Answer: carbon dioxide

Explanation:During separation of air by fractional distillation method, air undergoes compression by increasing the pressure and cooling by decreasing the temperature. After this point air gets converted into a liquid state and the carbon dioxide present in the air, converted into a solid form which is known as dry ice and separated at this point of time.
