Abstract: A button lighting module is provided including: a light guide plate which has a button through-hole formed in a thickness direction to allow a button device configured to input a command to pass therethrough and has a light refractor provided around the button through-hole to refract a light path upward; and a light source which is configured to radiate light so that the light is incident on the light guide plate through an outer peripheral side surface of the light guide plate.

Abstract: The present invention relates to a method and system for the continuous preparation of gasoline, kerosene, and diesel oil from waste plastics. The method comprises the steps of: subjecting a melt of the waste plastics to a first catalytic reaction in which the waste plastic melt is in contact with a nickel or nickel alloy catalyst to be dehydrogenated while being decomposed; subjecting the dehydrogenated and decomposed waste plastic melt to a fluid catalytic cracking, as a second catalytic reaction to produce a gasoline-based fraction at a high fraction; fractionating the cracked material into a gasoline-based fraction, a kerosene fraction, and a diesel oil fraction; and reforming the gasoline-based fraction to produce a high octane number gasoline. The present invention can apply to a small scale facility, not to apply to a large scale facility.
