Description

Vulcanized Rubber Thermal Decomposition Apparatus and Method The present invention relates to a vulcanized rubber pyrolysis apparatus and method. Compared to other treatment methods for solid waste, pyrolysis can reduce secondary pollution while simultaneously yielding economically valuable pyrolysis gas, oil, and charcoal. Among these, pyrolysis oil is a high-value resource that can be recycled into fuel oil, boiler oil, and petrochemical products, and research on technologies for manufacturing and refining it is actively underway. However, in the case of tires, the rubber is given a unique elasticity through a vulcanization reaction during the manufacturing process. For this reason, waste tire oil obtained by pyrolyzing waste tires has a high sulfur content, and in order to increase its usability as fuel and petrochemical products, the sulfur must be reduced. In conventional pyrolysis equipment, a hydrodesulfurization process is carried out by reacting cooled pyrolysis oil with hydrogen to remove sulfur compounds. This process requires mixing the substance to be desulfurized with hydrogen, preheating the mixture, reacting it under a catalyst, and introducing a device to separately capture the hydrogen. Consequently, this results in high initial investment costs for additional process equipment and has the disadvantage of reduced efficiency.

FIG. 2 is a flowchart briefly illustrating the process of a vulcanized rubber pyrolysis apparatus according to one embodiment of the present invention. The above objects, other objects, features, and advantages of the present invention will be easily understood through the following preferred embodiments associated with the accompanying drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided to ensure that the disclosed content is thorough and complete and to ensure that the spirit of the invention is sufficiently conveyed to a person skilled in the art. In describing each drawing, similar reference numerals have been used for similar components. In the attached drawings, the dimensions of the structures are depicted enlarged from their actual size for clarity of the invention. Terms such as "first," "second," etc., may be used to describe various components, but said components should not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the invention, the first component may be named the second component, and similarly, the second component may be named the first component. A singular expression includes a plural expression unless the context clearly indicates otherwise. In this specification, terms such as "comprising" or "having" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Furthermore, when a part such as a layer, film, region, or plate is described as being "on" another part, this includes not only the case where it is "immediately above" the other part, but also the case where there is another part in between. Conversely, when a part such as a layer, film, region, or plate is described as being "below" another part, this includes not only the case where it is "immediately below" the other part, but also the case where there is another part in between. Unless otherwise specified, all numbers, values, and/or expressions used herein to represent amounts of ingredients, reaction conditions, polymer compositions, and formulations should be understood to be modified by the term “approximately” in all cases, as these numbers are essentially approximations reflecting the various uncertainties of measurement that occur in obtaining these values among other things.
