Status Of Biodiesel Research And Development In Pakistan, Abdul Aziz Abdul Raman
Status Of Biodiesel Research And Development In Pakistan, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
Performance of biodiesel in engines is well established and biodiesel is currently adjudged as a low carbon fuel with the most potential of replacing fossil fuels. The fossil fuel sources are dwindling in Pakistan resulting in importation of about 8.1 million tonnes at approximately US$ 9.4 billion per annum. In the ambit of this justification, augmenting the energy scarce resources in Pakistan through intense harnessing of the varied biodiesel sources can adequately address the deficiency and can ensure energy security. Towards this end, the progress attained in biodiesel related researches in Pakistan are evaluated and presented with the view of …
Viscosities And Densities Of Binary And Ternary Blends Of Palm Oil + Palm Biodiesel + Diesel Fuel At Different Temperatures, Abdul Aziz Abdul Raman
Viscosities And Densities Of Binary And Ternary Blends Of Palm Oil + Palm Biodiesel + Diesel Fuel At Different Temperatures, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
Vegetable oil-based fuels are promising alternative fuels for diesel engines because of their environmental and strategic advantages. In this work, binary and ternary blends of palm oil, biodiesel, and diesel fuel were prepared, and dynamic viscosities and densities of blends were measured as functions of temperature. The binary and ternary blends demonstrate a temperature-dependent behavior, and viscosities and densities decreased nonlinearly and linearly with temperature, respectively. The evaluation of the measured viscosities of binary and ternary blends was completed, and the best correlation was obtained by a polynomial regression. © 2010 American Chemical Society.
Density Of Jatropha Curcas Seed Oil And Its Methyl Esters: Measurement And Estimations, Abdul Aziz Abdul Raman
Density Of Jatropha Curcas Seed Oil And Its Methyl Esters: Measurement And Estimations, Abdul Aziz Abdul Raman
Abdul Aziz Abdul Raman
Density data as a function of temperature have been measured for Jatropha curcas seed oil, as well as biodiesel jatropha methyl esters at temperatures from above their melting points to 90 ° C. The data obtained were used to validate the method proposed by Spencer and Danner using a modified Rackett equation. The experimental and estimated density values using the modified Rackett equation gave almost identical values with average absolute percent deviations less than 0.03% for the jatropha oil and 0.04% for the jatropha methyl esters. The Janarthanan empirical equation was also employed to predict jatropha biodiesel densities. This equation …
