Abstract
A method for producing a hydroisomerization catalyst includes a first step of preparing a support precursor by heating a mixture containing an ion-exchanged zeolite and a binder, the ion-exchanged zeolite being prepared by ion-exchanging an organic template-containing zeolite which contains an organic template and has a one-dimensional pore structure including a 10-membered ring in a solution containing ammonium ions and/or protons, at a temperature of 250 to 350° C. under N2 atmosphere, and a second step of preparing a hydroisomerization catalyst, which is prepared by calcining a catalyst precursor, the catalyst precursor being prepared based on the support precursor containing a platinum salt and/or a palladium salt, at a temperature of 350 to 400° C. in an atmosphere containing molecular oxygen, the hydroisomerization catalyst containing a support which includes a zeolite and carries platinum and/or palladium.
