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: A method for producing olefins using a circulating fluidized bed process, includes: supplying a propane-containing hydrocarbon mixture and a dehydrogenation catalyst into a riser, which is a fast fluidization regime, to cause a dehydrogenation reaction; separating, from a propylene mixture, the catalyst which is a product of the dehydrogenation reaction; removing unseparated hydrocarbon compounds remaining in the catalyst separated in the separating; continuously regenerating the catalyst by mixing the catalyst stripped in the removing with a gas containing oxygen; circulating the catalyst regenerated in the continuously regenerating to the supplying and resupplying it into the riser; and preparing propylene by cooling, compressing, and separating the propylene mixture which is a reaction product separated in the separating.

Abstract: A hair-penetrating multi-point spraying apparatus for animals with thick fur according to an embodiment of the present invention comprises: a fluid storage part for storing a fluid; a nozzle part provided so as to spray the fluid in close proximity to the skin of an animal with thick fur by means of a plurality of nozzles; and a spraying tool part for supplying the fluid in the fluid storage part to the nozzle part by pumping, The nozzle part has: a plurality of comb teeth for brushing the fur of an animal with thick fur; and a plurality of comb-teeth end nozzles protruding in the form of comb teeth so as to spray a fluid on the skin beneath the fur of the animal with thick fur.

Abstract: The present invention relates to a device and method for producing a sterilizing agent or detergent according to an additive. Specifically, the present invention relates to an electrolysis device including an additive vessel in which an additive to be used for electrolysis is put and a non-membrane electrolytic bath in which the electrolysis is performed, and for the electrolysis, water containing chloride ion (Cl—), sodium chloride (NaCl), and an aqueous hydrochloric acid solution are electrolyzed in a non-membrane electrolytic bath.

Abstract: The present disclosure relates to an apparatus and a method for preparing a disinfectant or a cleaning agent according to an additive. Specifically, the present disclosure relates to an electrolysis apparatus comprising: an additive container to which an additive to be used for electrolysis is added; and a diaphragm-free electrolysis cell in which the electrolysis occurs, wherein, with respect to the electrolysis, water containing chloride ions (Cl?), sodium chloride (NaCl) and a hydrochloric acid (HCl) aqueous solution are electrolyzed in the diaphragm-free electrolysis cell.

Abstract: A beta zeolite catalyst for the preparation of a BTEX (benzene, toluene, ethylbenzene, xylene) mixture from polyaromatic hydrocarbons and a preparation method of the same are disclosed. The beta zeolite catalyst demonstrates high conversion of polyaromatic hydrocarbons and high BTEX production yield by containing optimum contents of the group VIB metals and cocatalysts, so that it can be effectively used as a beta zeolite catalyst for the production of BTEX.

Abstract: The present invention discloses an artificial blood vessel stent, which can minimize the diameter of a stent insertion device because the diameter (profile) thereof is uniform and small over the entire length upon being loaded, and accordingly can be easily placed in a branched portion of a blood vessel using a puncture method.

Abstract: Disclosed are a blood vessel graft and a graft introducer, the graft having a main body and first and second stents each mounted on an end of the main body, the graft introducer including an insertion tube member in which the blood vessel graft main body and the first stent member are inserted in a state where they are contracted, a first pusher member into which the second stent member is inserted in a state where it is contracted, the first pusher member being movably inserted into the insertion tube member to push the first stent member and the blood vessel graft main body out of the insertion tube member, and a second pusher member in which a catheter passing through the introducer is inserted, the second pusher member being movably inserted into the pusher member to push the second stent member inserted in the first pusher member out of the insertion tube member, thereby disposing the blood vessel graft in the blood vessel.
