摘要:
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.

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. An embodiment of the present invention is, through a process which, 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. The solvent product manufactured by the present invention has a high n-paraffin content as compared with a common petroleum-based solvent and a low impurity content, thereby having high quality as a solvent, and also has a high isoparaffin ratio of 15 wt% or more, thereby having good low temperature properties. Since a waste oil, which, when discarded or burned, may be converted into greenhouse gas or hazardous gas such as SO x , NO x , and Cl-containing gases, is converted into an industrially widely used solvent, the present invention is preferred in terms of environment protection.

Provided is a method of producing naphtha from mixed plastic, the method including: a step (a) of subjecting the mixed plastic to thermal pyrolysis; a step (b) of separating a product produced in the thermal pyrolysis into first oil having a boiling point of lower than 150°C and second oil having a boiling point higher than that of the first oil; and a step (c) of subjecting the second oil to catalytic pyrolysis.
摘要:
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-C hydrogenolysis activity.
摘要:
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.
