Process yielding high value fuel additives (octane enhancers) from lignin
- 详细技术说明
- Efficient process for the depolymerization of lignin to produce substituted phenolic monomer compounds that are further converted to fuel additives
- *Abstract
-
BACKGROUNDFuel additives like octance enhancers have been traditionally derived from non-renewable petroleum products. Renewable sources are being explored as a source for producing fuel additives. A number of single step processes for depolymerization of lignin have been explored to date only with limited success. Existing two-step processes occur under harsher conditions (max reaction temperature can reach 420 - 900 ̊ C)
TECHNOLOGY DESCRIPTION
NCL scientists have developed an efficient 2 step process for depolymerization of lignin to substituted phenolic monomer compounds which could be further processed for use as high value fuels/additives. The process operates under milder reaction conditions (temperature range of 215- 250 ̊C). The reaction time is of 5 mins to 2 hrs. Product yield is >25%
MARKET POTENTIAL• US market for specialty fuel additives including octane enhancers has been predicted to grow 2.2percent annually to reach $1.2 billion in 2012.*
• Ethanol is a commonly used octane enhancer- its demand grew from about 1.2 billion gallons in 1997 to almost 5 billion gallons in 2006. *** http://www.reportlinker.com/p0100129-summary/US-Specialty-Fuel-Additives-Market.html (cited- 21/05/2012), **http://www.mendeley.com/research/supply-demand-elasticities-ethanol-fuel-market-20/ (cited- 21/05/2012)
VALUE/ADVANTAGES• Milder reactions due to the solid acid catalyst used- work under 270 ̊ C
• Process is more environmentally friendly than the conventional processes due to the recyclable catalysts
• Process results in very little loss of the products in the form of gas or due to degradation
APPLICATIONS• End products of the reaction can be used to produce high value fuel additives like octane enhancers
TECHNOLOGY STATUS• Demonstrated at the lab scale
• On the lookout for potential partners for spin-off and licensing
• Patents filed: IN# 2889DEL2010
