    The focus of my studies is on biomass gasification, in-situ carbon capture and post-combustion carbon capture using solid adsorbents. Later on I diverted my project towards direct utilisation of CO2 using sunlight and designed and developed a concept prototype of world's first artificial leaf which is able to directly convert CO2 from gas phase to solid carbon. The underlying technology is being patented.

  • Solid Particles’ Recirculation Distribution in Calcium Looping Post-Combustion Carbon Capture

    International Journal of Greenhous Gas Control

    Post-combustion capture of CO2 from the flue gas of power plants by calcium looping, in which lime is used to capture CO2, is currently a promising technology. The decay in CO2 uptake capacity of natural limestone is an intrinsic disadvantage of this technology, and the design of more stable sorbents has become an important goal. Techno-economic calculations that examine calcium looping must take into account this decay in capacity, and this has to date been accomplished using a formula for the…

    Post-combustion capture of CO2 from the flue gas of power plants by calcium looping, in which lime is used to capture CO2, is currently a promising technology. The decay in CO2 uptake capacity of natural limestone is an intrinsic disadvantage of this technology, and the design of more stable sorbents has become an important goal. Techno-economic calculations that examine calcium looping must take into account this decay in capacity, and this has to date been accomplished using a formula for the population distribution of particles in the cycling system. However, the formula has some limitations that make it less suited to very stable sorbents, making it difficult to incorporate newer materials in such calculations. We developed a more general formula for the population distribution of solid particles in processes involving recirculations, and compared it with the widely used equation in the calculation of several process metrics. Particular consideration was given to conditions relevant to enhanced or tailored sorbents, for which our modified formula was well suited. In addition, the impacts of calcium looping process configuration on this generalized population distribution of solid particles were studied from mathematical and operational perspectives.

  • Fully Integrated Stand-Alone Device for Gas-Phase CO2 Reduction Using Sunlight: Proof of Concept

    228th ECS Meeting, Pheonix, AZ, USA.

    The conversion of CO2 to fuels can be a promising pathway to reduce the carbon intensity of the economy, if the energy required for its conversion is supplied from renewable sources. We showcase a fully integrated, wireless, stand-alone unbiased photoelectrochemical cell (PEC) for the conversion of CO2 and H2O to chemicals and fuels in gas phase. Simulated sunlight at 1 Sun intensity is used to drive the conversion reaction. Proof-of-concept experiments show that the device is operational in…

    The conversion of CO2 to fuels can be a promising pathway to reduce the carbon intensity of the economy, if the energy required for its conversion is supplied from renewable sources. We showcase a fully integrated, wireless, stand-alone unbiased photoelectrochemical cell (PEC) for the conversion of CO2 and H2O to chemicals and fuels in gas phase. Simulated sunlight at 1 Sun intensity is used to drive the conversion reaction. Proof-of-concept experiments show that the device is operational in dilute CO2 streams (10% CO2, 2% H2O, Ar balance) as well as in concentrated CO2 streams (98% CO2, 2% H2O). With a Cu sheet as the cathode catalyst, the device offers a CO2 reduction selectivity of ~50%; when Cu2O nanorods are employed, the selectivity toward CO2 reduction increases to ~90%. Experiments related to improving the performance of the device, testing other catalyst materials, and detecting the products is ongoing. The cell is lightweight, built of earth-abundant materials, and easy to assemble and scale. Further, it operates in dilute CO2 streams and the gas-phase operation facilitates the separation of liquid products. Thus the device represents a promising avenue toward the direct conversion of CO2 from flue gas or even air, without the need to first capture the CO2.

  • Automated process flow sheet synthesis for membrane processes using genetic algorithm: role of crossover operators (Accepted)

    ESCAPE 26

    Process flow sheet synthesis is the most important aspect of designing any chemical production plant. Automated chemical process flow sheet synthesis refers to systematic computational techniques that simultaneously consider operating conditions, equipment design, equipment type, and flow sheet structure. In optimization-based process flow sheet synthesis, optimization methods such as mathematical programing and evolutionary algorithms, i.e. genetic algorithm (GA), are used as advantageous…

    Process flow sheet synthesis is the most important aspect of designing any chemical production plant. Automated chemical process flow sheet synthesis refers to systematic computational techniques that simultaneously consider operating conditions, equipment design, equipment type, and flow sheet structure. In optimization-based process flow sheet synthesis, optimization methods such as mathematical programing and evolutionary algorithms, i.e. genetic algorithm (GA), are used as advantageous tools to select a high performance flow sheet by screening large numbers of possible flow sheets among a data set of flow sheets or superstructure. In this study, we expanded GA role to include flow sheet generation. In addition, we proposed and implemented modified Greedy-sub tour crossover operator and compared it with four other commonly used crossover operators in a GA optimization-based process synthesis method. The proposed method was applied to generate the optimum process flow sheet for a multicomponent membrane-based CO2 capture process. Reciprocal of CO2 purity was defined as the objective function to be minimized. Within the defined constraints and using the random-point crossover, the purity of 0.8272 was achieved which was slightly improved in comparison to the simplest crossover operator applied (3.4%). In addition, the least variability in the converged solution (flow sheet) and CO2 purity was observed for random-point crossover operator, which indicates closeness of the solution to the global optimum and repeatability of the algorithm. The proposed crossover operators, improved convergence speed of algorithm by 77.6%.

  • A model-based approach for analysis of working fluids in heat pipes

    Applied Thermal Engineering

    In this study we develop a dimensionally reduced mathematical model for a heat pipe using a set of new dimensionless numbers and show how this model can be used to analysis and predict the effect of using different working fluids on thermal resistance of a heat pipe. We use the model to design new working fluids to meet pre-specified characteristics of the heat pipe. The presented method has generic application.

  • Optimum CaO:Coal Ratio in Enhanced Hydrogen Production

    4th Sino‐Australian Symposium on Advanced Coal and Biomass Utilisation Technologies

    The practice of enhancing hydrogen (H2) production from coal pyrolysis and gasification by adding CaO has attracted much interest. However, the optimal ratio of CaO:coal has not been
    determined. We aimed to find this ratio for Australian lignite and bituminous coals by studying
    their pyrolysis in the temperature range of 600−800 °C using thermogravimetry and mass
    spectrometry. The effects of pyrolysis temperature on the optimum CaO loading, the…

    The practice of enhancing hydrogen (H2) production from coal pyrolysis and gasification by adding CaO has attracted much interest. However, the optimal ratio of CaO:coal has not been
    determined. We aimed to find this ratio for Australian lignite and bituminous coals by studying
    their pyrolysis in the temperature range of 600−800 °C using thermogravimetry and mass
    spectrometry. The effects of pyrolysis temperature on the optimum CaO loading, the
    effectiveness of CaO addition on coal gasification, and the improvement in direct and indirect H2
    yields are discussed for each type of coal. The highest H 2 yield from pyrolysis at the most recommended gasification temperature of 650 °C was obtained for a CaO-to-coal ratio of nine to one by mass (equivalent to 10 wt% coal in feed). This optimal ratio varied from 5:1 to 19:1 depending on the temperature, heating rate, and coal type.
