Parabolic Photoreactor Layout for Higher Light Usage

The patent combines the light collection function and reaction vessel function into a single integrated structure. The parabolic trough collector serves simultaneously as the light collecting element and the reaction chamber, eliminating the need for separate light collection optics and reaction vessels. This merging increases the reactor area to light collection area ratio and improves light usage efficiency by directing concentrated light directly onto the reaction mixture within the same structure.

The patent transitions from a conventional planar reactor configuration to a three-dimensional parabolic trough structure. By utilizing the focal property of the parabolic geometry, light is concentrated along a linear focal line where the reaction mixture flows, enabling high productivity within a compact footprint. This dimensional approach allows the reaction zone to be positioned precisely at the focus where light intensity is maximized, increasing production per unit area.

The patent designs the parabolic trough reactor to be universally compatible with multiple light sources. The open-top configuration allows direct coupling with solar panels, while the same geometry can accommodate artificial light sources such as LEDs or lamps positioned at the focal line. This multi-functional design enables the reactor to adapt to different light sources without requiring fundamental design changes, simplifying the system while maintaining versatility.
