The UK Government is set to announce additional funding for Grangemouth.
Chancellor Rachel Reeves is expected to include an extra £14.5 million of investment in Wednesday's Budget.
400 workers have been made redundant, after the refinery ceased production in April.
The money will go towards the refinery's transition into a clean energy hub.
A Treasury source said: "We said we would stand squarely behind communities like Grangemouth, and we meant it.
"And we're building on what we have done already by putting millions in as a starter to help put the community on a firm footing and strengthening its places as part of the clean energy revolution.
"These investments will help deliver a fair transition for Grangemouth, securing jobs for local people way into the future."
