CONVERSION OF USED COOKING OIL TO BIOFUEL USING SOLID ACID CATALYST WITH MULTI-POROUS SYSTEM
Biofuel has recently attracted huge attention in different countries all over the world as an potentially alternative fuel sources. The term “biofuel is referred to as liquid or gaseous fuels for the transport sector that are predominantly produced from biomass. Biomass can be converted into liquid and gaseous fuels through thermo chemical and biological routes. There are different ways to biofuel production from biomass such as dilution, microemulsification, pyrolysis, catalytic cracking and transesterification. Most of the biofuel that is currently made uses vegetable oil. The high value of vegetable oil as a food product makes production of a cost-effective fuel very challenging. However there are large amounts of low-cost oils and fats such as vegetable oil sludge, restaurant waste oil and animal fats that could be converted to biofuel. This paper summarizes the main results of study on catalytic cracking process of used cooking oil to biofuel using multi-porous solid acid catalysts (H-ZSM-5 and HY). The ZSM-5 catalyst is successfully synthesized using silica from rice husk without template agents. It has got both of microstructure and mesostructure. The catalytic cracking reaction over the ZSM5 multi-porous solid acid catalyst is more preeminent than that over HY zeolite synthesized using silica from rice husk. The conversion of the catalytic cracking reaction over H-ZSM-5 (over 80％) are much higher than that over the HY zeolite (～60％). The obtained results have found a new way in the salvage of used cooking oil to produce bio-fuel by catalytic cracking process.
