A comparison of the selectivity for minor products formed from the same feedstock on LaX and LaY has shown that the two catalysts differ very little in their conversion of the feed. There is, however, a marked difference between the two catalysts in their activity toward short chain product olefins. These are rapidly saturated, cracked or turned to coke by the X catalyst.
