发明名称	PROCESS FOR THE ENHANCEMENT OF CYCLE LIFE OF A ZINC-CHROMIUM BASED CATALYST IN THE SYNTHESIS OF 2-METHYLPYRAZINE
摘要	<p>The present invention relates to enhancement of the cycle life of a zinc chromium based catalyst used in the synthesis of 2-methylpyrazine by increasing the reaction temperature step-wise, starting from a low temperature, while monitoring the levels of total conversion and selectivity towards pyrazine. The catalyst can be regenrated after each cycle of use without substantial loss of activity.</p>
