TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The catalyst composition comprises Pr0.8Sr0.2Cr0.95Ru0.05O3; Gd0.8Sr0.2Cr0.95Ru0.05O3; La0.9Ce0.1Cr0.95Ru0.05O3; La0.8Sr0.2Cr0.95Ru0.05O3; La0.8Sr0.2Cr0.9Ni0.10O3; La0.8Sr0.2CrO3; La0.8Sr0.2Al0.95Ru0.05O3; La0.8Sr0.2Cr0.95Ru0.50O3; LaAl0.95Ru0.05O3; or LaCr0.95Ru0.05O3. Preferred Method: The method includes calcinating the catalyst at 800degreesC for 1 hour. Preferred Definitions:    A (for (I) and (II)) = La, Y, and/or preferably Pr and/or Gd, or Sr;    A' = Ca, Sr, Ba, and/or Ce;    B = Ni, Cu, Zn, Ga, Al, Cr, Ti, V, Mo, W, Zr, Nb, and/or Sn;    B' = Ru, and/or Rh;    x (for (I) and (II)) = 0-0.5, preferably 0.1-0.2;    y (for (I) and (II)) = 0-0.2, preferably 0.05;    z = 0-0.2.    EXAMPLE - A LaCr0.95Ru0.05O3 catalyst was prepared by dissolving lanthanum nitrate-containing compound (La(NO3)3.6H2O) (17.9 g), chromium nitrate-containing compound (Cr(NO3)3.9H2O) (15.8), ruthenium nitrate-containing compound (Ru(NO)(NO3)3) (0.66 g), and glycine (12 g) with deionized water in quartz beaker. The mixture was evaporated over hot-plate, and ignited to obtain LaCr0.95Ru0.05O3 powder. The powder was placed in ceramic dish and calcined at 800degreesC in dry air for 1 hour. The powder was pressed and palletized to 20/40 mesh size catalyst pellet. A catalyst sample (0.9 g) was packed into reactor zone of the diesel reforming micro-reactor. The catalyst was first mixed with low surface alpha-alumina ceramic chips before loaded to the reactor. During catalytic reaction, the surrounding heater for the catalyst bed was set at 725degreesC. Mixture of air, steam and fuel was fed at 2.75x10-3 g-fuel/g-catalyst sec. High purity dodecene (greater than 98%) was used as surrogate fuel. The hydrogen rich reformate generated from the reactor was analyzed. Results showed that the catalyst had hydrogen (H2) yield of 22.6 mold-H2/mol-fuel, reforming efficiency of 80%, and carbon oxides (COx) selectivity of 98.5% at the condition of O2/C=0.5 and H2O/C=3; and H2 yield of 20.3 mold-H2/mol-fuel, reforming efficiency of 87.1%, and COx selectivity of 98% at the condition of O2/C=0.42 and H2O/C=1.
