Abstract
According to an aspect of the present invention, provided is a zeolite catalyst having an MRE structure for hydro-isomerization. The zeolite catalyst has an adsorption volume ratio of lutidine to collidine measured by Fourier-transform infrared spectroscopy (FTIR) using lutidine and collidine as adsorbents of greater than 3 and less than or equal to 10. According to an aspect of the present invention, provided is a method of hydro-isomerization for a hydrocarbon feedstock, including subjecting the hydrocarbon feedstock to a hydro-isomerization reaction under conditions of a temperature of 200° C. to 500° C., a hydrogen pressure of 1 to 200 atmospheres, a liquid space velocity (LHSV) of 1.0 to 10.0 hr, and the hydrogen/feedstock ratio of 45 to 1780 Nm/min the presence of the zeolite catalyst.
