Deactivation by coke deposition is one of the most important challenges during reforming processes. High active and coke resistant catalysts, Ni-Y₂O₃-Al₂O₃ aerogel, were used in dry reforming reaction and an innovative regeneration process using in situ CO₂ was proposed. Results showed that the catalytic activity is recovered using in situ CO₂ coke gasification at 650-700 °C. However, temperature higher than 700 °C causes deactivation by sintering. An extended test of 10 successive reforming/regeneration cycles at 700 °C was performed using a catalyst containing 2.5 wt% of Y₂O₃ and the catalytic activity is completely preserved. CO₂ regeneration at same temperature of dry reforming proved to be an excellent alternative to conventional air oxidation reactions to remove the coke. This advantageous catalyst regeneration not only produces useful CO by reaction between coke and CO₂, but also allows the maintenance of operating conditions in reactor and enables the use of greenhouse gas.

焦炭沉积引起的失活是重整过程中最重要的挑战之一。高重活性和耐焦炭催化剂Ni-Y ₂ O ₃ -Al ₂ O ₃气凝胶被用于干重整反应，并提出了一种利用原位CO ₂的创新再生方法。结果表明，在650-700°C下使用原位CO ₂焦炭气化可恢复催化活性。但是，高于700°C的温度会导致烧结失活。使用含有2.5 wt％的Y ₂ O ₃的催化剂在700°C下进行了10个连续重整/再生循环的扩展测试并完全保留了催化活性。事实证明，在干重整的相同温度下进行CO ₂再生是常规空气氧化反应去除焦炭的绝佳替​​代方法。这种有利的催化剂再生不仅通过焦炭和CO ₂之间的反应产生有用的CO ，而且还允许维持反应器中的操作条件并能够使用温室气体。
