The present invention relates to a process for the purification of biological feed material and to a process for catalytically converting the purified biological feed material into hydrocarbons suitable as biofuel components. The purified feed material is treated in a reactor system including a catalytically active guard bed phase and a catalytically active main reaction phase. At least one of the phases includes a catalyst bed with a combination of hydrodeoxygenating (HDO) and hydrodewaxing (HDW) catalysts. The process provides biofuel with acceptable ignition and cold flow properties.
