A process is described for producing a hydrocarbon product. In examples, the process comprising contacting a feedstock with a catalyst composition in the presence of hydrogen, the feedstock including a lipid, and the catalyst composition being active for conversion of the lipid to the hydrocarbon product in a single step. The catalyst composition comprises an M1-8 Sup] catalyst, where M1 is an active metal and [Sup] comprises an acidic support. In examples described, the process is used in the production of diesel-range fuel and/or jet fuel from lipid having a high yield of C11-C24 branched alkanes with high cetane value and low freeing point. In examples, the hydrocarbon product includes greater than 70% measured by weight of C11-C24 alkanes based on the weight of the lipid, and the content of branched alkanes of the C11-C24 alkanes is greater than 60% measured by weight of branched C11-C24 alkanes based on the weight of the C11-C24 alkanes.
