Claims15
An isomerization catalyst adapted to isomerize a first straight-chain olefin to a second straight-chain olefin different therefrom in a double bond position in the presence of 20 ppm by volume or more of molecular oxygen, comprising:
- Si;
- and
- Al;
- wherein an amount A1 of total acid sites measured by ammonia temperature programmed desorption is 0.11 mmol/g or less
- wherein a ratio A2/A1 of an amount A2 of acid sites measured in a temperature range of 600° C. or more to the amount A1 of the total acid sites measured by ammonia temperature programmed desorption is 0.03 or more.
