The present invention relates to an apparatus and a method for treating ballast water, and an exemplary embodiment of the present invention provides a ballast water treatment apparatus including: a tank; a spray nozzle which supplies ballast water in the form of droplets into the tank; and a gas circulation unit which supplies inert gas to the spray nozzle, and sucks inert gas that is not dissolved in the ballast water in the tank.

Apparatus and method for treating ballast water

A method of reforming a heavy hydrocarbon distillate, which includes treating a heavy hydrocarbon distillate and a lignocellulosic biomass with a solvent, is provided. The method can be useful in maximizing conversion of the heavy hydrocarbon distillate into higher value-added distillate, for example, naphtha and a middle distillate, and allowing a sulfur compound produced by the decomposition of a heavy hydrocarbon distillate to catalyze pretreatment of the lignocellulosic biomass. Also, oxygen, hydroxymethylfurfural (HMF), levulinic acid, formic acid, and sulfuric acid produced by decomposition of the lignocellulosic biomass can catalyze decomposition of a heavy hydrocarbon distillate and lignocellulosic biomass, thereby activating decomposition of a heavy hydrocarbon distillate.

The present invention relates to a method of preparing a hollow carbon structure. The method includes a step of calcining a solid component separated after a cracking reaction of a heavy hydrocarbon fraction; and a step of performing an acid treatment or base treatment on the solid component calcined in the above-described step. The present invention provides a method of preparing a hollow carbon structure which may be used to separate carbon dioxide, to remove a sulfur compound, and as a carrier of various substances by performing various pre-processes on carbon generated on a surface of a spent catalyst which is used in a cracking reaction of a heavy hydrocarbon fraction.
