The photothermocatalytic process for the synthesis of hydrocarbons — including liquid alkanes, aromatics, and oxygenates, with carbon numbers (Cn) up to C13 — ran in a flow photoreactor
operating at elevated temperatures (180 — 200 °C) and pressures (1 — 6 bar) using a 5 % cobalt on TiO2 catalyst and under UV irradiation.
