You can't. The name in Eco is the steam name with which you joined the server. If you change your steam name and then freshly join a server you will have a different name.

As I said above, the name cannot be changed once you already joined a server, it must be a new one or the same after they have reset their map. The name you join a server with stays until the server is reset.
