A solution for Biodiesel production issues
Smart Catalyst does not react with Fatty Acids to make Soap. For this reason, the level of Fatty Acid in the feedstock should be below 0.25% in order for the Biodiesel to meet ASTM D6751 specification. This is not an issue when refined oils are used in Biodiesel manufacture. For the many processors of crude and waste oils this may not be a viable option. Ceimici Novel has developed both Smart Modifier and Smart Processing to deliver B100 of comparable specification and processing characteristics to those of refined oils.
Unlike Sodium Methylate Smart Catalyst is insoluble in Methanol ,Triglyceride and Methyl Ester. Smart Catalyst is soluble in Glycerol. While temperature and catalyst concentration are important for the rate of conversion the degree of agitation is the most significant consideration. While todays biodiesel production using Sodium Methylate centres around twin batch tank or continuous flow arrangements using 60 mins of processing time Smart Catalyst has the activity to complete the manufacture in <15mins in a single reaction stage.
Under standard processing conditions Smart Catalyst does not react with Fatty Acid nor does it catalyze the hydrolysis of triglyceride to Fatty Acid. Higher levels of moisture in the feedstocks can however slow down the transesterification process but in areas where this may arise such as the processing of waste oils this eventuality is comprehensively dealt with by using the Smart Modifier process. This condition will also be met where processors use Glycerolysis as a pretreatment for Fatty Acids.
The Glycerol produced as a coproduct of the Biodiesel process using Smart Catalyst is of low viscosity, light in color and does not require storage in heated tanks. Smart Catalyst used in the process resides in the Glycerol at purity levels up to 95%.
The separation of the Glycerol-Biodiesel is fast <20mins and precise. There is no emulsion interface or rag layers. The need for centrifugal separation is unnecessary.
The Glycerol generated by this process will be purchased by Ceimici Novel.
By using Smart Catalyst the processor will reach ASTM D6751 on time every time. Tough specifications such as cold soak and monoglyceride levels are easily attained and exceeded. Down stream bottlenecks such as separation are history and the ability to increase production capacity a reality.
