    (Library Information Services, COMSATS University Islamabad, Lahore Campus., 2025-04-01) Muhammad Zain Feroz; CIIT/FA23-RNE-008/LHR; Dr. Um-e-Salma Amjad; LHR TP 9677
    The objective of this research is to produce Hydrogen, a clean source of energy, through the steam reforming process, from hydrocarbons as feedstock. It emphasizes the development of catalysts that are capable of addressing the challenges of stability and efficiency. This study focuses on the use of tools like DWSIM to determine the operating conditions for enriched hydrogen yield. The research involves catalyst synthesis through the combustion synthesis method to synthesize different catalysts. This method involves using a vaporizer and reactor setup at controlled temperature and pressure. Whereas, after the SR process, the gas composition of the product will be analyzed through the use of a gas analyzer. It will shed light on the efficiency of the process and trace impurities in the product gas. The research focuses on reducing the oxides of carbon in the final product for maximum hydrogen production and to comply with global carbon emission standards.

    Synthesis of Platinum Based Catalyst and Evaluation of its Catalytic Properties
    (Library Information Services COMSATS University Islamabad Lahore Campus, 2021-02-24) Sabiqa Inam; FA19-R06-032; Dr. Um-e-Salma Amjad; LHR TP 7343
    The niobium pentaoxide supported platinum (Pt/Nb2O5) catalyst was successfully synthesized by using a conventional wet impregnation method. The catalytic activity of synthesized catalyst was evaluated for the model reaction of dehydrogenation of methylcyclohexane to toluene and hydrogen. The catalyst was first reduced with hydrogen and then used for experiment. The experiment was performed in the fixed bed reactor within a temperature range of 300°C to 500°C for 3hours. Under the experimental conditions, dehydrogenation of methylcyclohexane was successfully carried out over Pt/Nb2O5 catalyst. Various concentrations of Pt loading on supports have been employed to determine which concentration give better results. A mechanistic study based on thorough description was done by Raman and XRD characterization techniques to determine the structure and elemental composition of the catalyst. Catalytic activity was monitored by the condensate volume and the fractions of gasses produced during reaction. The percentages of gaseous products were analyzed with the help of gas analyzer. The greater volume of condensate was recorded at temperature of 400oC.
