Abstract: Provided is an approach for scaling up a multiphase plasma chemical reactor that uses gas bubble discharge in liquids. One example involves single spark gap discharge scale up systems and processes with suitable characteristic parameters. Scaling parameters are based on the size change of one spark gap. Another example involves scale-up systems and processes that can be applied to multiple spark gaps with multiple discharge modules and its dimension information. Numbers of modules and resulting device sizes could be based on required production rate and specific energy input. Applications allow for scaling up of any plasma chemical system or process with similar mechanisms and reactors, such oil treatment reactors.

Abstract: A temperature-controlling measure for a hydrogenation slurry bed reactor has three control points that are set from low to high: cold hydrogen is injected automatically when the system reaches control point 1; cold oil is injected automatically when the system reaches control point 2; each pressure relief is opened automatically when the system reaches control point 3. The pressure relief point is set before and/or after the circulation pump of the reactor if internal circulation is set in the reactor; the pressure relief point is set at the reactor bottom if the internal circulation is not set; at least one pressure relief valve is set at each pressure relief point.

Abstract: Disclosed are a WIFI networking method and system via infrared transmission. The WIFI networking method comprises: in a WIFI networking mode, a terminal acquires networking information about a router and converts same into an infrared signal and transmits the infrared signal to an electrical appliance; the electrical appliance receives and parses the infrared signal to obtain the networking information, and initiates a connection request to the router according to the networking information; and the electrical appliance establishes a WIFI connection to the router in response to the connection information about the router. By means of transmission in an infrared manner, even in a complicated WIFI environment, a quick and stable WIFI connection can be realized without the electrical appliance monitoring all the time, thereby reducing the power consumption. The present invention also makes use of the existing infrared transceiving modules in the terminal and the electrical appliance, thereby saving costs.
