Novel Surfactants For Carbon Dioxide In Oil Foams
03994
This technology employs a water-free hydraulic fracturing process where a CO2-in-oil foam is generated by mixing liquefied CO2 with an oil-surfactant solution.
- Enhanced oil recovery.
The process relies on silicone surfactants featuring dual hydrophobic segments that stabilize thin oil films between CO2 bubbles, creating a viscous and durable foam for effective proppant transport.

Catalyst for CO2 Hydrogenation and Fischer-Tropsch to Olefins Synthesis
04637
To address this, researchers have designed a nanocatalyst to promote CO2 hydrogenation and FTO synthesis, which offer a direct route to convert feedstock CO2 or syngas to light olefins without any intermediate steps.
This catalyst catalyzes direct CO2 hydrogenation to produce light olefins with up to 37% CO2 conversion and 65% light olefins in the hydrocarbon distribution.
University of Pittsburgh researchers have developed a highly efficient nanocatalyst that demonstrates significant activity for both CO2 hydrogenation and Fischer-Tropsch to Olefins (FTO) synthesis, with exceptional stability over extended reaction periods.
