You have to be sure to have a fuel source in your inventory somewhere - redstone, coal, glowstone dust, gunpowder, or a charged klein star.

You don't need a gem of eternal density for the destruction catalyst to work, but it does go very well with the destruction catalyst as the gem of eternal density will "eat" almost everything the destruction catalyst collects and convert it into more valuable items.
