Sample context:

The microriser is a laboratory-scale entrained flow reactor, in which the reaction time can be varied by changing the reactor length. The outline of the equipment is shown in Figure 1. The microriser reactor is placed inside a furnace and can be operated completely isothcrmally and with ideal plug flow for gases and catalyst. Nitrogen is used as a transporting gas for the catalyst from the **catalyst feeder** through a preheat oven to the reactor entrance. The reactor entrance is defined at the point where preheated feed is injected. Heating times arc sufficient to ensure isothermal contacting of catalyst and feedstock. At the end of the reactor the catalyst is separated from the reaction products by a high loaded cyclone (entrance separation efficiency >99.99%). Stripping of the catalyst takes place post-run and it has been verified that the stripping procedure does not intluence the (catalytic) conversion and product yields. Only experiments with a mass recovery of 97±2 wt% are considered successful (due to liquid hold-up in the product collection system, mass recoveries of 100% are impossible).
