Solid Catalyst Transesterification – 2

The Process of Transesterification Through Solid Catalyst Technology

SRS’ Solid Catalyst Transesterification Process efficiently converts feedstocks to Biodiesel with 99.8% yields or higher with no acids, sodium/potassium methylate or sulfuric acid required.

A 2 stage process involves the use of enzymes based solid catalyst that is capable of completing transesterification and converts 99.9% of triglycerides.

Unmatched Feedstock Flexibility

SRS’ cutting-edge biodiesel conversion processor gives producers the freedom to choose from a wide variety of feedstocks. You can easily switch between different raw materials—such as animal fats, vegetable oils, or used cooking oils—without interrupting or reducing production efficiency. This flexibility allows biodiesel producers to respond quickly to changes in market pricing and feedstock availability, giving them a competitive advantage in a constantly shifting industry.

Moreover, our system allows the blending of high free fatty acid (FFA) feedstocks with low FFA alternatives. This means producers are not locked into expensive, refined oils. Instead, they can lower raw material costs while maintaining optimal throughput and performance. SRS technology turns feedstock variability into an asset, not a limitation.

Complete and Efficient Conversion Process
Unlike traditional methods, SRS’ processor ensures full conversion of all glycerides into high-quality biodiesel. The system processes mono-, di-, and tri-glycerides through a highly optimized two-stage reaction system. This design not only guarantees complete transesterification but also minimizes the presence of unreacted oil or intermediate byproducts. The result is a cleaner, more consistent biodiesel product.

The two-stage process enhances overall yield, allowing producers to extract the maximum amount of fuel from their feedstock. As a result, there’s minimal waste and a more sustainable operation. Each molecule of oil is transformed into usable biodiesel, ensuring high process efficiency and product quality.

Premium Biodiesel That Exceeds Global Standards

Biodiesel produced using SRS’ system meets and often exceeds the strict quality benchmarks of ASTM D6751 and EN 14214 standards. With our advanced technology, you can expect a fuel that features improved combustion, reduced emissions, and superior engine compatibility.

SRS biodiesel offers lower viscosity, which means better flow characteristics and easier handling. At the same time, it delivers a higher cetane number, resulting in more power during combustion, quicker ignition, and improved fuel efficiency. These quality markers ensure cleaner engine performance and a longer engine life. Our process delivers a product that performs better, burns cleaner, and reduces your carbon footprint.

High-Purity Glycerin as a Valuable Co-Product

One major advantage of the SRS biodiesel processor is its ability to produce high-quality glycerin as a valuable byproduct. The system consistently yields industrial-grade glycerin with purity levels reaching up to 90%, depending on the feedstock used.

Rather than being treated as waste, this glycerin can be monetized for use in other industries such as cosmetics, pharmaceuticals, and chemical manufacturing. By adding this revenue stream, SRS helps you improve the economics of your biodiesel operation while supporting a more circular production model.

Reduced Operating Costs and Energy Use

SRS’ biodiesel conversion processor was designed with energy efficiency in mind. Thanks to its optimized thermal and reaction design, the cost to operate the system is extremely low. In fact, the estimated cost to run the reactor is less than one cent per gallon of biodiesel produced.

This low energy requirement translates into real savings, especially at higher production volumes. More importantly, it reflects a reduced carbon footprint, supporting the environmental goals of your biodiesel facility. In addition to energy efficiency, the system minimizes downtime and maintenance requirements, allowing for more continuous and stable operation.
