Here's my reaction, what's my catalyst?

Question

Alan Turing (the very same!) gave me some very useful advice on converting hydrogen into methane using CO2. The reaction is

CO2 + 4H2 --> CH4 + 2H2O

What I'd like to know next is: what catalyst, what temperature and what pressure do you think I would need to achieve this reaction? And any other activities you think might help?

Also, what would the energy balance be? We're reducing the CO2, so we need some energy in, but some of our hydrogen is turning into water, so we get some energy out. What's the net sum?

Hey! stop giving each other bad marks! and yes the reaction is a bit upside down - that's why I want to do it. It's all for benign purposes, I promise!

Answer 1

There are two posibilities:

1) biological. Use the methanococus jannaschi bug.
2) chemical. Use an iron-ruthenium or iron-nickel based catalyst

Answer 2

HI,

Not sure, but it looks the kind of reaction that might be better done with an enzyme.
If I remember rightly, an enzyme called Catalase splits up H2O2 ( Hydrogen peroxide). Perhaps you could try to grow cultures of bacteria in an environment containing both CO2 and H2. Although 99.9% might die off, through numerous mutations that always occur in bacteria, the few that survived could carry out the required reaction.

Answer 3

Catalysts %. up chemical reactions. least perplexing very minute parts of the catalyst are required to furnish a dramatic substitute interior the rate of the reaction. it quite is quite thinking the reaction proceeds through another pathway whilst the catalyst is present. including added catalyst will make needless to say no substitute. the only diverse important ingredient you need to bear in mind approximately catalysts is they are no longer ate up interior the direction of the reaction.

Answer 4

Heat and pressure are interchangable. PV=nRT
The more pressure you have, the less heat you'll need; the more heat you have the less pressure you'll need.

There are some bacteria that carry out this reaction in a process called methanogenesis.

Answer 5

Certain bacteria do manage this reaction, but I don't believe you will find a feasible way to perform this reaction chemically.
