Provided is a technology of converting an oil having a high content of Cl into a solvent. Impurities such as Cl, S, N, and metals are removed from an oil having a boiling point of 180 to 340° C. in a waste oil having a high content of Cl, and hydroisomerization is carried out, thereby applying an oil having a high isoparaffin ratio as a solvent. After a separation by boiling points according to the properties of the solvent product, a solid acid material and an oil having a high Cl content are mixed, impurities are removed by a heat treatment at a high temperature, and hydroisomerization is carried out by a noble metal/1-D zeolite catalyst, thereby, manufacturing a solvent product.

Solvent composition prepared from waste oil and method of preparing the same

Disclosed is a process for converting methane into value-added compounds. In this process, a gas mixture containing hydrogen as well as high-concentration acetylene formed through methane pyrolysis (e.g. non-oxidative coupling of methane) is selectively hydrogenated in the presence of a bimetallic supported catalyst. This process obtains ethylene from acetylene in the gas mixture while unreacted methane and hydrogen are recovered as byproducts and/or additionally recycled.

Process of selectively hydrogenating gas mixture having high acetylene content

Provided is a technology to convert an oil having a high content of Cl into a solvent. Impurities such as Cl, S, N, and metals are removed from an oil having a boiling point of 340&#xb0; C. or lower in a waste oil having a high content of Cl, and hydrogenation is carried out to recover an oil, and the oil may be applied as a solvent. Separation by boiling points to meet the properties of the solvent product is performed, a solid acid material and an oil having a high Cl content are mixed, impurities are removed by a heat treatment at a high temperature, and hydrogenation is carried out with a metal oxide catalyst, thereby manufacturing a solvent product.

Provided is a method of producing naphtha from mixed plastic, the method including the following steps: (a) subjecting the mixed plastic to thermal pyrolysis; (b) separating a product produced in the thermal pyrolysis into first oil having a boiling point of lower than 150&#xb0; C. and second oil having a boiling point higher than that of the first oil; and (c) subjecting the second oil to catalytic pyrolysis.

Method of producing selective naphtha oil through secondary pyrolysis of waste oil

A process for reducing haze in a heavy base oil includes: obtaining a first effluent oil by contacting a hydrocarbon feedstock with a first catalyst including a zeolite of the ZSM-12 family; and obtaining a second effluent oil by contacting the first effluent oil with a second catalyst including a zeolite of the ZSM-48 family. A hydroisomerization catalyst system having reduced haze includes: a first catalytic region having a first catalyst disposed therein, the first catalyst including a zeolite of the ZSM-12 family; and a second catalytic region having a second catalyst disposed therein, the second catalyst including a zeolite of the ZSM-48 family. The first catalytic region is disposed upstream of the second catalytic region.

Process for reducing haze in heavy base oil and hydroisomerization catalyst system having reduced haze

This invention relates to a hydrogen spillover-based catalyst and use thereof, wherein a hydrogen activation metal cluster is dispersed in the form of being encapsulated in a crystalline or amorphous aluminosilicate matrix which is partially or fully structurally collapsed zeolite, thereby exhibiting high hydroprocessing or dehydrogenation activity and suppressed C&#x2014;C hydrogenolysis activity.

Catalyst containing metal cluster in structurally collapsed zeolite, and use thereof

Disclosed herein is a method of simultaneously removing sulfur and mercury from a hydrocarbon material, including: hydrotreating the hydrocarbon material containing sulfur and mercury in the presence of a catalyst including a metal supported with a carrier to convert sulfur into hydrogen sulfide, and adsorb mercury on a metal active site or a carrier of the catalyst in the form of mercury sulfide.
