Foreign currency exchange at Capital Airport?

Yes! You can convert Egyptian pounds to CNY or USD at PEK. There are many spots at PEK, including Travelex in Domestic Arrival Hall, F1, T1; Hang Seng Bank in International Arrival Luggage Hall, F1, T2; Travelex in International Arrival Luggage Hall, F2, T3-C. You can consult the staff at the Exchange Point about the exchange price and limit. Good luck! :)
