Provided is a catalyst composition for the isomerization of n-paraffin which comprises a \u03b2-zeolite having been synthesized according to a dry gel process and contains cerium, the \u03b2-zeolite being characterized in that it has an average particle diameter of 0. The template comprises a template blank shaped for accommodation by an amplifier control panel, the template blank having cut-outs or bores facilitating the application of the template to the amplifier control panel, and the subsequent operation of said control panel. The method of an embodiment of the invention saves the mouse dragging time on the display while performing a mouse operation at the location of the keyboard cursor. The control system may include software and hardware that allow the control system to control one or more of: modulation of one or more by-pass dampers; adjustment of the nozzle outlet area; varying the speed of the fans; the number and staging of fans.
