“…More details about the set up and tests were described elsewhere [27]. The tests were performed at medium (750-900°C) and high temperature (900-1050°C) using the producer gas from the gasification Wood A, Wood B, Miscanthus at 0.35 and 0.75 ms.…”

“…Some of us previously studied the impact of the main contaminants of the producer gas on a Ni/MgAl 2 O 4 reforming catalyst in a laboratory environment and after exposure to the raw syngas from a downdraft gasifier [26]. Moreover, a similar catalyst was tested in the reforming of the producer gas of an oxygen/steam CFB gasifier, showing that the catalytic activity was related to the composition of the biomass [27]. In the present work, the deactivation mechanisms of the commercial-like Ni-based reforming catalyst were elucidated.…”

“…The CHRISGAS Project was based on the Värnamo Biomass Gasification Centre (VBGCC) in Sweden, a 18 MWth pressurised circulating fluidized bed (CFB) system [25] to be completed by a hot gas filtration system and gas conditioning taking into account the experience and knowledge acquired in the project. The upgrading of the producer gas was planned to be performed by autothermal reforming and water gas shift and some studies were carried out to select the best catalysts [26][27][28][29][30]. These technologies are well established at an industrial scale [31] but the main challenge of their application in the upgrading of the gasification-generated gas is the development of catalysts active and stable in the presence of strong contaminants.…”

“…The information previously obtained was reviewed and completed by studying the effect of HCl in a laboratory scale, the thermal and hydrothermal sintering and the regeneration conditions. In addition, the catalyst was exposed to the raw gas coming from the oxygen/steam CFB gasification of the lignocellulosic fuels used in the reforming tests [27]: a clean wood made of saw dust (Wood A), a wood mainly constituted of bark and branches (Wood B), and an herbaceous biomass (Miscanthus). The content in ashes and sulphur is biomass dependent, the general trend is Wood A \ Wood B \ Miscanthus.…”

The deactivation of a nickel reforming catalyst during the upgrading of the producer gas obtained by gasification of lignocellulosic biomass was studied. The research involved several steps: the selective deactivation of the catalyst in a laboratory scale; the streaming of the catalyst with the producer gas of a downdraft and an oxygen/steam circulating fluidized bed (CFB) gasifier; and tests in a reformer placed in a slipstream of the CFB gasifier. The information obtained allowed to elucidate the catalyst deactivation mechanisms taking place during the reforming of the producer gas: physical deactivation by deposition of fine ashes, aerosol particulate or carbon; poisoning by H 2 S and HCl present in the gas phase and thermal sintering because of the high operation temperatures required to avoid the chemical deactivation. These physical and chemical effects depended on the composition of the biomass fuel.

Hydrogen fuelled polymer electrolyte fuel cells (PEFC) offer clear environmental benefits. Lack of viable hydrogen infrastructure in the near future means that a key issue is availability of hydrogen at the point of use. Liquefied petroleum gas (LPG) offers advantages as a fuel over other hydrocarbons because there is already an infrastructure in place for remote areas. Hydrogen supply via steam reforming of LPG is therefore a feasible avenue of achieving the environmental benefits. Commercial grade LPG unavoidably contain sulphur as an odorant, the sulphur needs to be removed from the fuel stream before it reaches the reformer catalyst and fuel cell. Utilizing sulphur tolerant catalysts in the reformer leads to a simpler fuel processor design. Thermal management and reforming efficiency has been a challenge for the sulphur tolerant catalysts. In this paper, a multi‐function compact micro‐channel reactor designed for hydrocarbon steam reforming was evaluated for use with LPG. A sulphur tolerant catalyst was wash‐coated on to the reforming layers. The reformer was tested over a wide range of reactor temperatures, steam to carbon ratios and fuel flow rates. Over 60% of H2 composition can be achieved at high reforming temperatures with a LPG supply rate of 0.75 dm3 min−1 (STP) and a S/C ratio of 4.
