Hi Len

After similar cracking a fusion problems from combusting glass fibre filters we have been using thin-wall alumina liner tubes inside the quartz reactor column. These prolong the life the reactor tube and have the added advantage of being easily changed and require minimum downtime for de-ashing which can be done at the running temperature.

After cooling and cracking another new quartz reactor column on the C+N
EA I am wondering if anyone has instead tried using thicker walled
ceramic columns normally used for pyrolysis?  Seems to me these are far
more robust and could be easily cleaned out and reused without the
filthy mess left by shattered qtz reactors? 

Anyone tested this? Pros, Cons?
