    • Characterization of coagulation active agent from moringa oleifera for water turbidity and hardness removal 

      Nurfahasdi, Meutia; Fahmi, Muhammad Ridwan, Dr.; Umi Fazara, Md. Ali, Dr.; Salsuwanda, Selamat (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      The objective of this study was to explore the capacity of the coagulation active agent that extracted from Moringa oleifera (MO) by various solutions for turbidity and hardness removal in raw water sources. The extracted ...

    • Catalytic dehydrogenation of methylcyclohexane (MCH) to toluene in a palladium/alumina hollow fibre membrane reactor 

      Mohd Irfan Hatim, Mohamed Dzahir, Dr.; Umi Fazara, Md. Ali, Dr.; Muhammad Syarhabil, Ahmad, Dr.; Fahmi, Riduwan (Malaysian Technical Universities Network (MTUN), 2012-11-20)
      A compact multifunctional Pd/alumina hollow fibre membrane reactor (HFMR) has been developed and used for the catalytic dehydrogenation of methylcyclohexane to toluene. The developed HFMR consists of a thin and defect-free ...

    • Effect of dolomite on pyrolysis of rice straw 

      Razi, Ahmad; Nasrul, Hamidin, Dr.; Umi Fazara, Md. Ali, Dr. (2013)
      A study of catalytic pyrolysis on rice straw was carried out in a fixed-bed reactor. The objectives were to determine the effect of dolomite catalyst on the distribution of product yield and bio-oil characterization. The ...

    • Performance evaluation of okra (abelmoschus esculentus) as coagulant for turbidity removal in water treatment 

      Fahmi, Muhammad Ridwan, Dr.; Nasrul, Hamidin, Dr.; Che Zulzikrami, Azner Abidin; Umi Fazara, Md. Ali, Dr.; Mohd Irfan Hatim, Mohamed Dzahir (Trans Tech Publications, 2014)
      The objective of this study is to evaluate the performance of turbidity removal in water by using Okra (Abelmoschus esculentus) as natural coagulant. The coagulation active agent in various Okra sections was extracted with ...

    • Physicochemical properties of pyrolitic carbon black from waste tyres 

      Umi Fazara, Md. Ali, Dr.; Ishak, Jainoo; Khairul Nizar, Ismail, Assoc. Prof. Dr.; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr.; Fahmi, Muhammad Ridwan, Dr. (Trans Tech Publications, 2014)
      Waste tyres which are mainly generated from automotive industries have become a major environmental problem to the local authorities, the tyre industries and tyre dealer. When tyres are no longer usable due to worn-out, ...

    • Characterization of bio-oil from palm kernel shell pyrolysis 

      Nasrul, Hamidin; Umi Fazara, Md. Ali; Che Zulzikrami Azner, Abidin; Razi, Ahmad (Faculty of Mechanical Engineering, Universiti Malaysia Pahang, 2014-12-01)
      Pyrolysis of palm kernel shell in a fixed-bed reactor was studied in this paper. The objectives were to investigate the effect of pyrolysis temperature and particle size on the products yield and to characterize the bio-oil ...

    • Electrochemical reduction of carbon dioxide into formate 

      Tan, Tiek A.; Sara Yasina, Yusuf; Umi Fazara, Md. Ali (Taylor's University College, 2015)
      The electrochemical reduction of CO2 dioxide into HCOO- on a Sn cathode is well described in literature. However, the issue of deactivation and loss of Sn and a suitable non-aqueous supporting electrolyte remains unresolved. ...
