Post-Doctoral Fellow Job Opening on Catalysis and Methanation of Syngas
The Department of Chemical and Biological Engineering at the University of British Columbia (UBC) invites applications for a Postdoctoral Fellow (PDF) position supervised by Professors Kevin Smith, Naoko Ellis, and Xiaotao Bi. The PDF position will be located at UBC’s Vancouver campus.
Project background:
The overall objective of this project is to evaluate and scale up the forest biomass residues to renewable natural gas technology via performing experiments in a pilot plant consisting of a steam-oxygen two-stage fluidized bed gasifier, prototype syngas clean-up fixed bed reactors, water-gas shift reactor and two-stage methanation reactors to identify the optimal operating conditions of the pilot gasifier and the prototype reactors using a side stream of syngas from the UBC two-stage steam/oxygen pilot gasifier.
A prototype water-gas shift reaction and methanation reaction system with a capacity of 10 L/min syngas conversion capacity has been constructed and commissioned. The unit includes a compression station to accept the syngas produced from the UBC pilot two-stage gasification plant with a biomass feed rate of 25 kg/hr. The water-gas shift reaction and methanation catalysts will be used in the study. Catalysts properties such as specific surface area, pore size and distribution, chemical composition and coke deposition will be characterized using instrument such as BET, XPS, XRD, before and after use, to evaluate the catalyst deactivation. Both water-gas shift and methanation catalyst performance will be evaluated using bottled simulated syngas and a side stream of the real syngas generated from the two-stage biomass gasification plant. Outstanding issues to be addressed by experiments with integrated biomass gasification-methanation pilot-facility include (1) tolerance of catalysts to sulphur compounds in the syngas, (2) tolerance of catalysts to chlorinated compounds and nitrogen compounds in the syngas, (3) tolerance of catalysts to tar content in the syngas, (4) efficiency and longevity of water-gas shift and methanation catalysts with feedstock variation (e.g. sawdust, hog fuels-mixture of bark and sawdust, salt-laden hog fuels).
