Co-gasification bench-scale installation is shown in Fig. 1. The
reactor was a bubbling fluidised bed gasifier made of a refractory
steel pipe. The reactor was circular in cross-section with an inside
diameter of 80 mmand with a height of 1500 mm. The feeding system
was water cooled to avoid some clogging, that might be due to
pyrolysis of the feedstock, prior to the entry into the gasifier, especially
when PE was used in the feedstock. A nitrogen flow was also used to help waste feeding, to avoid the formation of a compact
plug, due to some pyrolysis of the feeding, and to prevent gas back
flow.
