The Interesting of Solar Energy

Posted on October 17, 2013 ·
Solar energy comes from the sun as fuel to create heat or electricity. Solar technology fall into two categories: passive and active. Passive solar heat generation and provide exposure to the structure. Active solar energy to produce electricity using a technology called the Solar Photovoltaic (PV), or heat, hot water or electric technology called Solar Thermal.

Solar energy is considered environmentally friendly because the sun is a natural source of energy that does not require the burning of fossil fuels and emissions associated online. In addition, because it is considered a renewable energy generated from the sun does not reduce any of the natural resources, and endless.Solar energy, however, is called intermittent source, which means that it is not always there. When it is cloudy or rainy, the sun is not there to give light, and solar energy systems can not produce energy. Therefore, many systems are designed with one of several types of energy storage characteristics, or backup source of energy, such as electricity networks. Additional features allow users to continue to operate the rear even if the sun does not shine.

Renewable Energy

Posted on August 27, 2013 ·
Movement or renewable energy can be defined as the energy that comes from natural sources plus the human time scales such as sunlight, wind, rain, tides, and geothermal heat wave integrated response replaces conventional fuels in four different areas:. Power generation, hot water / space heating, motor fuel, and the city (off–grid) energy.

Based on REN21 2014 report, renewable energy accounted for 19 percent of our energy consumption and 22% of our electricity generation in 2012 and 2013, respectively. Second, during this movement, such as water, wind, solar and biofuels, as well as traditional biomass, accounted for about the same domain as the global power supply. Worldwide investment in renewable technologies and more than US $ 214 billion in 2013, with countries such as China and the United States invested heavily in wind, hydro, solar and biofuels [1].Amendment to a wide area, and various other sources of power, which is concentrated in a few countries. Fast action renewable power and energy efficiency led to the need for security, climate change mitigation, and economic benefits and the national public opinion survey that there is strong support for promoting renewable sources such as solar power and wind power and the national level, at least 30 countries around the world now have a renewable energy accounts for more than 20 percent of the power supply. State renewable energy market is expected to continue to grow in the coming decade and beyond.

Electric Car

Posted on July 16, 2013 ·

All-electric vehicles (EVs) run on electricity only. Electric Cars use the energy stored in a battery (or series of batteries) for vehicle propulsion. Electric motors provide a clean and safe alternative to the internal combustion engine. There are many pros and cons about electric cars. The electric vehicle is known to have faster acceleration but shorter distance range than conventional engines. They produce no exhaust but require long charging times. This page provides articles about electric car technologies. They are propelled by an electric motor (or motors) powered by rechargeable battery packs. EVs have several advantages over vehicles with internal combustion engines (ICEs):

  • Energy efficient. Electric vehicles convert about 59–62% of the electrical energy from the grid to power at the wheels—conventional gasoline vehicles only convert about 17–21% of the energy stored in gasoline to power at the wheels.*
  • Environmentally friendly. EVs emit no tailpipe pollutants, although the power plant producing the electricity may emit them. Electricity from nuclear-, hydro-, solar-, or wind-powered plants causes no air pollutants.
  • Performance benefits. Electric motors provide quiet, smooth operation and stronger acceleration and require less maintenance than ICEs.
  • Reduce energy dependence. Electricity is a domestic energy source.

Paper Presentation in International Graduate Conference on Engineering, Science and Humanity (IGCESH 2013)

Posted on April 17, 2013 ·

I presented a paper in an international conference recently. Following are the details of the paper and abstract:

Zaki Yamani Zakaria, Nor Aishah Saidina Amin, Juha Linnekoski, Thermodynamic Analysis of Glycerol to Ethylene, Presented in International Graduate Conference on Engineering, Science and Humanity (IGCESH 2013), Universiti Teknologi Malaysia, Skudai, Johor. 16-17 April 2013. (PDF)

Thermodynamic Analysis of Glycerol to Ethylene

Abstract—Thermodynamic equilibrium analysis of glycerol steam reforming to ethylene has been investigated based on the total Gibbs free energy minimization method. Equilibrium product compositions for glycerol steam reforming were determined for temperatures ranging from 573–1273 K and GWR (glycerol/water ratio) 1:12 to 2:1 at 1 bar pressure. The objectives of this study are to identify the thermodynamic range of the process operation and study the variation of product distribution. It was found that the formation of ethylene was difficult to accomplish and the amount of ethylene produced is very small. Other means to encourage the formation of more ethylene is required.

Keywords: glycerol to ethylene, glycerol steam reforming, thermodynamic modeling, glycerol conversion, biomass conversion

Workshop at Shanghai, 2011

Posted on December 29, 2012 ·

One of the beauty of being an academician is the opportunities to travel in line of duty. Reasons could be due to attending conference, workshop, research exhibition, research competition, invited speaker, plenary speaker, research collaboration, post doctoral, research attachment and many other things.

Publication in Chemical Engineering Journal

Posted on December 28, 2012 ·

Alhamdulillah, I managed to publish a new manuscript in a Q1 rated journal. The title of my paper is “Catalyst screening for conversion of glycerol to light olefins”, Chemical Engineering Journal 207–208 (2012) 803–813.

Here is the abstract:

Catalyst screening for conversion of glycerol to light olefins

Screening of modified ZSM-5 catalysts for conversion of glycerol to light olefins has been investigated. In this study HZSM-5, Al/ZSM-5, Ca/ZSM-5, Cr/ZSM-5, Cu/ZSM-5, Li/ZSM-5, Mg/ZSM-5 and Ni/ZSM-5 zeolite catalysts were prepared, tested and screened. The catalysts were characterized to relate their properties with catalyst activity. XRD and FTIR characterization results demonstrated that the structure of the catalysts remained intact while BET revealed the surface and micropore areas decreased after metal loading. TPR data exhibited the reduction phenomenon of the catalysts. NH3-TPD analysis indicated that Cu/ZSM5 catalyst has relatively more moderate and strong active acid sites compared to others. GC TCD/FID analysis detected light olefins and paraffins; methane, CO and CO2 in the gaseous product stream. The acidity of the catalyst affected olefin production, but no direct correlation between surface area and olefin yield was observed. The turnover frequency (TOF) for Cu/ZSM-5 and Cr/ZSM-5 catalysts were significantly high comparatively. Cu/ZSM-5 produced the highest light olefins selectivity and yield due to the synergistic effect of the physico-chemical properties between the parent ZSM-5 and the metals.

Research Attachment at Newcastle University

Posted on July 24, 2012 ·

I am very lucky that during my Ph.D, I was able to do my research attachment at Newcastle University from May to June 2012 for 2 months. I was supervised by Prof. Dr. Adam Harvey and Dr. Jon Lee from the Process Intensification Unit, Chemical Engineering Department. During my 2 months stay, my goal was to work on my thermodynamic model for glycerol steam reforming to light olefins. I used combination of Aspen and Matlab software in my efforts to solve the thermodynamic problem.
