    • Biodiesel production from rubber seed oil using activated cement clinker as catalyst 

      Jolius, Gimbun; Shahid, Ali; Chitra Charan Suri Charan, Kanwal; Liyana Amer, Shah; Nurul Hidayah, Muhamad @ Ghazali; Chin, Kui Cheng; Said, Nurdin (Malaysian Technical Universities Network (MTUN), 2012-11-20)
      This paper presents the potential of limestone based catalyst for transesterification of high free fatty acid (FFA) rubber seed oil (RSO). Pre-calcinated limestone known as clinker was activated using methanol and ...

    • A CFD analysis on the effect of vortex finder and cylindrical length on cyclone hydrodynamics and centrifugal forces 

      Luqman, Chuah A.; Jolius, Gimbun; Thomas, S. Y. Choong; A., Fakhru’l-Razi (The Institution of Engineers, Malaysia, 2009-06)
      The article presents a Computational Fluid Dynamics (CFD) calculation to predict and to evaluate the flow field and centrifugal forces of gas cyclones. The numerical solutions were carried out using commercial CFD code ...

    • Evaluation on empirical models for the prediction of cyclone efficiency 

      Jolius, Gimbun; Chuah, Luqman Abdullah, Assoc. Prof. Dr.; Choong Thomas, Thomas Shean Yaw, Assoc. Prof. Dr. Ir.; Fakhru’l-Razi, Ahmadun, Prof. Dr. (The Institution of Engineers, Malaysia, 2006-09)
      A numerical simulation on cyclone collection efficiency is presented. The simulations deal with tangential inlet cyclones with relatively low solids loading (<10 g/m3) and for cyclone diameter from 0.01 to 3 m. The ...
