What is the type of reactor to be used?
Based on the discussion from the previous part, we have selected fast pyrolysis as the technology we would like to focus on. The reactor that we will be focusing on would be BTG-BTL reactor or simply means an improvised version of a Rotating Cone Reactor (RCR) and engineered into a commercial industrial installation. The RCR technology was initially developed by The University of Twente. Below is a table showing why BTG-BTL reactor is selected.

What is the size of the reactor?
Operating temperature and pressure?
In real, this reactor has a large capacity of 5 tonnes/hour which has a diameter of only 1 meter and height of 2.5 meter which is compact and low investment cost. The estimated temperature would be high as fast pyrolysis takes places in high temperature, which is 450 - 600 °C in the absence of air. After a long research, there is no accurate data to display the accurate temperature. However, based on knowledge of fast pyrolysis, a high pressure is definitely required to undergo this process which is definitely more than 20 bar.
Does it require any heating/cooling? How do you provide that?
This reactor definitely requires a heating and the heating goes up to approximately 700 °C. Besides, this reactor has built-in recovery of excess heat in the form of steam which can be used for heating and electricity production. In this case, this power electricity generated can be used to run the total plant.
