IMPROVEMENTS TO SEPARATION OF PRODUCT STREAMS

摘要

A method of purifying a vapour product stream obtained from cracking of biomass catalysed by a fluidised solid catalyst is provided. The catalyst is separated from the vapour product stream to provide a de-catalysed vapour product stream. Solid biomass residue is cyclonically separated from the de-catalysed vapour product stream to provide a purified vapour product stream.
