Provided is a conversion process for an organic oil, relating to the field of biomass utilization, energy and chemical industry. The conversion process is carried out in presence of an aqueous slurry and a catalyst selected from the group consisting of an iron oxide compound, a waste agent resulting from use of an iron oxide compound as desulfurizer, and a regeneration product of the waste agent, under a controlled molar ratio of iron element to sulfur element. It is found that free radical condensation polymerization of organic oil during cracking process can be blocked effectively by using carbonylation, and hydrogenation is achieved with active hydrogen produced from the conversion of CO and water. In the conversion process, organic material, especially biomass solid, can be directly converted without dehydration, and water can be additionally added to the biomass liquid or the mineral oil.
