As shown in Fig. 1, the production of biodiesel decreases as a function of catalyst concentration with the highest yield observed at NaOH concentration of 0.13 g and the lowest at 0.18 g.The concentration of catalyst can affect the yield of biodiesel. The most commonly used catalyst for biodiesel productions can be a base catalyst (KOH, NaOH) or Acidic catalyst (H 2 SO 4) Sodium hydroxide (Na OH), also known as lye or caustic soda, is a caustic metallic base. An alkali, caustic soda is widely used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, and detergents. Worldwide production in 1998 was around 45 million tonnes. Sodium hydroxide is also the most common base used in chemical laboratories. 20 g of NaOH dissolved in 1000 ml water = 0.5 N NaOH.

Production and applications of hydrogen. The most important industrial method for the production of hydrogen is the catalytic steam-hydrocarbon process, in which gaseous or vaporized hydrocarbons are treated with steam at high pressure over a nickel catalyst at 650°-950° C to produce carbon oxides and hydrogen: C n H 2n+2 + nH 2 O → nCO + (2n + 1)H 2; C n H 2n+2 + 2nH 2 O→ nCO 2. The results indicated that H 2 production was enhanced in the presence of NaOH when phenol supercritical water oxidation was controlled at a lower O/C ratio. Compared with the individual catalytic partial oxidation of phenol, the reaction with NaOH and H 2 O 2 simultaneously enhanced H 2 production and inhibited polycyclic polymer generation at O/C ratios below 0.5 in the NaOH(aq) system Maria Gunnarsson Department of Chemistry and Chemical Engineering CHALMERS UNIVERSITY OF TECHNOLOGY ABSTRACT Cellulose derived from wood can be used as raw material for production of textile fibres, making it a renewable alternative to fossil oil.
