Accelerative Effect of Carbon Nanotubes and Lecithin Coupled with Loofah Matrix on the Kinetics of Methane Hydrate Formation

Energy & Fuels, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 14, 2025

Methane hydrate (MH) has attracted considerable attention as a safe and efficient method for storing transporting natural gas. Its rapid formation high storage capacity are key factors in gas transportation technology. Given this background, study aimed to improve the kinetics of MH investigated synergistic effect carbon nanotubes (MCNTs) lecithin (PC) loofah supports promote MH. It was found that induction time shortened by 92.40 94.30% when concentration MCNTs dynamic system increased from 0.005 0.025 wt % compared pure water system, maximum could reach up 142.83 V/V, with 0.015 having greatest effect. On basis, static constructed coupling loofah, significantly accelerated 93.60%, 23.03% alone. Furthermore, introduction PC 50% promoted wall climbing growth MH, although impact on volume water-to-hydrate conversion rate smaller. Finally, based enhancement efficiency cost-effectiveness evaluation, we coupled MCNTs, PC, excellently economically green. This offers an efficient, economical, environmentally friendly new approach methane transport

Study on the Promotion of Gas Hydrate Generation by Three Different Electric Field Waveform Signals in Synergy with Surfactants

The Journal of Physical Chemistry B, Journal Year: 2025, Volume and Issue: unknown

Published: April 4, 2025

The rapid development of the natural gas hydrate industry has put forward higher requirements for promotion technology. exploration methods that can simultaneously enhance both formation rate and final water conversion efficiency become a critical research focus. This study systematically investigated synergistic effects electric field (EF) signals, including three distinct waveforms (square, sine, ramp wave) at six different voltage levels, combined with four concentration gradients cationic surfactant called hexadecyl trimethylammonium bromide (CTAB) on CH4 process. Experimental results demonstrated application external EF significantly enhanced storage capacity hydrate, exhibiting varying degrees promotional effects. Notably, square wave wave, which allow instantaneous changes in direction, exhibited superior performance improving rates enhancing fluidity. Furthermore, kinetic model was developed, showed excellent agreement observed results. These findings not only advance theoretical framework EF-assisted but also provide valuable insights practical guidance technologies.
