A small-size gasification unit is improved through process optimization to simulate industrial United Gas Improvement Company gasification. It finds that the reaction temperature has important impacts on semicoke catalyzed methane gas mixture. The addition of water vapor can enhance the catalytic activity of reforming, which is due to the fact that addition of water vapor not only removes carbo...

Abnormal growth of population and development enormously increases energy demand. In present scenario utilization of fossils fuels to meet this demand is not enough and also leads to pollution, global warming, climate change as well as natural disaster. Therefore, hydrogen as energy carrier is a major option on these prospects as it is non-polluting and renewable. The renewable hydrogen energy ...

This work describes two different configurations of syngas production processes using a combination of steam methane reforming (SMR) and dry reforming of methane (DRM). The ideal SMR+DRM process ensures the maximum product yield, the heat-integrated SMR+DRM process fulfills the maximum heat recovery, and the stand-alone SMR+DRM process effectively suppress net CO2 emissions. Through kinetic mod...

Steam methane reforming is a major method of hydrogen production. However, this usually suffers from low energy efficiency and high carbon-emission intensity. To solve issue, novel steam-methane-reforming process over Ni-based catalyst in pressurized dual fluidized bed reactor proposed work. A three-dimensional computational fluid dynamics (CFD) model for the complex physicochemical was built t...

The partial oxidation of methane to synthesis gas was investigated in a novel type of perm selective membrane reactor using Perowskite hollow fibers. The operating behaviour of this membrane reactor integrating the process steps selective separation of oxygen from air, selective O2 transfer in the membrane and oxidation of methane with simultaneous steam reforming was investigated theoretically...

Currently, hydrogen is mainly produced through steam reforming of natural gas. However, this conventional process involves environmental and energy security concerns. This has led to the development of alternative technologies for (potentially) green hydrogen production. In this work, the environmental and energy performance of biohydrogen produced in Europe via steam reforming of glycerol and ...

This chapter reviews recent studies of catalytic reforming of logistic fuels at hightemperature. Aside from steam and autothermal reforming, special consideration is given to partial oxidation conditions. Natural gas, gasoline, diesel, and ethanol containing fuels are discussed. Methane and iso-octane as fuel surrogates are exemplarily used to explain the behavior of the reformers in particular...

An experimental and kinetic modeling study on the Ni-catalyzed conversion of methane under oxidative and reforming conditions is presented. The numerical model is based on a surface reaction mechanism consisting of 52 elementary-step like reactions with 14 surface and six gas-phase species. Reactions for the conversion of methane with oxygen, steam, and CO2 as well as methanation, water-gas shi...
