摘要:
The present disclosure relates to providing a positioning service by managing a plurality of peripheral wireless LAN signals. The positioning service system collects peripheral wireless LAN radio signals by scanning peripheral access points (APs), stores AP information of each of peripheral wireless LAN radio signals in each lattice cell of a database. When a positioning request signal is received from a terminal, a positioning server of the positioning service extracts AP identification information from included in the peripheral wireless LAN radio signal received from the terminal. By using the extracted AP identification information, the positioning server selects from the database the corresponding lattice cell matching to the stored AP identification information of each of the peripheral wireless LAN radio signals pre-stored. And the positioning server estimates location information of the selected corresponding lattice cell as location information for the terminal.
摘要:
The present disclosure provides a system, device and method for estimating an AP location using log data. Information, which is not pre-stored in a database when the information is updated, is classified and then location information of an AP is estimated by using log data of a user in such a manner of estimating a location of the AP by using log data of a user in wireless LAN based positioning and thus updating the database for the wireless LAN based positioning, thereby improving positioning accuracy.

Disclosed is a catalytic cracking process for the production of light olefins from a hydrocarbon feedstock using fast fluidization, which is a preferred process for more efficiently increasing the production of light olefin hydrocarbons. According to this invention, a fast fluidization regime is applied to a fluidized bed catalytic cracking process of producing light olefins using zeolite, such that a volume fraction and distribution of the catalyst sufficient to induce the catalytic cracking reaction can be provided, thus effectively enhancing the production of light olefin hydrocarbons, in particular, ethylene and propylene, at high selectivity.
摘要:
Disclosed are a molecular sieve catalyst and a preparation method thereof to produce light olefins from cracking naphtha catalytically in severe environments of high temperature and high moisture. In detail, the catalyst is prepared by spray-drying and calcining the mixed slurry, in which 0.01˜5.0 wt % of MnO2 and 1˜15 wt % of P2O5 are simultaneously imbedded in catalyst which consists of zeolite, clay and inorganic complex. According to the present invention, the method that manganese and phosphate are imbedded simultaneously in zeolite and inorganic complex is used to increases thermal-stability of obtained spherical catalyst, and increase olefin yield of cracking hydrocarbon such as naphtha by protecting acid-site of zeolite. To synthesize the required catalyst, the important procedures are mixing ratio and mixing sequence of Mn, P, zeolite, and inorganic complex.
