TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The catalyst is a zeolitic catalyst that is gallium-modified to comprise gallium cations in a ratio of 1/1 gallium/framework-aluminum. The catalyst is a gallium-doped form of at least one zeolite-alumina matrix catalyst with pore sizes of 10 oxygen atoms in the pore mouth. The catalyst is a gallium-doped form of a zeolitic catalyst including ZSM-5, ZSM-11, ZSM-23, MCM-70, SSZ-44, SSZ-58, SSZ-35 or ZSM-22. The gallium-cation catalyst is present at 1-100 (preferably 90-100) wt.% in the reactor vessel or riser. The weight percentage of gallium-cation catalyst in the reactor vessel or riser is equal to the weight percentage of renewable oil in the feedstock. The catalyst further comprises a Y-zeolite FCC catalyst in the riser. The catalyst comprises gallium cations.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The riser is a fluidized catalytic cracking unit (FCC) riser. The reactor vessel is a moving-bed vessel adapted so that the catalyst moves through the reactor vessel by gravity. The reactor vessel is a fixed-bed reactor.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The contacting is done in a single reactor. The contacting is done in a series of at least a first reactor and a second reactor, where liquid is removed from the intermediate product stream between the first and second reactors, and vapor from the first reactor is fed to the second reactor. The contacting is done in in a fixed-bed reactor, in a moving catalyst bed or a riser of a fluidized cracking unit. The contacting is done at 510-555 degrees C or 400-555 degrees C for 2-4 seconds. The renewable oil is algae oil that has not been processed between being extracted from algae and the contacting. The algae oil is processed or not processed in a refining, bleaching, and deodorizing (RBD) process and/or a degumming process, where the algae oil is hydro treated before contacting. Preferred Components: The renewable oil is canola oil, preferably crude algae oil extracted from a green alga or a blue-green alga. The product stream comprises benzene (greater than 15 wt.%). The feedstock comprises the renewable oil (1-100 wt.%, preferably 90-100 wt.%). The elevated temperature is 375-425 degrees C or 350-555 degrees C. The renewable oil is obtained from a non-vascular photosynthetic organism. The feedstock is oil (100 wt.% or 1-20 wt.%) obtained from a nonvascular photosynthetic organism. The oil obtained from a nonvascular photosynthetic organism is extracted from naturally-occurring algae or cyanobacteria, preferably genetically-modified algae or cyanobacteria. The remainder of the feedstock that is not oil obtained from a non-vascular photosynthetic organism comprising at least one fossil oil fractions, at least refined fossil oil products or fractions, naphtha, gasoline, jet fuel and/or diesel. EXAMPLE - Zeolite catalyst (10 g) was loaded into the reactor. Borosilicate glass beads (10 g) were poured on top of the zeolite. Reactor was loaded into the furnace. Nitrogen flow was established. For the gallium-containing materials, the reactor was brought to temperature for activation and the catalyst was activated. Reactor was brought to the cracking temperature (350 degrees C). Nitrogen co-feed was used during cracking. Canola oil feed was started, 0.182 ml/minute and total amount of reactant fed was 10 g.
