Passport renew

I lost my chinese passport, but still have the copy of it. My passport is going to expire in July, is there anybody who can tell me how I can get it renewed?

The following are my questions:

1)Is the copy of my passport good enough to get it renewed?

2)If not, what kind of supporting documents does the Chinese Embassy still need?

3)If I go to Chinese consul in LA personally, can I get it done immediately for my case? if not, how long do i need to wait?

Many thanks in advance!!
