Methods for regeneration of molecular sieves include pressure change (as in oxygen concentrators), heating and purging with a carrier gas (as when used in ethanol dehydration), or heating under high vacuum.

Regeneration temperatures range from 175°C to 315°C depending on molecular sieve type. In contrast, silica gel can be regenerated by heating it in a regular oven to 120°C (250°F) for two hours.

For regeneration of molecular seive 200 - 300°C temperature is enough. This is the right answer.

For regeneration 200-300 degree C temp is enough, no need to heat above 1000 degree.
