Biodiesel – utilizing waste agrarian items to power school transports Part 1 - Synthesis Presented to CONASTA 59 2010 by the Primary Industry Center for Science Education (PICSE) Dr Robert Elliott (Dr) David Schaller – Macquarie Oils Ms Anna Paice - UTAS

Slide 2

What is PICSE? Essential Industry Center for Science Education based at UTAS National system 8 Activity Centers Attracting gifted understudies to study science, experiencing real aptitudes deficiencies Teacher PDs, class visits, Industry Placement Scholarship for yr 11/12, Science Camps yr 10, classroom assets, Science Investigation Awards yr 5-12

Slide 3

Industry Placement Scholarship

Slide 4

Learning Outcomes Make atmosphere face off regarding concrete Understand carbon nonpartisan fuel Understand why BD (not straight veg oil) Chemistry: fats, cleanser and biodiesel Poor BD union - prompts examination, experimentation, improvement

Slide 5

Connections to educational modules Renewable fills Titration – corrosive/base Saponification response Organic mixes – naming Esterification response Factors affecting response rates, consummation/balance Experimental plan and process

Slide 7

Driving far and wide on straight vegetable oil (SVO) (Biodiesel instruction venture: Oil+Water - > http://www.naturalheroes.tv/vod.html ) http://susty.com/picture/drive10.jpg http://nrpw.com/rig.html

Slide 8

Ignition by pressure: no sparkle plug in diesels http://www.youtube.com/watch?v=LcQcfoanCU0&feature=related

Slide 9

High consistency of straight vegetable oil (SVO) http://bobbybilt-rhino.tripod.com/http://sciencesquad.questacon.edu.au/exercises/falling_marbles.html

Slide 10

Biodiesel versus vegetable oil (SVO) Viscosity - > fine splash Demo

Slide 13

Biodiesel versus vegetable oil (SVO) Flammability (streak point) Whoosh!

Slide 14

Converting fats to biodiesel glycerol TG (Fat) DG MG +

Slide 15

Safety Biodiesel is non-dangerous, however... making biodiesel... Combustible – liquor Toxic-methanol Corrosive – burning pop Heat/flashes... Picture from http://www.odec.ca/ventures/2006/bach6k2/discuss.htm

Slide 16

Ethanol-based biodiesel demos? The first Dr Pepper methanol convention Existing little scale ethanol-based lesson Our adjustment of the Dr. Pepper convention to ethanol http://www.biodieselcommunity.org/http://attra.ncat.org/attra-bar/biodiesel.html#making Or Small scale ethanol ref

Slide 17

+ H 2 + H 2 O + liquor Margarine + H 2 Soap (FFAs) Biodiesel (FAMEs) Alkanes

Slide 18

Dry liquor, dry NaOH, dry/new oil: <1% FFAs, dry crystal, dry air Soap + H 2 O + oil + shaking = ??? Have you ever attempted to blaze cleanser? Reward: why doesn't cleanser blaze?

Slide 19

Making the impetus with channel cleaner + http://www.northcoastchemicals.com.au/inventory/pictures/0210-2-shU1.JPG

Slide 20

Progress of the transesterification response

Slide 21

Burning glycerol makes a sticky wreckage you don't need in your motor! http://www.impactlab.com/2008/08/14/marshmallow-tumor/http://jumboempanadas.blogspot.com/2006/10/how-hard-would it be able to be-to-make-fluffy.html

Slide 22

'Pre-wash' helps glycerol separate + 1 Tbs H 2 O 100 ml + 20ml = around 150 ml

Slide 23

Washing with salt water † to evacuate debases: NaOH, ethanol, cleanser

Slide 24

Modifications to the Dr Pepper demo convention Use less dangerous ethanol Dry ethanol utilizing polenta (or rock salt)(Optional?) Longer response times (heat?) Trigger glycerol detachment with H 2 O prewash Prevent emulsions with salt washes http://attra.ncat.org/attra-bar/biodiesel.html#making Or Small scale ethanol ref http://www.biodieselcommunity.org/

Slide 25

Bob Elliott's Biodiesel Protocol Add 30g NaOH to 200mL dry ethanol >95% in a tapered cup, blend well. Utilize a hotplate to break up impetus in the liquor if required. Utilize a vacant, totally dry 1.25L soda pop jug or 1L isolating pipe. Include 300mL of new vegetable oil (canola, soy bean, olive, poppy, almond and so forth) then include the disintegrated catalyst+alcohol blend. Delicately shake by modifying jug or pipe a few times and leave to settle overnight, or think about various response times eg 5 mins, 10 mins, 20 mins, 30 mins. Wash the biodiesel
