Conversion efficiency of soybean oils to biodiesel using LiAlO2 can reach 97.45%. The catalytic results revealed that LiAlO2 maintained its activity after six catalytic runs. a r t i c l e i n f o a b s t r a c t Article history: The LiAlO2 catalyst was prepared by solid-state reaction and then applied to the biodiesel production by Received 17 March 2015 transesterification reaction between methanol and soybean oil. This was the first attempt to use LiAlO2 as Received in revised form 5 June 2015 a catalyst for biodiesel production. It was found that the catalyst of 4 (mol(Li CO )/mol(Al O )) being cal- 2 3 2 3 Accepted 9 June 2015 cined at 900 C showed the optimum activity. XRD, BET and
