摘要： A porous preform (carrier) is soaked in an impregnating solution, which contains both of a catalytic-activity constituent, e.g. Ni and/or Co, and a carrier-forming constituent, e.g. Mg, Al, Zr, Ti and/or Ca, so as to simultaneously infiltrate the catalytic-activity and carrier-forming constituents into the porous preform. The impregnated preform is dried, calcined at a temperature of 700° C. or higher and then activated at a temperature of 500° C. or higher, whereby fine catalytic-activity particles are distributed on a surface of the porous carrier with high dispersion. Due to finely-distributed catalytic-activity particles, the surface of the catalyst is prevented from deposition of carbonaceous matters during reformation of hydrocarbon and held in an active state over a long term.

摘要： A multilayer sliding member is provided that contains no lead but has superior friction and abrasion properties under the conditions of high PV values and can be used suitably in dry lubrication environments. The multilayer sliding member includes: a porous metal layer that is formed on a back metal; and a sliding layer that is formed by impregnating and coating the porous metal layer, wherein the sliding layer includes 1 to 25% by volume of an oxybenzoyl polyester resin, 1 to 15% by volume of a phosphate, 1 to 20% by volume of barium sulfate, and polytetrafluoroethylene resin. The oxybenzoyl polyester resin (POB) improves the strength and abrasion resistance of the sliding material, and the synergistic effect of the phosphate and barium sulfate facilitates the transfer of PTFE to a counter material during sliding, so that the coefficient of friction can be decreased and the abrasion resistance can be improved.
