摘要:
The present invention provides a zeolite catalyst having an MRE structure for hydroisomerization. The zeolite catalyst has an adsorption volume ratio of lutidine to collidine measured by FTIR using lutidine and collidine as adsorbents of greater than 3 and less than or equal to 10. The present invention further provides a method of hydroisomerization for a feedstock, including subjecting the feedstock to a hydroisomerization 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 -1 , and a hydrogen/feedstock ratio of 45 to 1780 Nm 3 /m 3 in the presence of the zeolite catalyst.
