio of Mn/Rh is 0.5-12, the weight ratio of Fe/Rh is 0.01-0.5, the weight ratio of M1/Rh is 0.01-1 and the weight ratio of M2/Rh is 0.1-1.0. The catalyst is prepared by impregnation of the solution of corresponding compounds of each component in desired amount onto the carrier of SiO2, which is followed by drying at 283-473 K. Before using, the catalyst is reduced by hydrogen or hydrogen-containing gas at 573-673 K for at least one hour after drying or after calcinations at 473-673 K for 2-20 h. These catalysts can convert CO and H2 into ethanol, acetaldehyde, acetic acid and other C2-oxygenates at a high conversion and a high selectivity under mild conditions.

Abstract: A synthesis of the micro-porous silica gel and its application to preparation of catalysts for C2 oxygenates synthesis from syngas is invented. The small particles of silica gel which are, produced by sol gel process are heated in a basic solution, followed by drying and/or calcinations, and thus form micro-porous silica as catalyst support. The basic solution can be one or a mixed solution of hydroxides, carbonates, bicarbonates, formates and acetates of alkali metal and ammonium. The obtained micro-porous silica can be impregnated with the solutions of rhodium salt and other transition element salts (as promoter precursors), followed by drying and/or calcinations, thus forming a micro-porous silica supported rhodium based catalyst. The rhodium salt can be RhCl3 or Rh(NO3)3. The promoter precursors can be water-dissolvable transition metal salts, rare earth metals salts, alkali metal salts and alkali earth metal salts.
