Perhaps try some high speed vibration the get it moving. Use a bolt or the back end of a drill bit in a common hammer drill. Or an air chisel if you have one.
How do I pull this pulley wheel off ?

kroil and acetelyene torch to the hub. Even Mapp gas torch would help.

Find out where the set screw is and remove it, support the back of the hub and get it red hot really fast,(oxyg/acct)let it cool just a bit and drive the shaft out. I've done thousands this way.

I've done this before with some added heat with good results on snowblower drive pulleys. Rob's idea about welding the nut to the hub is a good one too, you may need a piece of pipe in there for a spacer though.
In general, heat is your friend, once the hub expands even a little it should be free enough to come loose with reasonable force.
After saying that, I used a hydraulic press to remove a snowblower wheel from the axle years ago. It was red-hot at the time, and still needed almost 12 tons to break it loose. Not good.

You could also use one of these. Drill two holes through the pulley the appropriate distance apart for the puller rods, install the bearing separator plate, get it all ready to go, apply tension on it and then heat the hub and then when it's hot, give the end of the threaded puller shaft a good whack with a hammer and see if that breaks it loose. If it doesn't, apply more heat, and repeat.

From the looks of that, I think you're wasting your time with anything but the blue wrench...

Not all Keyways have set screws. Some are just press fit. The half moon one especially.

If it has a set screw take it all the way out and check and see if there is a second set screw under the first one.

Heat up the hub and melt some wax into it instead of penetrating oil. I saw this trick in here somewhere and some said it worked like a charm. I haven't had a chance to try it yet.
