This invention discloses a device for regulating oxygen content in a photophytic aquatic body, comprising a culture tube equipped with a light source assembly, a pneumatic piston assembly at the bottom of the culture tube including a dual-function air pump for charging and suction, and a piston plate slidably disposed inside the culture tube; an air box at the top of the culture tube, equipped with a carbon dioxide introduction mechanism and an oxygen removal mechanism. The piston plate reciprocates to circulate the algal solution, facilitating the transfer of oxygen produced by microalgae photosynthesis into the air box. When the oxygen concentration in the air box exceeds a set value, the piston plate automatically accelerates its movement. This accelerated movement of the piston plate also triggers the oxygen removal mechanism to expel the oxygen produced in the air box more quickly, thus regulating the oxygen content and preventing excessive oxygen consumption and carbon dioxide production caused by excessively high oxygen-to-gas mixture concentrations in the air box.

The invention relates to a zero-emission technology for producing power in a thermal plant using natural gas (NG) or liquefied natural gas (LNG), followed by capturing carbon dioxide (CO₂) and converting it into green Dimethyl Ether (DME). The process integrates a gas-based combined cycle power plant with CO₂ capture through Pressure Swing Adsorption (PSA) (106) and Monoethanolamine (MEA) purification. Captured CO₂ undergoes a Reverse Water Gas Shift (RWGS) (306) reaction at temperatures above 900°C to form CO, which, along with syngas from steam methane reforming (308a, 308) at 525°C to 900°C and 25 ATA pressure, is converted into DME using a Cu / ZnO / Al₂O₃ catalyst at 250-300°C and 25-40 ATA. The process achieves an energy efficiency factor of 93.04%, producing 92 kg of DME per 48 kg of LNG, with a 94% greenhouse gas abatement, contributing to net-zero emissions (NZE) while generating bulk thermal power.
