Combining the Heatpipe Reformer technology with hydrogen-intensified methanation for production of synthetic natural gas

Hydrogen from wood gasification with CCS – a techno-environmental analysis of production and use as transport fuel

“…The HPR technology selected is the one developed primarily at TU Munich, Germany, and continuous operation has been demonstrated at a scale of 500 kW, while the integration of this gasifier in a synthetic natural gas chain has been demonstrated at a scale of 100 kW at the Chair of Energy Process Engineering at FAU Erlangen-Nuremberg, Germany. 21,22 The HPR gasifier is an indirectly heated gasifier that consists of two separated fluidized beds: the gasification reactor and the combustion reactor (see Figure 2a). Wood is gasified with steam in the gasifier, which is operated at high pressure (feasible upper limit 10 bar).…”

“…For the HPR we assume that 33 % of the total biomass input is combusted in the combustion chamber. [21][22][23] While for the oxySER we assume that 63 mol% of the carbon present in the biomass is burnt in the combustor. 36,37 The amount of steam needed as reactant is subtracted by the amount of process steam co-produced; whereas the remaining process steam is expanded in the turbine section.…”

Renewable Hydrogen Production Processes for the Off-Gas Valorization in Integrated Steelworks through Hydrogen Intensified Methane and Methanol Syntheses

“…Therefore, many recent studies and projects are studying the possibility of improving this technology or simplifying the process itself to make it competitive. For instance, Neubert et al in [68] proposes a new catalytic methanation reactor with heat pipe integration into a structured reactor, that can be considered suitable alternatives to classical reactors for CO 2 methanation due its efficient temperature control; Leimert et al in [69] suggests the combination of heat pipe reformer biomass gasification process with hydrogen intensified methanation. Further studies on the production of methane from biomass are reported in [70][71][72], as well as from COG in [73].…”

“…Thus, any additional input hydrogen is not consumed in the process and remains unexploited in the product gases [75]. Table 2 shows the reaction equations for the methane and methanol syntheses from CO and CO 2 [69,76]. [69,76].…”
