Temperature<br />
• An increase of temperature (i.e. WAIT) has the following<br />
effects:<br />
– Increases octane<br />
– Decreases the yield (of C5+ fraction)<br />
– Decreases the H2 purity.<br />
– Increases the coke deposit<br />
• A slight increase of temperature (WAIT) through the life of<br />
the catalyst makes up for this activity loss<br />
• Larger <strong>and</strong> temporary changes in temperature are required:<br />
– To change octane - at constant feed quality <strong>and</strong> quantity<br />
– To change feed quantity <strong>and</strong> still maintain octane<br />
– To change feed quality <strong>and</strong> still maintain octane<br />
