**Postgraduate Research Opportunity: Integration of Biomass Gasification and Subsequent Gas Reforming Processes to Maximise the Economic and Environmental Benefits of Sustainable Syngas Production**

**Location**: Department of Process Engineering, Stellenbosch University, Stellenbosch

**Degree level**: Full-time, research-based Masters degree in Chemical Engineering

An opportunity is available for postgraduate research at Masters level to optimise biomass gasification and gas reforming technologies, to improve the commercial and environmental benefits associated with its industrial implementation. Gasification of lignocellulosic plant biomass has been under development for a number of years, and offers unique integration and synergistic opportunities for co-processing of the gasification-product-gas with biogas (from anaerobic digestion), green hydrogen (from solar or wind energy and water electrolysis) and natural gas. Considering the scale of industrial facilities that utilize syngas for either minerals processing or chemical synthesis processes, it is inevitable that a combination of renewable carbons from lignocellulose-gasification and anaerobic digestion be utilized in future. Maximising the potential synergies with co-processing these renewable carbons with green hydrogen and natural gas will provide substantial energy savings, increase the final product yield and maximise their economic and associated environmental benefits.

The present project will consider a range of alternative integration and co-processing/reforming scenarios for the four gas-products of interest. New process technologies such as dry reforming will be included in the definition of these scenarios, as well as careful analysis of the most promising technologies for commercial biomass gasification, such as fixed and fluidized bed. Real-world representative costings curves of these technologies will be attained through consultation of literature, industry and technology suppliers. Using a combination of process simulations and equilibrium predictions, detailed mass&energy balances will be drawn up for optimized scenarios, as the basis for subsequent economic and environmental assessments. Both the cost of syngas production, as a function of raw material prices, as well as the life cycle environmental benefits associated with alternative processing methods, will be considered as a means to select the preferred scenario(s) offering the optimal combination of economic and environmental benefits. These outputs are of substantial relevance to a wide range of industries investigating various approaches to green their processing methods, whom will serve as collaborators in the project.
