For DefaultButton of Panel to work you have to have the Panel in focus... In your code the Panel in focus is the first (as it comes first...) and it has no DefaultButton whatsoever...
If you want the button be a global default, use DefaultButton property of the form...

m not getting so can u please explain more

You have two panels - one with default button attached and one without...
As long as the panel with the default button attached NOT in focus the DefaultButton property is meaningless. The reason is that it is a private definition to that specific panel, but key events are bubbling from the focused element up to the form level...
In your code the panel in focus is the first one so any key event hits it first, than goes up to the form and never hits the second panel...

Solution 2

Add a default button to the parent panel.

ASP.NET

<asp:Panel ID="someOuterPanel" runat="server" DefaultButton="btn_Process">
   <asp:TextBox id="someTextBoxOutsideInnerButtonPanel" runat="server" />
      ... other buttons and stuff...
   <asp:Panel ID="pnl_BeneficaryDetails" runat="server" DefaultButton="btn_Process" > 
         <asp:ImageButton runat="server" ID="btn_Process" OnClick="btn_Process_Click" Visible="false" ImageUrl="~/image/process.png" ToolTip="Process Payment" />

DefaultButton="btn_Process" , this code is not working here , I have already use this soution on other page which working fine , but not working in this code because nested panel is used here ..

You probably do not need the DefaultButton on the pnl_BeneficaryDetails since it's on the outer panel (someOuterPanel)
