摘　　要：重质油加工过程中的过剩碳质可以通过气化反应生产H2。笔者探讨了类似催化裂化待生剂上焦炭制氢的技术问题。实验表明,空气烧焦时,烟气中CO含量随原料气O2浓度的增加而增加;在扩散控制区,温度升高不利于CO含量的增加。水蒸气或CO2与焦炭反应的有效气体(CO+H2)的产率为3.43l/g(以1gC计,以下同),但反应速率较低,910℃反应15min时,消炭率在50%(质量分数,以下同)左右。水蒸气与O2为反应气体时,有效气体产率在1.9l/g左右,910℃反应10min时,消炭率在90%以上。For deep upgrading heavy oil the surplus of carbon and shortage of hydrogen in the end products will occur. In order to self balance the ratio of hydrogen to carbon in some extent, it is worthwhile to convert the surplus carbon originated in feed to hydrogen by watergas reaction in the regenerator system of FCCU, thus the refining and gasification process could be combined and this process is named “refining and gasification combined technology”. It was found that during the regeneration of catalyst by a mixture of N2 and O2, the content of CO in flue gas increases with the increase of O2 content in the mixture. In the diffusing control region, temperature rising is bad for increasing CO content. The yield of potent gas （CO＋H2） is about 3.43 l/g （Calculated based on 1 g carbon） in the reaction of steam or CO2 with coke. But the mass fraction of reacted coke is around 50% in 15 rain at 910℃. As for the reaction of coke with steam and O2 , the potent gas yield is about 1.9 l/g and the mass fraction of reacted coke is over 90% in 10 rain at 910℃.
