Eco-friendly Direct Conversion of Biogas into Liquid Fuels

A novel capsule catalyst, enhanced with unique core-shell structures, enables the one-step production of high-value-added liquid fuels from biogas using only one reactor. The resulting liquid fuel requires no further modification.

Technology overview

Liquid fuels derived from biogas show promise as a renewable and clean energy source. However, transforming biogas into a high-value liquid fuel equivalent to diesel or gasoline typically involves a costly two-step process. RP has developed novel enhanced capsule catalysts with unique core-shell structures, enabling the one-step production of high-value liquid fuels from biogas using only one reactor. These capsule catalysts directly convert syngas into liquid fuels, which have improved petrol-like qualities.

Technology features

The novel enhanced capsule catalysts have:

  • Dual functionalities that bring about gas-to-liquid reactions. They also enable catalytic cracking and isomerisation, thus achieving a one-step process.

  • Excellent durability and high surface area, enabling a higher yield of liquid fuel.

  • A robust mesoporous framework optimised for the conversion rate of the reaction.

  • High selectivity for shorter-chain or light hydrocarbon (C5-C10) and a high CO conversion, allowing biogas to be converted more efficiently into high-value liquid fuels within a shorter period.

Potential applications

  • Companies looking for renewable and clean energy through the gas-to-liquid (GTL) technology to diversify their energy sources.

  • Poultry farms

  • Food waste treatment plants

  • Wastewater treatment industries

Benefits

  • Liquid fuels can be used as diesel or gasoline substitutes without any modification to engines and existing refuelling facilities

  • Highly scalable

  • Reduce gas-to-liquid production costs as only one reactor is required

  • More efficient with a single-step process conversion to liquid fuel

Commercialisation

The technology is available for licensing and deployment.
