NEW FUELS TECHNOLOGY
A LIGNO-CELLULOSIC BIO-REFINERY PROCESS
Under license from ASTM approved North American renewable fuels technolgy companies, SACL is responsible for developing greenfield and/or brownfield conversion refinery opportunities within the ASEAN market. SACL license technology for the production of Ligno-Cellulosic Ethanol and Renewable Diesel additives. These products are then sold as intermediate feedstocks, suitable for further refining by existing refinery infrastructure providers, into modern sustainable fuel alternatives, such as, 2G-Ethanol, Renewable Diesel and Sustainable Aviation Fuel (SAF).
Our licenses provide access to patented technologies to make renewable fuels and chemicals from cellulosic material, such as Woodchip, Industrial Waste Timbers, Sugarcane Bagasse, Bamboo and/or Savannah Grasses.
The problem has always been that plants have evolved to protect their energy, starches and sugars, from microbial attack, by encapsulating their energy in an armour called Lignin. Until now, scientists have been trying to develop more and more exotic (and expensive) enzymes to destroy this Lignin armour, with limited commercial success, producing less than 190 Liters of useable fuel per Metric Tonne of cellulosic feedstock.
Our newer technologies, treat the biomass material diferently, by using a proprietary, low pressure, ambient temperature, chemical process. This pre-treatment, gently separates any cellulosic material into its three core components of Cellulose, Hemi Cellulose and Lignin. The resulting cellulose pulp is 99% pure and free of sugars and starches, residual lignin, metallic impurities and other contaminates, that often inhibit the efficiencies of existing enzymatic digestion processes. This resluts in a three fold increase in yield, approx. 570 litres of Bio-Ethanol per metric tonne of Pure Cellulose, using less energy input and low cost enzymes.
As a result, one metric tonne of refined cellulose pulp from woody biomass, can now be easily digested by inexpensive Gen 2 enzymes, enabling producers to use low cost, off-the-shelf production equipment to produce 2G-Ethanol. This ethanol can then be further refined into fuels such as A2J-SAF.
The separated pure Lignin is not wasted. The Lignin stream is captured and distilled out during the process. It is converted into a Biocrude, becoming a hydrotreated “ester”, an intermediate feedstock, that any existing petroleum oil refinery can co-process into valuable fuel products such as Renewable Diesel, Renewable Gasoline and SAF. This intermediate oil derivative, is basically a sulphur free, oxygenated, crude oil alternative feedstock, that can be converted into fuel by existing refinery infrastructure. Our process also captures the Biogenic CO₂ off-gases from the ethanol lines, to further enhance our carbon intensity score and generate additional revenues from the sale of biogenic CO₂ to the Food and Beverage industry.
