1. A production method for indan and hydrindane, comprising:
reacting by introducing a raw material composition including 3a,4,7,7a-tetrahydroindene, optionally hydrogen molecules, and optionally oxygen molecules into a continuous reactor including a solid catalyst containing platinum, and bringing the raw material composition into contact with the solid catalyst under conditions of 150° C. to 350° C. to obtain a reaction product including indan and hydrindane,
wherein a ratio (CH2/C0) of an amount CH2(mol/min) of the hydrogen molecules introduced into the continuous reactor per unit time with respect to an amount C0(mol/min) of the 3a,4,7,7a-tetrahydroindene introduced into the continuous reactor per unit time is 1 or less, and
a ratio (CO2/C0) of an amount CO2(mol/min) of the oxygen molecules introduced into the continuous reactor per unit time with respect to an amount C0 of the 3a,4,7,7a-tetrahydroindene introduced into the continuous reactor per unit time is 0.1 or less.
