A process for pretreating biological feedstocks for hydroconversion in a fixed-bed reactor. A feed stream having free fatty acids, fatty acid esters, or combinations thereof is contacted with a citric acid solution. The biological feedstock is separated from the aqueous solution to efficiently produce a pretreated biological feedstock substantially absent of metals and phosphorus.
