Can methanol react with C4 at room temperature?

In the process, methanol and C4 are mixed and heated by a heat exchanger before entering the reactor. However, this heat exchanger uses the MTBE coming out of the bottom of the catalytic distillation tower for heat exchange. Because there is no MTBE at the beginning of the construction, how to control the temperature of the reactor at this time? Is it okay without heating?
http://bbs.hcbbs.com/viewthread.php?tid=336752 Here are the steps for commissioning and commissioning of a certain MTBE device in the forum for reference.
Generally speaking, there should be a feed heater. If there is no room temperature feed, there should be no problem. Because the catalyst in the new device is highly active, it can react at 30 degrees Celsius.
Our device has a preheater, but this preheater exchanges heat with MTBE. However, there was no MTBE when we first started working. I wonder if you have ever seen this kind of process.
If it is a newly started device, due to the high activity of the catalyst, the reaction can be carried out at a lower temperature, but it should not be lower than 25 degrees Celsius.； The specific temperature and degree of reaction are related to the selected catalyst. The activities of catalysts from different manufacturers are not the same.
Can the catalyst react at room temperature? What is the lowest temperature? Are there any process technology requirements for newly purchased catalysts?
When I first started working, there was a reaction even without heating. However, the feed temperature is not easy to be lower than 30°C. In addition, to increase the reactor bed temperature, the feed temperature should be raised to above 40°C. When the bed temperature rises, the feed temperature should be lowered.
If the temperature is too low, it will definitely not react. If you keep circulating during the start-up process, there may be reactions. If the material is discharged without circulating, it will be very difficult. Welcome to join the group 106543163 for discussion.
1# The flying eagle catalyst can react at room temperature
Reply 3# jianghumoren123 You are right about one thing. What I mean is that it is not necessary to heat it when the work is just started.
