A system and method for renewable diesel synthesis utilizes a triglyceride feedstock derived from biological sources. The first step involves hydrolysis of the triglycerides into an intermediate feedstock comprising a mixture of free fatty acids and glycerol (separated from the FFA by decantation and then distilled). The FFA is then further processed in a distillation step to produce a stream free of catalyst poisons and utilized as feedstock for hydrotreatment in a renewable diesel production process. By converting the initial triglyceride feedstock to an FFA feedstock, the need to hydrotreat at typical high temperature that promote the decarboxylation reaction is obviated, thereby reducing the production of CO2, generating a significantly higher proportion of saturated, long chain C14, C16 or C18 hydrocarbons (as opposed to short-chain carbons such as propane), and the more valuable glycerol product is secured.
