Generation of H2 on Board Lng Vessels for Consumption in the Propulsion System

open access: yesPolish Maritime Research, 2020
At present, LNG vessels without reliquefaction plants consume the BOG (boil-off gas) in their engines and the excess is burned in the gas combustion unit without recovering any of its energy content.

A comprehensive evaluation of a novel integrated system consisting of hydrogen boil-off gas reliquifying process and polymer exchange membrane fuel cell using exergoeconomic and Markov analyses

open access: yesEnergy Reports, 2022
The price of constructing hydrogen generation units is very high and sometimes it is not possible to build them in the desired location, so the transfer of hydrogen from the hydrogen generation system to the units that need it is justified.

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

open access: yesAdvanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.

A new method for evaluating the heat leak of cryogenic vessels without exhaust gas

open access: yesHeliyon, 2023
The thermal insulation performance of cryogenic vessels is evaluated by the boil-off gas (BOG) rate and heat leak as a reference standard; however, it consumes considerable testing time and working medium.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Helium extraction and nitrogen removal from LNG boil-off gas

open access: yesIOP Conference Series: Materials Science and Engineering, 2017
The helium bearing boil off gas (BOG) from liquid natural gas (LNG) storage tank in LNG plant, which has a helium concentration of about 1%, has attracted the attention in China as a new helium source. As the BOG is usually reused by re-condensing to recover methane, it is likely to cause continuous accumulation of nitrogen in the unit, thus a nitrogen
