    • This invention provides methods for producing ethylene glycol from polyhydroxy compounds such as cellulose, starch, hemicellulose, glucose, sucrose, fructose, fructan, xylose and soluble xylooligosaccharides. The methods uses polyhydroxy compounds as the reactant, a composite catalyst having active components comprising one or more transition metals of Groups 8, 9, or 10, including iron, cobalt, nickel, ruthenium, rhodium, palladium, iridium, and platinum, as well as tungsten oxide, tungsten sulfide, tungsten hydroxide, tungsten chloride, tungsten bronze oxide, tungsten acid, tungstate, metatungstate acid, metatungstate, paratungstate acid, paratungstate, peroxotungstic acid, pertungstate, heteropoly acid containing tungsten. Reacting at a temperature of 120-300° C. and a hydrogen pressure of 1-13 MPa under hydrothermal conditions to accomplish one-step catalytic conversion. It realizes efficient, highly selective, high yield preparation of ethylene glycol and propylene glycol from polyhydroxy compounds. The advantage of processes disclosed in this invention include renewable raw material and high atom economy. At the same time, compared with other technologies that converts biomass raw materials into polyols, methods disclosed herein enjoy advantages including simple reaction process, high yield of targeted products, as well as easy preparation and low cost for the catalysts.
    • 本发明提供从多羟基化合物如纤维素,淀粉,半纤维素,葡萄糖,蔗糖,果糖,果聚糖,木糖和可溶性低聚木糖中生产乙二醇的方法。 该方法使用多羟基化合物作为反应物,具有包含一种或多种第8,9或10族过渡金属(包括铁,钴,镍,钌,铑,钯,铱和铂)的活性组分的复合催化剂,以及 作为氧化钨,硫化钨,氢氧化钨,氯化钨,青铜氧化钨,钨酸,钨酸盐,偏钨酸,偏钨酸盐,仲钨酸,仲钨酸盐,过钨酸,过钨酸盐,含钨杂多酸。 在水热条件下,在120-300℃的温度和1-13MPa的氢压下进行反应,完成一步催化转化。 它实现了从多羟基化合物的乙二醇和丙二醇的高效,高选择性,高产率的制备。 本发明公开的方法的优点包括可再生原料和高原子经济性。 同时,与将生物质原料转化为多元醇的其他技术相比,本文公开的方法具有包括简单的反应过程,高产率的目标产物以及易于制备和低成本的优点。
