    • Disclosed is a process for producing light olefins from hydrocarbon feedstock. The process is characterized in that a porous molecular sieve catalyst consisting of a product obtained by evaporating water from a raw material mixture comprising a molecular sieve with a framework of Si—OH—Al— groups, a water-insoluble metal salt, and a phosphate compound, is used to produce light olefins, particularly ethylene and propylene, from hydrocarbon, while maintaining excellent selectivity to light olefins. According to the process, by the use of a specific catalyst with hydrothermal stability, light olefins can be selectively produced in high yield with high selectivity from hydrocarbon feedstock, particularly full-range naphtha. In particular, the process can maintain higher cracking activity than the reaction temperature required in the prior thermal cracking process for the production of light olefins, and thus, can produce light olefins with high selectivity and conversion from hydrocarbon feedstock.
    • 公开了一种从烃原料生产轻质烯烃的方法。 该方法的特征在于,由通过从包含具有Si-OH-Al-基团的骨架的分子筛,水不溶性金属盐和磷酸盐的原料混合物蒸发水而获得的产物的多孔分子筛催化剂 化合物,用于从烃生产轻质烯烃,特别是乙烯和丙烯,同时保持对轻质烯烃的优异选择性。 根据该方法,通过使用具有水热稳定性的特定催化剂,可以从烃原料,特别是全范围石脑油以高选择性高选择性地制备轻质烯烃。 特别地,该方法可以保持比用于生产轻质烯烃的现有热裂解方法中所需的反应温度更高的裂化活性,因此可以从烃原料生产具有高选择性和转化率的轻质烯烃。
