    摘要: 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.

    摘要: Disclosed herein is a dome security camera. The camera includes a housing having a circuit part. A hemispherical cover is coupled to the housing. A camera module includes a casing which has a lens mounted on a central portion thereof and coupled to a barrel, a plurality of LEDs, and a sensor. A bracket is provided in the housing and coupled to the casing in such a way that it is rotated and open or closed. The casing has a hemispherical shape, and an annular coupling step is provided on a lower end of the casing. The bracket is a cylindrical member having an opening on an upper end thereof, and includes an enlarged part provided on the upper end of the opening and coupled to the casing, and a cut groove formed by cutting a side surface of the bracket, with a knob inserted into the cut groove.
