Embodiment 1

[0049] Fabrication of photobioreactor devices at laboratory scale. Experiment to determine its effectiveness. The housing 1 of the photobioreactor device is a tube of transparent plastic. The outer surface of the photobioreactor is covered with a dark film impermeable to sunlight or artificial light (mainly in laboratories). The membrane can be removed to observe the condition of the capsule and the situation inside the housing 1 of the photobioreactor device. The internal dimensions of the housing 1 of the photobioreactor device are respectively: a diameter of 30mm and a height of 1000mm. A support grid 2 with a mesh diameter of 5 mm is arranged at a height of 50 mm above the lower base of the housing 1 of the photobioreactor device. The lower base of the enclosure is immersed in a capacity of 1dm 3 15mm below the water surface of the tank 16, excess water flows out from the tank 16 through the pipe 22 to a capacity of 1dm 3 The second collecting empty device, that is, o...

Embodiment 2

[0055] The housing 1 of the device consists of four side walls, a flat overhead protection and a flat floor inclined at 2% towards the outflow opening. The height of the device housing corresponding to the internal dimensions from the bottom plate to the overhead protection is 5.1 m, and the internal dimensions in cross-section are respectively: length 2.5 m, width 1.0 m. The three vertical walls are transparent vacuum insulated 3mm glass. The fourth wall is located on the north side. This is a steel wall made of acid resistant steel with thermally insulating expanded polystyrene of 80mm thickness. The vertical wall of the enclosure is divided equally horizontally into 20 sections each 0.2m high and into two end sections each 0.3m high, the upper end section ending with the overhead protection and the flat bottom section lower segment. Each of the 20 segments is an independent structural element consisting of an insulated side wall permanently connected to a plastic perfora...

Abstract

A photobioreactor for CO2 biosequestration according to the invention has a biomass of algae or cyanobacteria immobilised in capsules (3) which have an outer envelope (4). The capsules of the biomass of algae or cyanobacteria (3) are supplied with light from a light source (6) by a separate, single light tube (5). In the photobioreactor, the capsules (3) are surrounded by a gaseous atmosphere and are wetted with a culture medium and periodically flushed. The photobioreactor is polyhedral or circular in its cross section.

Description

technical field [0001] The object of the present invention is to use fixed algal or cyanobacterial biomass for CO 2 Photobioreactor for biosequestration. Background technique [0002] Phototrophic algae use energy from sunlight or artificial light to convert atmospheric CO through photosynthesis 2 Transformed into the organic compounds that make up its building materials. For photosynthesis to take place and algal biomass to be produced, adequate access to light and CO is required 2 . In addition, the pH and temperature of the cultivation, as well as the type of reactor, open or closed, are important parameters. [0003] Due to the global excess of CO 2 emissions to the atmosphere, and requires the analysis of CO from different sources 2 For enhanced and innovative storage in order to protect the human living environment and prevent the greenhouse effect, there has been continuous research on the use of CO 2 An effective method of incorporation into biomass to maintai...
