OUR TECHNOLOGY

NULIFE’s solution is a 2nd generation, non-sulfided sustainable catalyst that effectives removes renewable fuels largest impurity – Oxygen!    

Our product replaces one of the existing catalysts already used in commercial hydrotreater units - therefore simplifying adoption. 

​

NULIFE uses diverted landfill waste to create our proprietary carbon carrier which emits up to 95% less GHG emissions when compared to traditional hydrotreating carriers (mined y-alumina).  

Our solution is created with 78% less mined materials vs traditional hydrotreating catalysts and uses no rare earth metals or exotic materials. 

​

WHY does NULIFE have so much interest in its 2nd gen catalyst?  Yes, it is made from landfill diverted waste; BUT the game-changing opportunity is to remove the need to add sulfur to the hydrotreating process.   

​

Renewable Fuel producers have to use catalysts that are modified from the fossil crude industry that naturally contains sulfur and very low levels of oxygen. Therefore, Renewable Fuel refiners must add sulfur to keep these catalysts active. 

​

Sulfided catalyst drawbacks:

​

Hydrotreaters are currently dominated by sulfided catalysts. It has long been recognized that to obtain maximum activity for NiMo/CoMo on alumina catalysts, they must be sulfided prior to use.  

Sulfiding comes with some key drawbacks: 

• Up to 2 days startup time focused on catalyst activation without fuel production.  

• Dimethyl disulfide (DMDS) is the most commonly used sulfur agent in this process.  

• The estimated cost to add sulfur and safely remove/dispose of hydrogen sulfide is over USD 37M/year for a 264 million gallon per year refinery. 

• You must also consider the effort, time and safety concerns of removing and disposing of the sulfur by-product: hydrogen sulfide. 

 
Renewable diesel feedstocks such as fats/oils/greases often contain extremely low levels of sulfur. The competition must continuously reactivate their catalyst by adding sulfur into the stream. 

Delivering value, 1 ton at a time.

• NULIFE delivers a drop in solution sold at industry standard rates. 

• A more active catalyst can deliver more profit and emissions reduction to a fuel producer 

• Activity, when combined with stability can result in lower start of run temperatures which is incredibly valuable to a refiner. 

• Removing the need for sulfide reduces costs while improving safety and environmental performance 

• NULIFE’s patent pending carbon carrier can be used for additional catalysts and applications
