    摘要： he process for preparing a high-octane gasoline involves catalyzing a light hydrocarbon containing one or more C 2 -C 7 paraffins and/or C 2 -C 7 olefins with a crystalline aluminogallosilicate with the skeleton comprised of SiO 4 , AlO 4 and GaO 4 tetrahedra at temperatures ranging from 350°C to 650°C under a hydrogen partial pressure of not higher than 5 kg/cm 2 . The crystalline aluminogallosilicate to be used as the catalyst for the process has its skeleton comprised of SiO 4 , AlO 4 and Ga0 4 tetrahedra and having the following formula:
    wherein M is a metal selected from an alkaline metal, and alkaline earth metal and a mixture thereof, n is the valence of said metal, a is a positive number of (b + 1) ± 3.0, b is between 0.3 and 30, c is between 8 and 2,000, and d is between 1 and 200.

    摘要： Aromatic hydrocarbons are produced by catalytic conversion of aliphatic hydrocarbons using an aluminogallosilicate catalyst. A feed of the aliphatic hydrocarbon is mixed with a recycle gas and the mixture is contacted with the catalyst. The resultant conversion product is separated into a gas phase and a liquid phase containing aromatic hydrocarbons. The gas phase is separated into a hydrogen-rich gas and a methane- and/or ethane-rich gas while the liquid phase is separated into an aromatic hydrocarbon-containing product and a light hydrocarbon-containing gas. At least part of the methane- and/or ethane-rich gas and the light hydrocarbon-containing gas is recycled as the above recycle gas. The catalytic conversion is performed while increasing the reaction temperature as the process proceeds.

    摘要： A process for preparing pyruvate in high yield is disclosed, comprising reacting propylene glycol with molecular oxygen in an aqueous solution in the presence of a platinum catalyst containing a metallic component selected from the group consisting of lead, thallium, and cadmium while controlling the pH of the reaction mixture between 7 and 9. The crude pyruvate can be purified by treating with activated carbon in the presence of water.
