Khosla Ventures and BIOeCON in joint venture to develop catalytic cracking of biomass into fuels
Khosla Ventures and BIOeCON announced today the formation of their joint venture KiOR Inc. Khosla Ventures will provide the Series A funding whereas BIOeCON will bring its knowledge and intellectual property for its ‘Biomass Catalytic Cracking Process’ (BCC). KiOR Inc. will focus on the further development and commercialization of the BCC technology as well as prepare for raising significantly more capital in the next two to three years.
The key technical problem in the conversion of cellulosic biomass into usable fuels is how to open up the inaccessible solid fibrous lignocellulosic material, so that it can be effectively transformed. Most of the existing processes to unlock these woody structures are quite costly and intensive of energy or chemicals. BIOeCON has developed a simple non-energy intensive way to make the woody biomass accessible to catalysts and convert to a bio-oil product with significantly improved product properties compared to other thermochemical processes.
Current next-generation bioconversion techniques for the production of liquids from biomass show the following disadvantages:
Classic catalytic pyrolysis is a simple, effective process that does not require high capital costs but results in low product quality that is tarry, black, acid and shows relatively poor yields. The BCC process takes the advantages of this catalytic pyrolysis process with it, using existing proven technology elements for large scale production, but delivers a high product quality with a low acidity, high yields and a strong energy balance (schematic, click to enlarge).

The conversion of cellulosic biomass to bio-oil thus represents a significant commercial opportunity that also offers important benefits, including using post-harvesting waste; promoting environmental sustainability; reducing reliance on fossil fuels such as crude oil; and enabling economic development and job creation in rural areas.
KiOR’s concept and approach is unique and has the potential to become a large scale, widely applied technology, that can improve energy availability and sustainability to both the developed and developing world. The BCC technology unlocks the energy of vast amounts of biomass waste and converts it into a high valued energy product. This will not only reduce net carbon dioxide emission, but can also improve the energy independence of many countries.

Current next-generation bioconversion techniques for the production of liquids from biomass show the following disadvantages:
- Bio-catalytic (enzymatic) conversion, better known as cellulosic ethanol made via biochemical transformation: in this process, the fibrous cellulose is not easily ‘accessible’ to enzymes, requiring long conversion times (> 50 hours) and large reactor volumes (~10% solids); it presents a high cost of ethanol-water separation
- Gasification followed by gas-to-liquids (GTL): gasification of biomass is energy intensive because it requires high temperatures; GTL process is a complex, multi-step process and comes at a high cost
- Thermochemical cracking, known as fast-pyrolysis to yield bio-oil: the disadvantage is the fact that a poor quality product is obtained (bio-oil, pyrolysis oil) which requires costly post-treating

BIOeCON has a strong R&D network and solid scientific fundamentals. We have done a thorough evaluation of the technology and research programs and believe this can be a breakthrough technology. - Doug Cameron, Khosla Ventures’ Chief Scientific AdvisorWith the BCC technique, abundant lignocellulosic biomass - found in grass, wood, and various agricultural and forestry wastes - can be turned into a bio-oil product that can be further upgraded to a wide range of transportation fuels:
