generation biodiesel from Pongomia Pinnata seed oil using a microwave assisted transesterification. Pongomia Pinnata seed oil is obtained after the mechanical extraction of rubber seed is using Soxhlet Extractor. The alcohol used in this research is methanol which is used to react with Pongomia Pinnata seed oil with a base or acid catalyst to produce methyl ester. Acid catalyst used in this research is potassium hydroxide (KOH) and base catalyst used is sodium hydroxide (NAOH). Parameter that concerned

the polymerization is stopped by immersing the test tubes in an ice bath. The contents in the tubes are dissolved in 40 mL of toluene and the different polymers are then precipitated by adding the solutions slowly‚ drop-by-drop‚ into 400 mL of methanol under vigorous stirring. It is very important that the solution is added dropwise

After the injection is complete‚ the lever of the injection loop is pulled down to create a high pressure pump that pushes the sample into the mobile phase of the instrument. This mobile phase‚ which for this experiment will consist of water and methanol‚ transports the samples toward the packed column where it will leave the mobile phase and enter the stationary phase. In this stationary phase‚ the sample is fixed in place for the amount of time it takes for the sample to elute back to the mobile

synthesizing from natural gas‚ associate gas or low rank coal for shipment to users in the surrounding countries would be extremely significant for secure energy supply and environmental conservation. DME is now manufactured by a dehydration reaction of methanol. In order to use DME as a fuel‚ it must be produced at low cost in large quantities. DME synthesis technologies directly from synthesis gas are under development for these years[1‚2]. NKK Corporation has been making progress in the technology

Experimental studies have been reported on extinction and autoignition of methanol and ethanol flames in laminar‚ non uniform flows for both non premixed and premixed flames in counter-flow configuration by Seiser et al. [8]. Numerical investigations in this paper are performed for non-premixed laminar counter-flow flame using

Executive Summary. Aerosol hairspray cans are a cosmetic product used by 86% of women in the United States.(3) The consumer demand for hair products has stayed relatively steady since the invention of hairspray. Industrial suppliers can increase their net profit of aerosol hairspray production by analyzing and possibly optimizing their manufacturing process‚ mores specifically‚ the production of the most widely used aerosol propellant‚ dimethyl ether (DME). The optimization of a thermally coupled
