Stainless steel reaction products contaminate catalyst


I have a 316 Stainless Steel tube , I used it as a reactor for my PHD project, It's surrounded with a furnace, I heat it up to 800 °C but my reaction temperature is between 400-500 °C , I will use oil, catalyst and N2 gas also, I found it discoloured and some black stuff or scale was there , I am afraid this will contaminate my catalyst , during process. Can you tell me what shall I do? Any suggestions please? Can I use a ceramic tube as another tube or any lining inside?
