用蒸汽或者工艺余热

或者工艺余热产蒸汽再加热，安全

关键还是反应的方式或者反应器的型式，如果用管式反应器可能直接用电加热。

用加热炉加热，用蒸汽导热较好

可以用炉子直接加热。

是不是可以考虑用远红外加热

我们这用的是电加热！导热油！工作温度在450-500之间！叫苏海导热油，具体型号就不清楚啦！你问问厂家吧！

如果介质没有特殊要求的话用管式加热炉直接加热是可选的方案。

360Deg C op temp is quite high, (1) if use steam, the steam must be super pressure steam boiler and pipeline, so no steam. (2) hot oil heater is an another choice, however, most synthesis oil can not be overheat up to 360degC because the oil will be decomposed soon. so, no hot oil heater (3) directed fired heater, burn natural gas or propane, or called furnance, which can be a suitable choice for your requirement.
which process your company used finally? can u update to us? thx

可以用电直接加热，简单实用。

安全的做法：用液化气加热石英砂，将反应器埋在石英砂中。优点：安全，稳定，可以高温。
