I want to run a 1.5" drain pipe along the wall about 2 feet from the floor to a microbrewery setup in the corner of my basement. I have sheets of fiberglass insulation against the walls though, and I don't want to remove them. What kind of hanger/ mount can I use to run it along the wall, but about 4-6 inches off the wall?

I would recommend not doing what you suggest, here's why:
A typical rough-in for a clothes washing machine is as show in the picture below and consists of the following:
- vent
- 2" p-trap
- vertical section of 2" pipe above the p-trap
- (an actual outlet box as shown is not required, you can just use the plan end of the pipe)
Your discharge hose will fit inside the 2" pipe opening and will usually enter the pipe about 6" to 8". This connection is not water/air tight.
The size of the p-trap and the vertical section of pipe are to accommodate for the flow rate of the washing machine's discharge. The p-trap will create a restriction to the flow and the vertical pipe allows for some head water to buildup without putting any back pressure on the washing machine's internal pump.
A p-trap is a must as it will prevent sewer gas from entering your house. The vent is required to protect the water seal of the p-trap but can be replaced with an air admittance valve depending on local codes.
I would imagine that if your machine can pump that high it will be near its limit and without any room for a vertical section of pipe to discharge into you will have to make the connection sold which will put additional back pressure on to the machine's pump (even more due to the pipe size only being 1.5") which will shorten the life span of the pump.
From the 2012 International Plumbing Code Section 1106, I get a pipe diameter of 3" based on table 1106.3 and this map:

They make shelf brackets that have a U shaped hook on the end away from the wall. I've seen them in a variety of sizes, down to about 6" (don't know about 4"). That would be pretty easy, just space some of those out at the height you want, then lay the pipe in the "trough" created by the hooks.
I guess they're called shelf and rod brackets. Here's a link, though it's probably too big for what you want.
This one looks perfect for what you want, but I don't see how to buy it..
Do a google search and a google image search for "rod bracket" "shelf and rod bracket" you'll see ones made for closets, but also others for curtain rods, which tend to project less from the wall. I did a search for '6" rod bracket' and saw many potentials, at a range of price points.
