    Abstract: The invention relates to jet fuel compositions, in particular jet fuel compositions having improved cold properties, and more particularly improved freezing point with respect to theoretical linear behavior, which are mixtures of jet fuel from petroleum origin and renewable component. To this effect, a jet fuel composition comprising a petroleum derived jet fuel component and a renewable component consisting of hydroprocessed esters and fatty acids is proposed, wherein the jet fuel composition contains 1 to 50 vol % of the renewable component and has a freezing point of −40° C. or below, preferably of −47° C. and below, and the petroleum derived jet fuel component has a content of C9-C12 normal paraffins from 17 wt % to 30 wt %.

    Abstract: A method for treating a waste plastic based on a persulfate system is provided. The method includes the following steps: mixing the waste plastic, sulfuric acid, sulfate, peroxymonosulfate, and water, and reacting at 80-140° C. for 3-15 h to complete the treatment; where the waste plastic is polyethylene or polyethylene terephthalate; and the sulfate is copper sulfate or ferrous sulfate. The present invention reasonably regulates and controls each parameter in the reaction process while constructing a homogeneous catalysis system of transition metal activated peroxymonosulfate, and finally directionally converts the waste plastic into C7H12 and C10H12 fuels, which realizes high-efficiency recycling of the waste plastic, has a simple and convenient working procedure, and has a wide application prospect.
