ResearchResearch interests
My research is focused on achieving net zero in food, energy and environment systems. More importantly, I have linked the sustainability with digital technology, through digital sustainable systems, by establishing modeling and simulation tools, which are used for optimization and decision-making in industry.
1. Sustainable Energy Systems:
aiming at lowering energy demands and adverse environmental impacts, innovative
processes and plant intensification schemes are developed and investigated. Based on
biomass, integrated facility to simultaneously produce green energy, food additives and
useful materials is proposed. Here, plant-wide simulation is used for designing the
processes, analysing resources and energy flows as well as evaluating the economic
feasibility and environmental impacts.
2. Sustainable Environment Systems:
this project focuses on ‘waste to wealth’ process based on circular economy principles to
upscale waste. Simulation tools are used to develop the processes and evaluate the feasibility.
3. Sustainable Food Systems:
aiming at producing high quality food materials and achieving net zero in food systems, solar
energy and enhanced methods (i.e. by using microwave, infrared, ultrasound) are proposed
and investigated in food processing. Similarly, active packaging combined with
understanding of food material science has been used to lower the refrigeration load during
food distribution.

In this study, a comprehensive process for production of an environmentally friendly octane booster (acetophenone) from lignin is presented, along with a detailed techno-economic analysis. Recognizing that much of the prior research on octane boosters has been confined to experimental lab-level investigations, this study develops comprehensive process design to unravel the intricacies of large-scale acetophenone production. The acetophenone production process involves catalytic hydrogenolysis, which also yields phenol as a valuable side product. Based on the process flow diagram, mass and energy balances were developed, revealing significantly improved yields and purity of acetophenone compared to industry standards, reaching 0.74 kg acetophenone per kg of lignin and 99 wt%. In the techno-economic analysis, calculations involving fixed capital investment (FCI), operating costs, and working capital were conducted based on a feed of 100 kg/h of dry lignin. The results indicate FCI at 2.72 million USD, operating costs at 1.09 million USD per year, and working capital at 0.57 million USD. Assuming a 20-year operational lifespan, the payback period is estimated at 6.09 years, as depicted by the cumulative cash flow diagram. Moreover, techno-economic analysis demonstrates a net present value (NPV) of 3.24 million USD at a 10% discount rate, an internal rate of return (IRR) of 22.73%, and a return on investment (ROI) of 34.39%. These positive outcomes underscore the robust profitability of the proposed acetophenone production plant derived from lignin. Additionally, a sensitivity analysis on the IRR indicates that increasing the production capacity could further enhance profitability, reaffirming the feasibility of the plant's operation. Crucially, this study highlights the potential for sustainable and economically viable production of acetophenone, offering an environmentally friendly alternative to toxic octane boosters and advancing the development of sustainable fuel additives.
