NASA is looking for a process to use CO2 as a Carbon source on Mars; ultimate goal is to use the Carbon in the synthesis of other products.

$50,000 prize.

Open to U.S. citizens, permanent residents, and U.S. business entities, work must be done in the U.S.,

Looks like Navy might have a head start. They can make jet fuel out of the CO2in seawater.

I'm not enough of a chemist to assess difference between hydrocarbons and carbohydrates though.

Seems right out of Science Fiction's Golden Age, doesn't it ?

Look into Fischer-Tropsch synthesis.

"Liquid transportation hydrocarbon fuels and various other chemical products can be produced from syngas via the well-known and established catalytic chemical process called Fischer-Tropsch (FT) synthesis, named after the original German inventors, Franz Fischer and Hans Tropsch in the 1920s," and it was industrialized in the 1930s.

CO2 can be decomposed in a hydrogen environment with electrolysis, or electrical discharge, or radiolysis. One can produce methylene, and even carbon black. That's been known for decades.

So the Sabatier process, researched for Mars Direct project, is no longer a valid option?

Apparently, they like sugars as outcome.

I would expect that the synthesis steps (=this challenge*) are the easier parts - you can use well-established processes from Earth. Cleaning the CO2 from dust and the other gases is a challenge unique to Mars.

* according to the rules you can use a source of pure CO2.
Other consumable reagents/catalysts are of course allowed as part of the conversion process (e.g., acids/bases/metals).
That is interesting (highlight from me).
