The roles of a metal catalyst and hydrogen donors in thermal cracking were studied. The results were compared with those for a typical acid-type cracking catalyst (EMKAT). The role of the metal catalyst in thermal cracking was shown too consist of hydrogen-transfer reactions in mainly non-ionic forms. The ease of dehydrogenation of the hydrogen donor determined the degree of suppression of the cracking reactions.

重油原料模型组分在Metaland酸催化剂存在下裂化条件下的转化比较分析

研究了金属催化剂和氢供体在热裂解中的作用。将结果与典型的酸型裂化催化剂 (EMKAT) 的结果进行比较。金属催化剂在热裂解中的作用也显示出主要是非离子形式的氢转移反应。供氢体脱氢的难易程度决定了裂化反应的抑制程度。
