Magnidon+ removes both soaps and sterol glucosides from biodiesel

Recently Environ Fuels of New Zealand succesfully applied Magnidon+, Biodys activated bleaching earth compound, for biodiesel purification. Magnidon+ did not only prove to remove soaps and neutralize catalyst succesfully, but also removed the feared sterol glucosides which lead to high FBT levels. Environ Fuels has been using magnesiumsilicate and diatomite to achieve both removal of soaps and glucosides in the recent past, but decided to retire both these products in favor of Magnidon+ last month.

Sterol glucosides (SG’s) are present in some vegetable oils. They are not soluble in water and cannot be removed easily by traditional methods like filtration or centrifugation. The presence of SG in biodiesel may cause filter blockage at temperatures above the cloud point. Cold temperatures are likely to exacerbate the negative impact of the presence of SG in both pure biodiesel and biodiesel blends.

Two books on biodiesel

Looking to start with biodiesel production, small or big? Biodys would like to recommmend two books on the subject: The Secrets of Biodiesel and The Book on Biodiesel Both books by Mervyn Rees are avaialble from Amazon. If you have bought one of these books and you decide to buy a C300 biodiesel processor from Biodys, we will give you a EUR 50,00 discount on your purchase.

New low pricing for ion exchange resins

Biodys announces the immediate price reduction for Tulsion® T45 BD ion exchange resin for biodiesel purification. The resin will be available as per direct for EUR 3,98/kg ex works The Netherlands. Additionally Tulsion® T 45 BD MP (macroporous) resin is available for EUR 6,90/kg ex works. For companies using wet resins for biodiesel purification we have available Tulsion® T 42H strong wet cationic resin for EUR 1,36/liter.
Minimum volumes apply. Prices subject to change without prior notice. For more information please contact us per e-mail.

In the purification step, the above resins are used to remove trace levels of glycerin and soaps from the biodiesel exhibiting high conversion with excellent physical, chemical stability and operating characteristics. These resins can be used in wide range of temperature and pH conditions.

Zeppelin continuous separator update

Biodys now offers kits to convert horizontal ‘cigar’ shaped tanks into continuous biodiesel/glycerol or oil/water separators. Moving from batch based biodiesel production to continuous production almost always leads to a problem in the separation phase. Either separation is non-continuous as with batch, or it requires an expensive centrifuge system.

With Zeppelin technology, biodiesel producers can use any horizontal shaped tank as a continuous separator.

Thanks to a unique interface detection, the Zeppelin system allows an unattended low cost continuous separation. The interface between light and heavy phase is kept on a constant level. The Zeppelin system uses only a fraction of the energy required by centrifuges. It can be installed in most explosion proof environments where centrifuges are not allowed or are too expensive.

New solid catalyst for biodiesel available

Starting January 2010, Biodys offers a new esterification resin for the conversion of FFA’s into biodiesel (methylester). The resin acts as a non-miscible solid catalyst and is used in reactions where otherwise sulfuric or sulphonic acid is used.

T63MP is a catalyst grade strong acid cation exchange resin. It allows rapid diffusion of reactants into the beads by virtue of it’s specific pore size. The high surface area of the resin enables the accessibility of a large number of surface catalyst sites for reaction.
