DA COSTA ÊAbstract Ê ÊÊÊÊÊÊÊÊÊÊÊ The aim of this study was to develop a new process for the synthesis of polyglycerols from crude glycerin. Glycerin is the main by-product of the "BiodieselØ" process and therefore a cheap and in big quantities available raw material. ÊÊÊÊÊÊÊÊÊÊÊ Three different qualities of crude glycerin are available on the market (basic, sulphuric and chlorhydric glycerins) from the two French "DIESTERØ" units in ROUEN and in COMPIEGNE. >From sulphuric glycerin, the polyglycerols obtained contains a very low concentration of soluble salts. Besides, it causes no corrosion problems like chlorhydric glycerin. The nature of the soluble salts in glycerin determines the polyglycerol distributions and the mixtures obtained have different compositions compared with the commercial products. The basic glycerin contains big amounts of sodium soaps and yields polyglycerols with 25% (by weight) of cyclic compounds. Thus, sulphuric glycerin is certainly the best raw material. The polycondensation of sulphuric glycerin is carried out in presence of sodium sulphate (5% max) with sodium hydroxide within a temperature range of 250 to 265¿CØ. Conversion rates are determined by measuring the quantity of water which is produced during the reaction. For example, the synthesis of theoretical decaglycerol would lead to a weight loss of 18% by generation of water. For decaglycerol production a theoretical yield of 86.9% (by weight) has been determined. A yield of 79.4% was obtained during the industrial test. Different compositions of polyglycerols can be obtained with different degrees of polycondensation. ÊÊÊÊÊÊÊÊÊÊÊ The first step of the downstream process is a filtration which partly removes the residual salts. The removal of the remaining salts by ion exchange resins improves as well the colour of the product. ÊÊÊÊÊÊÊÊÊÊÊ Polyglycerol esters can be obtained by addition of fatty acids or methyl esters at 190¿C - 220¿C to the crude mixture which still contains the catalyst. In this case, the salts can be removed after the neutralisation of the basic catalyst. Ê Estimated cost of polyglycerols are depending on the price of crude glycerin and the capacity of the unit. The manufacturing costs of crude polyglycerols (without purification by ion exchange resins) decrease from 16 to 10FØ/kg if the annual productions increase from 100Øt/a to 500Øt/a. For information, market price varies between 15 and 32F/kg depending of the purity and the composition of the product. Ê Polyglycerols in the ester forms, are good emulsifying agents. Their main uses concern food industry and cosmetics. -----Original Message----- From: goat industries [ HYPERLINK "mailto:[EMAIL PROTECTED]"mailto:[EMAIL PROTECTED] o.uk] Sent: Thursday, May 30, 2002 12:38 PM To: biofuel@yahoogroups.com Subject: [biofuel] glycerin use I reply to: I am a member of this group since 2000, but I had no quastion until now. I have a big problem what to do with glycerin. I am pripare to buy a expensive (cca.60.000,00 $) vakum destilater to puryfai (clean) glycerin, but do not now for what use is than that glycerin. I make glycerinÊ from waste wegetable oil. Please help me! Thanks egon As with a lot of info on the net, there seems to be a lot of contradictions. Glycerin has been said to be a valuable biproduct, but retails at £750.00 per tonne (GBP) ex Albion chemicals, UK, which is not that fantastic for the producer. Other possibilities discussed have been for fertiliser (not a good option for myself) or as a furnace fuel for heating oil for drying or getting to reaction temperature. Nobody seems to have come forward with a good design for the furnace, which would involve preheating the fuel to about 500 degrees C to get a clean burn, but I peronnally think this is the best option and intend to persue this avenue. My stock pile of glycerine are beginning to become a problem and i don't want to dump it as waste. [Non-text portions of this message have been removed] --- Outgoing mail is certified Virus Free.
