Pre-sulfidation issue in two-stage hydrocracking reactor systems
Thread Content
For a two-stage hydrocracking reactor, are there any requirements regarding whether to sulfurize Stage 1 first or Stage 2 first during pre-sulfurization, or to sulfurize both at the same time?
We were vulcanized together. What specific requirements are you referring to?
Our pre-vulcanization plan involves two stages first; stage two is initiated once the temperature reaches 280 degrees, which seems to help avoid the peak period of vulcanizing agent usage
