Magnesium Silicate
News Synthetic Magnesium Silicate with amorphous structure is mainly used for these applications: 1) Prolong or refresh frying cooking oil; 2) Dry wash of biodiesel; 3) to remove alkali metal catalyst residues in production process of polyether polyols or like these for systhesis of organic compound Visit Press Room

Dry Wash and Clean of Biodiesel using Synthetic Magnesium Silicate

Synthesis Magnesium Silicate is refered as synthetic, amorphous form of magnesium silicate, it is safe, pure fine white compound with porous internal structure and enormous activated surface, products are ideal for removal of polar chemicals including

biodiesel purifyingWater
EN ISO 12937 specifies a maximum of 500 ppm (parts per million) of water in biodiesel. As FAME is hygroscopic it can pick up water in storage and because of this there can be problems meeting the specification. At around 1500 ppm, the solubility limit is reached and the water becomes visible. Producers still using traditional “wet wash” systems may find this aspect of the EN Specification rather troublesome to achieve. Free water promotes biological growth and adverse reaction to transesterification which undoes biodiesel back into free fatty acids, which is disastrous in a fuel delivery system. Synthetic Magnesium Silicate provide DRY WASH.

Soaps
Synthetic magnesium silicate provide effective purification which removes residual soaps and metals which will lead to Carbon Residue.

Synthetic Magnesium Silicate contribute to reduction of Acid value which is a measure of free fatty acids contained in a fuel sample. The fewer residual compounds, the lower the acid value of the biodiesel. Effective purification using synthetic magnesium silicate will ensure that EN14104 is consistently achievable as is EN14214. Acid number will also increase over time if the biodiesel is stored incorrectly. Acid value can be determined rapidly using a TAN (Total Acid Number) drop test. A sample of biodiesel is added to a red coloured chemical reagent and then another chemical is added
until the colour changes to green. The number of drops taken is easily converted to the Acid Number of the fuel.

Glycerides
Glycerides and water have density higher, and it often sink into the bottom after settling. Both glyceride (other name like glycerin, magnesium silicate, oil filter powder, oil filter aid powder glycerol) and water are polar chemicals which can be got rid of. It is vitally important that a good transesterification reaction is achieved, as by achieving a transformation of more than 96.5% limits the amount of residual mono, di and triglycerides as
per EN14105. Failing to meet the specification implies low conversion to ester and deposit formation on injectors and valves.

Ester
To pass EN14103 there must be a minimum ester transformation of 96.5% FFA’s into Methyl Esters.

Alkali Metals
Both Sodium and Potassium are known as Alkali metals which are limited to a combined 5ppm maximum. Magnesium Silicate can provide effective purification processes enables the effective removal of residual traces of Sodium and Potassium which can lead to levels exceeding the 5mg/kg upper limit required by EN14109.

Phosphate
PO4 3- can be removed either it combine with K+ ion or not. That is what synthetic magnesium silicate is preferred to be used to remove polyols catalyst residues during production process of polyether polyols . Removal of production residues and chemicals to pass EN14107 and also across the specification of
standards which combine to meet EN14214.

Drying & polishing system of biodiesel, our magnesium silicate could be a easy and good choice, usage is less than 10-15kg per 1000liter of biodiesel.
