What are the by products?

If you mean waste, non.
By Products are not really such either. They are simply fractionating Hydrocarbon chains to whatever lengths (products) they want.

A hydrocarbon consists of hydrogen and carbon. Isolating hydrogen will leave carbon, if the splitting of the hydrocarbon involves a catalyst it will be carbon and something else.

Hydrogen + Oxygen = Water.  That is the result of hydrogen "combustion".  It isn't a Hydrocarbon.

BP, there is no catalyst. It's simply a fractionating tower at a refinery. They make what they want depending on how they control the process. The differing products come off at different levels. Gasses are at the very top of the Tower. They are working with simple Hydrocarbon chains at the very top. Hydrogen and Carbon. The combinations of such make what they are after. All kinds of products are made at refineries. Not just oil, petrol and gas. Left overs of one molecule are added to another to make something different.

Lets just say though, that there was an excess of pure carbon left over. There is a huge market for pure Carbon. So everything can be used. There is no stream of black waste being trucked to the local landfill or dumped somewhere if that is what you think.

Thats what I'm after, what happens to the carbon? I doubt it comes out pure, but where does it go?

Is this what you mean?

methane reforming reaction
CH4 + H2O (+ heat) → CO + 3H2

Water-gas shift reaction
CO + H2O → CO2 + H2 (+ small amount of heat)

Last Sunday was privileged to go for a test drive in a Tesla model 3,0 to 100 in 3 seconds,full charge 650km apparently and if charged at home $2. $90k though. battery they say will last at least 300thousand kms before replacement.

Hmm,Tesla specs dont agree with that. Longest range model is the 2wd long range, (just discontinued) claimed 512km on a 75kwh battery. At nz average power costs of round 20c per kwh, that's about 15 odd dollars...
Still a cool car though, I'd have one .

There is nothing, absolutely nothing, half so much worth doing, as simply messing about in boats

There's ample thrust from the 258-horsepower electric motor, and it moves out in a smooth, seamless way with no shifting interruptions. The rear-wheel-drive layout adds poise and confidence when you lay into it. Ours reached 60 mph in 5.3 seconds at our test track, which is properly quick. Dual-motor Model 3s are even quicker.

Our panic stop from 60 mph took 123 feet, 

 but this one has a range over 300miles (480 ish)

One of the Model 3's big selling points is its range, and we think most buyers should strongly consider the Long Range Battery version.

 

 

It,you know what salesman are like :razz:
