Provided are a separator and an electrochemical device using the same, in particular, a separator having significantly low heat shrinkage even at a high temperature and also significantly improved adhesive strength by including inorganic particles having specific fluorescence properties in the separator, and an electrochemical device using the same.

Separator and electrochemical device using the same

The present disclosure provides a catalyst for SRO reactions. The catalyst includes a solid acid material and a metal. In this case, pores of the catalyst corresponding to at least 20% of the total pore volume of the catalyst have a pore size of 10 nm or more. The present disclosure also provides a method of using the catalyst.

Catalyst for selective ring-opening reaction and method of using same

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

Disclosed herein is a method of making activated EU-2 zeolite, including: pores having a diameter of 30 to 40 &#x212b; while maintaining the crystal structure of the EU-2 zeolite; and pores having a diameter of 40 to 200 &#x212b;, wherein the volume of the pores having a diameter of 30 to 40 &#x212b; is 0.01 to 0.06 cc/g, and the volume of the pores having a diameter of 40 to 200 &#x212b; is 0.07 to 0.4 cc/g.

Method of preparing an activated EU-2 zeolite

In a specific example according to the present invention, a method is disclosed in which a catalytic reaction is used in order to convert acetic acid, which has been produced by the biological processing or physicochemical processing of biomass, into an aromatic compound constituting a raw material for a high-added-value product such as BTX and, more particularly, p-xylene.

Method for producing aromatic compound from biomass-derived acetic acid

Disclosed herein is an activated EU-2 zeolite, including: pores having a diameter of 30 to 40 &#x212b; while maintaining the crystal structure of the EU-2 zeolite; and pores having a diameter of 40 to 200 &#x212b;, wherein the volume of the pores having a diameter of 30 to 40 &#x212b; is 0.01 to 0.06 cc/g, and the volume of the pores having a diameter of 40 to 200 &#x212b; is 0.07 to 0.4 cc/g.
