Advanced Brayton-Cycle-Based Zero-Emission Power Plants Burning Fossil Fuels

A promising means of reducing emissions from power plants burning fossil fuels is a Brayton-cycle-based semi-closed O2/CO2 cycle, with or without a bottoming Rankine cycle (zero-emission plant). Carleton University, in collaboration with the sponsor of this project, CANMET Energy Technology Centre (CETC), has been studying such a cycle.

Feasibility of integration of membrane reactor with gasification for clean coal application

R&D program on integration of membrane reactor with gasification under the umbrella of T&I (TIA3.42) was initiated about three years ago. This project met success as the concept of a membrane reactor application has been proven on a laboratory scale. It was verified that with a commercial WGSR catalyst up to 80% of H2 produced was removed through the membrane giving a high purity, nearly fuel cell grade H2 stream and also a clean stream of CO2 sequestration ready. Increase of up to 10% in CO conversion was achieved in a membrane reactor comparing to a conventional reactor for a feed stream from a gasifier.

This project enables commercial viability of Integrated Gasification Combined Cycle (IGGCC) scheme by combining gasification and membrane reactor technologies for clean hydrogen production with zero CO2 emissions. The expected significant process simplification and intensification capitalizes on a new industrial paradigm offered by membrane reactors that allows combining reaction and separation in one step. Effectively the products of gasification of low-cost opportunity feedstocks such as heavy residue or oils, pet coke or coal could be converted in a membrane assisted one step Water Gas Shift Reaction (WGSR) process to clean hydrogen and clean CO2 sequestration ready. CanmetENERGY has initiated an R&D program on membrane reactor assisted catalytic WGSR process and is teaming up with NCUT and Technip KTI to collaborate on this R&D initiative.

It is proposed to bring this process closer to a commercial scale by initiation of a second phase of this R&D project. An improvement of hydrothermal stability of the ceramic hydrogen permselective membrane by morphology adjustment will be further pursued. Also a research program allowing hydrogen membrane regeneration will be activated. These state of the art membranes will be utilized for R&D on a new multi-element membrane reactor suitable for operation at an elevated pressure to meet the requirements of a commercial gasifier. Modeling of the process will be implemented to achieve optimal operation. By the end of a three year R&D program it is expected that a pilot scale membrane based IGCC facility will be constructed and tested with our Industrial partners.

Zero Emissions Hydrogen Production via Gasification (ZEHP)

The objective of the project is to develop a process with the following attributes:

  1. A product fuel gas stream consisting of greater than 95% pure hydrogen suitable for oil sands upgrading and for use in fuel cells. Particulate and alkali concentrations in this stream will be reduced to such an extent that the stream will be suitable for feed to fuel cells, gas turbines, and membrane separation processes.
  2. A product gas stream consisting of greater than 95% pure CO2 with CO2 capture greater than 90%, suitable for sequestration.
  3. A product solids stream suitable for feeding to a cement kiln. The product stream will consist of calcium species, coal ash, and additional mineral species.
  4. Ability to process a variety of Canadian solid and liquid fuels including coal (high & low rank), petroleum coke, bitumen, and liquid resid.
  5. Near-zero airborne emissions.
  6. In-situ monitoring of H2, CO, CO2, H2O, and CH4 within the gasifier reactor.

The technology is expected to be able to supply very large volumes of hydrogen for oil sands upgrading, for electrical power production, and for the transportation sector with no CO2 emissions in the 2015 to 2030 time frame.
