Bio-gasoline
One-step Biobased Green Gasoline Production from Biodiesel Plant Waste Glycerol
This technology concerns a low cost, high performance, and high value biobased green gasoline biofuel (bio-gasoline) production technology from biodiesel plant crude glycerol using a novel multifunctional heterogeneous catalyst integrated with an advanced reactor. The glycerol is directly converted to bio-gasoline without the use of any solvents, hydrogen, or other reactants. The bio-gasoline is used as a replacement for petroleum based gasoline or blended with petroleum gasoline. The estimated production costs of the bio-gasoline are significantly less than the price of petroleum gasoline while its energy density is higher than that of petroleum gasoline.
Crude glycerol samples from different biodiesel plants were evaluated, and the effects of glycerol impurities on the catalytic performance were studied. The bio-gasoline fuel properties, including energy density, octane number, copper corrosion, sulfur content, kinematic viscosity, and flash point, were evaluated.
Biogas to Drop-in Biofuel
Atom-efficient Transformation of Biogas for Drop-in Biofuel Production
This KEW technology aims to develop a transformative atomic-scale low-cost Rh-based catalyst for highly energy efficient and atom-economical biogas conversion with no coke formation or sintering through CO2 dry reforming of methane using biogas as the feedstock, followed by the Fischer-Tropsch process to produce a drop-in biofuel. Dry reforming of methane with CO2 is one of most promising routes for co-utilization of methane and CO2, two greenhouse gases, to produce valuable chemical building blocks, hydrogen and CO, for biofuel production. Unfortunately, after decades of efforts and numerous studies in industry and academia, there are no cost-effective commercial processes yet. The key challenge is the catalyst. Two types of catalysts have been extensively studied: noble metal based catalysts and Ni based catalysts. The noble metal catalysts are active and relatively stable. However, these catalysts are too costly for commercial applications. Despite the abundance of Ni and its low cost and high activity, Ni-based catalysts suffer heavily from rapid deactivation due to coke deposition on the active sites and sintering of the metallic particles.
Biodiesel
KEW develop a Heterogeneous Catalyst significantly reduced the cost of the production of biodiesel and it effectively converts the cooking oils to biodiesel with high yields. Biodiesel is a renewable and clean form of energy produced from biomass materials. The production and use of biodiesel will improve air quality, promote economic development, and enhance local energy independence. However, the traditional way for producing the biodiesel makes the high price and installs a hurdle in the marketplace for distributors and consumers.

Sugar Catalysis
This technology concerns an energy efficient, cost effective, and environmentally friendly fixed-bed process for the production of the low cost high value renewable products 5-hydroxymethylfurfural (HMF) and furfural from a biomass hydrolyzed aqueous sugar solution. The commercial success of this technology will bring unprecedented opportunities to biomass based materials production and applications.
