2 O have been investigated as catalysts for the transesterification, esterification and pyrolysis of vegetable oils. The compounds were characterized by thermal analysis (DTA-TGA), spectroscopy (DRX, FT-IR and FT-Raman), surface area (BET) and the acidity (Ho) determined by n-butylamine titration using the Hammet´s indicator method. It was observed that after the acid treatment both the surface area and the acidity decreased as compared to the starting Nb 2 O 5 •xH 2 O. The only exception was a higher acidity verified when nitric acid was used. Among the catalyst investigated, the Nb 2 O 5 /H 3 PO 4 presented the highest activity in the alcoholysis of soybean oil with different mono-alcohols (methanol, ethanol, 2-propanol, n-butanol

“…%, respectively. This corresponds to increases by factors of approximately 1.27 and 2.48 and can be explained by secondary cracking reactions of intermediate fatty acids being mainly activated by the catalysts' acid sites [8,10,16] and leading to the production of desirable hydrocarbons. Hence, increasing the CTO ratio provided more active acid sites in the reaction system; therefore, more gasoline and lower olefins were produced.…”

“…To avoid such a phenomenon, medium pore size offering zeolite ZSM-5 has been investigated in the cracking of triglycerides [8][9][10]. With the pore opening size of 0.52-0.56 nm and pore intersection size of 0.8 nm, ZSM-5 selectively directs the cracking process toward the formation of C5-C10 hydrocarbons corresponding to the gasoline-boiling range while avoiding the formation of poly-aromatic species.…”

“…With the pore opening size of 0.52-0.56 nm and pore intersection size of 0.8 nm, ZSM-5 selectively directs the cracking process toward the formation of C5-C10 hydrocarbons corresponding to the gasoline-boiling range while avoiding the formation of poly-aromatic species. Unfortunately, a high gas yield with low concentrations of light olefins is generally observed [9,10], implying the occurrence of undesired secondary reactions because of the diffusion limitations caused by the relatively small pore size of ZSM-5. Accordingly, the modification of ZSM-5 zeolites to enhance the selectivity to C2-C4 olefins has been extensively studied in recent years.…”

Abstract:The catalytic cracking of triglyceride-rich biomass toward C2-C4 olefins was evaluated over a hierarchically textured nano-ZSM-5/SBA-15 analog composite (ZSC-24) under fluid catalytic cracking (FCC) conditions. The experiments were performed on a fully automated Single-Receiver Short-Contact-Time Microactivity Test unit (SR-SCT-MAT, Grace Davison) at 550 °C and different catalyst-to-oil mass ratios (0-1.2 g•g −1 ). The ZSC-24 catalyst is very effective for transformation of triglycerides to valuable hydrocarbons, particularly lower olefins. The selectivity to C2-C4 olefins is remarkably high (>90%) throughout the investigated catalyst-to-oil ratio range. The superior catalytic performance of the ZSC-24 catalyst can be attributed to the combination of its medium acid site amount and improved molecular transport provided by the bimodal pore system, which effectively suppresses the secondary reactions of primarily formed lower olefins.

Summary:This review paper examines the use of steam reforming to convert bio-liquids like ethanol, glycerol, butanol, vegetable oil, bio-oils and biodiesel into hydrogen gas. The focus of the research was to investigate the research being undertaken in terms of catalyst developments for the steam reforming of the above mentioned feedstock, and to determine the perspective opportunities in this area. Hydrogen production by steam reforming of biooil, ethanol, and pure glycerol has been widely investigated; several thermodynamic and catalytic investigations are available restricting new investigations. In contrast, hydrogen production from waste streams, vegetable oil, biodiesel and butanol is very recent and has room for further developments.
