Utilization of carbon dioxide

The development of carbon dioxide utilization is related to the bottleneck issues in the advancement of coal chemical industry; people are also conducting explorations and research in this area, such as the combination of carbon with natural gas and the use of carbon dioxide to cultivate algae for the production of biodiesel. Please discuss the progress made in these areas. . Note # ) # # , .
We are also researching this, and it has been determined that it can be used on a large scale for EOR and coalbed methane extraction. The gas consumption for other purposes such as food production and greenhouses is too low
I’m not very familiar with it, but I’ve seen methods that use adsorption for collection
Large-scale utilization is practically impossible; the best approach is to reduce emissions. Other methods either involve temporary closures or result in greater emissions in an attempt to deal with some of the carbon dioxide, which is not worth it.
The large-scale utilization of CO2, especially for resource utilization, is still in the exploratory stage. It is primarily used in CO2 flooding in oil fields, CO2 flooding in coalbed methane fields, and the use of CO2 to cultivate microalgae for biofuel production; other applications are rare. The main approach remains emission reduction, and geologic sequestration of CO2 is also a topic of significant interest.
Capture and store it, then release it once an ice age arrives.
Just increase nuclear power generation; without fossil fuels, there will be no CO2 problem
Using CO2 to cultivate seaweed for biodiesel production is still a long way from industrialization, as research on seaweeds with high oil content has only just begun.
Microalgae use photosynthesis to convert carbon dioxide into oil, which is stored as oil droplets within the cells. Oil droplets can be converted into fatty acid methyl esters through transesterification, namely biodiesel. In October 2007, International Energy Corporation announced the development of a new technology for producing biofuels from microalgae ； In December, Shell announced the formation of a joint venture named Cellena with HR Biopetroleum, an American company involved in biofuel business, to invest $7 billion in research on microalgae biodiesel technology. Chevron, the second-largest oil company in the United States, announced at the end of 2007 that it would collaborate with the Department of Energy’s Renewable Energy Laboratory to research microalgae biodiesel technology. At the same time, to reduce the energy consumption and costs associated with microalgae production, extensive experimental research is still needed to develop low-energy, cost-effective oil extraction techniques
Current CO2 sequestration technologies are not yet mature; reliance is still mainly on emission reduction. By developing new energy sources, the CO2 released each year due to Arctic ice melting can be utilized to cover needs for a certain period of time. Hehe.
Planting trees is the best solution; by planting more trees, as long as China’s forest coverage increases, CO2 emissions should not be a problem. Currently, the world is cooling down again, and it’s not scientific to claim that CO2 is the main greenhouse gas
