Conversion of isopropyl alcohol to acetone on irradiated zinc oxide*1

Catalytic Oxidative Desulfurization of Fuel by H2O2 In Situ Produced via Oxidation of 2-Propanol

“…As seen from the figure, the sulfur conversion increases steadily from 23.07 (1 h) to 59.26% (4 h), followed by a dramatic increase from 59.26 (4 h) to 98.90% (6 h), and then levels off. Obviously, the sulfur conversion rate from 4 to 6 h is much faster than that in the preceding 4 h, which may be largely attributed to the presence of a long induction period for the oxidation of 2-propanol . In the induction period, the oxidation rate of 2-propanol is slow, which results in a lower production rate of H 2 O 2 , and accordingly a slower sulfur conversion rate.…”

“…Obviously, the sulfur conversion rate from 4 to 6 h is much faster than that in the preceding 4 h, which may be largely attributed to the presence of a long induction period for the oxidation of 2-propanol. 29 In the induction period, the oxidation rate of 2-propanol is slow, which results in a lower production rate of H 2 O 2 , and accordingly a slower sulfur conversion rate. After the induction period, the production of 2-propanol radicals, i.e., (CH 3 ) 2 C • OH, and thus the oxidation of 2-propanol as well as the follow-up oxidation of S-compounds become faster, and a deep sulfur conversion of 99.69% can be achieved in 8 h. In view of the marginal increase of sulfur conversion in the longer period of time, 6 h is suitable and fixed in the following study.…”
