Theory: In the production of biodiesel from cooking oils (glycerides) and methanol are combined with sodium hydroxide as a catalyst. This causes the oils to break apart and reaction of the oils with the methanol. As seen in Figure 1‚ this produces biodiesel (in the form of esters) and glycerol. Figure 1: The production of biodiesel (esters) from glyceride (cooking oils) and an alcohol (methanol). In combustion‚ a substance can be completely or incompletely combusted. In complete combustion‚

CASE 5 Why Did Global Food Prices Rise? Case Summary For the past 25 years‚ food prices have been declining due to increased productivity and output from the farm sector worldwide. In 2007 however‚ this changed. There are two main explanations to this. The first is an increased demand for food in rapidly developing nations such as China and India. Meat in particular has contributed to the rising prices as farmers have to feed their animals an extensive amount of grain in order to keep up with

Canada and America produce canola. * Canola is best grown as a winter crop in soil with pH level between 5.5-8.3. It will grow well in most sites as long as the soil is well drained. * Canola is normally grown in acres and can be double cropped with winter wheat

Biodiesel Fuel The biggest problem the United States faces today when we talk about becoming energy independent is replacing the gas we use to power our vehicles. When we talk about replacing gasoline as the fuel we use to power our vehicles‚ biomass‚ hydrogen‚ and fuel cells are the three most talked about alternatives. Biomass‚ which is organic material made from plants and animals‚ contains stored energy from the sun. Biomass in the form of bio fuels can be used to make the same products

value products. Diatoms are a group of eukaryotic‚ unicellular microorganisms generally characterized by an exterior cell wall comprised of amorphous silica (Falciatore & Bowler‚ 2002). Diatoms constitute a large proportion of phytoplanktonic algae and are of high ecological relevance‚ as they are believed to be responsible for approximately 40% of marine primary productivity (Falciatore & Bowler‚ 2002; Young & Beardell‚ 2005). Over the past few decades numerous species of diatoms have

detergents and household fertilizers has caused an excess of algae around the south shore. From the data and graphs presented to me on pages 2‚ 3‚ and 4‚ I believe the algae accumulation in the lake is the cause of the dead fish. It could be because the algae are using up vital oxygen sources that the fish need to survive. Table A on page 3 shows the amount of dead fish increase as the number of algae cells increase. This shows that the algae and fish are competing for oxygen‚ and the fish are losing
