Huang, head of Hong Kong-based investment company QSL Sports Ltd, wants to take full control of the Reds, who have been up for sale since April.
"A deal has to be done before the transfer window closes [on 31 August]," a source close to Huang told BBC Sport.
"Huang has made a firm proposal. The club's board has to sanction the sale and it could be sewn up in days."
Huang has been talking for several weeks to representatives of the Royal Bank of Scotland, with the aim of taking full control of the Premier League club.
RBS are Liverpool's main creditors, owed about £237m by American co-owners Tom Hicks and George Gillett.
"Kenny is the only serious bidder interested in the club and he's optimistic," added the source.
