The reactions of a strain of marine alga Chlorococcum sp. and of a polystrain containing a mixture of marine algae with CO/H₂O have been studied. The yields and chemical composition of the products obtained from the reactions with CO/H₂O were compared with those using N₂ and H₂. The effects of selected potential catalysts (Na₂CO₃, NaAlO₂, and Fe) and the water-to-algae ratio on the product yields and composition when the reactions were carried out under CO/H₂O are also described. Both algae gave high product yields at 285 掳C, but the quality of the product as a liquid fuel increased at higher temperature. The reactions with CO/H₂O tended to give higher oil yields and higher-quality products (lower nitrogen, higher atomic H/C ratio) than those using H₂ or N₂ and, in addition, reduced the amount of dewatering of the algae that is required.
