A process is disclosed for producing renewable products, such as a renewable base oil, from a feedstock of biological origin. The process includes subjecting a feedstock containing free fatty acids and fatty acid glycerides, wherein at least one hydrocarbon chain is unsaturated, to esterification reaction in the presence of an alcohol. An ester stream thereby obtained is then subjected to metathesis conditions in the presence of a renewable alkene to obtain a metathesis product. Separation of the metathesis product includes recovery of a fraction containing or consisting essentially of C16 fatty acid esters, which is subjected to ketonisation reaction conditions to produce long chain ketones, which after hydrotreatment meet requirements for a renewable base oil. Ketonisation reaction produces renewable alkene usable in metathesis reaction.
