What is the difference between a business account and a personal account?

Business accounts are designed for people who only want to use Facebook to administer Pages and their ad campaigns. You can use a business account to view all the Pages and Social Ads you’ve created. You can also see public info about other people on Facebook from a business account, but you can’t interact with those people outside the context of your Page. And, unlike personal accounts, business accounts can’t be found in search, send or receive friend requests or create/develop apps.
