    The right silica to alumina ratio (SAR) alone does not make a perfect dewaxing catalyst but is for sure one of the key parameters for a well performing catalyst. The dewaxing temperature and hence the catalyst activity is definitely a function of the SAR. The example in Fig 5 shows that an already excellent catalyst could be further improved as concerns n-paraffin conversion by optimizing the
