The Claim
Carbon dioxide is produced as a by-product during Fischer–Tropsch synthesis when using a Raney cobalt catalyst, but only at temperatures exceeding 280°C, indicating that the water-gas shift reaction becomes significant under high-temperature conditions.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When making fuel from gas using a special cobalt catalyst, it only makes carbon dioxide as a side effect if it gets really hot—above 280°C—because at that temperature, a different chemical reaction starts kicking in.

Carbon dioxide is produced as a by-product in Fischer–Tropsch synthesis using a Raney cobalt catalyst, but only at temperatures above 280°C, suggesting the water-gas shift reaction becomes significant under high-temperature conditions.
What the research says
1 studyStudy: Fischer–Tropsch synthesis using active cobalt catalyst
Scientists tested a special cobalt catalyst to make fuel from gas, and found that it only made carbon dioxide when it got really hot—above 280°C—just like the claim said. This happens because a chemical reaction called the water-gas shift kicks in at high heat.
