Revisions to improve the operability of the PDU with bituminous coal were completed and evaluated during two short tests. Work aimed at determining the tar yield from bituminous coal was begun. Cold flow testing was resumed to develop means to improve char circulation in the PDU pyrolysis system. Two new devices were developed which show promise. Cold flow modelling confirmed the occurrence of char maldistribution in the original PDU reactor design and the effectiveness of the insert baffle in providing uniform distribution. Char circulation control stability can be improved by adding capacitance to the system thereby dampening surges.
