【Daily Question No. 155】June 4, 2018: Regarding the influence of the hydrogen-to-oil ratio on the hydrocracking reaction process, which of the following statements is incorrect? ( ) A. When the hydrogen-to-oil ratio in the process is low, it results in a significant decrease in the hydrogen partial pressure from the catalyst bed inside the reactor to the reactor outlet, compared to the value at the inlet. B. An increase in the hydrogen-to-oil ratio essentially leads to an increase in the hydrogen partial pressure during the hydrocracking reaction process. C. One of the reasons why a higher hydrogen-to-oil ratio is required in hydrocracking is that it facilitates heat removal from the catalyst bed. D. The value of the hydrogen-to-oil ratio has no effect on the changes in the hydrogen partial pressure during the reaction process. Changes in hydrogen partial pressure are only related to hydrogen consumption. Answer: D.
