Abstract: The present invention relates to a catalyst for converting diesel and kerosene, which are increasingly likely to be not utilized, into basic chemical raw materials, and a method for producing the catalyst, and the catalyst is a catalyst containing a porous zeolite having pores; and phosphorus (P) supported in internal pores of the zeolite and on a surface of the zeolite, wherein the amount of Lewis acid sites in the phosphorus-supported zeolite is 20 to 100 ?mol/g, and the catalyst is used for producing a basic chemical raw material through catalytic cracking of a hydrocarbon feed having a boiling point of 150° C. or higher and 550° C. or lower.

Abstract: The present invention relates to a method for manufacturing a paper buffer tray for packaging and a buffer tray manufactured thereby, wherein a plurality of papers are laminated and processed such that some papers are cut in a length direction, wrinkles or the like are formed in the other papers, and press-molding is performed using a mold, thereby providing an eco-friendly buffer tray and overcoming a disadvantage in that it is difficult to mold a buffer tray by using an existing paper. The method for manufacturing the paper buffer tray for packaging includes: a raw material preparing step of preparing a raw material for manufacturing a buffer tray in which a plurality of papers are laminated; a molding preparing step of preparing at least one mold corresponding to a shape and size of a product to be packaged; and a molding step of press-molding the raw material by using the at least one mold.

Abstract: Provided is an underground environment change detection method including: repeatedly sensing an AC signal propagated through an underground in a magnetic induction manner; and monitoring an underground environment change from a change in the AC signal.

Abstract: An image display device and a control method therefor are disclosed. The image display device manages the positions of objects by dividing its display screen into grids. Thus, overlap between objects is efficiently prevented and unnecessary computations for avoiding the overlap are relieved from a controller. Also, the displayed area of an object may be shifted in various patterns.
