Summary Magnesium‐alumina (Mg‐Al 2 O 3 ) composite was synthesized by sol‐gel method. The SO 4 2− catalyst supported Mg‐Al 2 O 3 was prepared by three different methods such as solution, hydrothermal, and vapor phase. The as‐synthesized materials were characterized by different physicochemical techniques. The acid sites of Mg‐Al 2 O 3 (10) composite were enhanced by depolymerization of triglyceride (jojoba oil) to produce free FFA. Catalyst prepared by hydrothermal methods exhibits high acid sites of 3.44 mmol g −1 of NH 3 . Sulfidation of catalysts play a vital role in the catalytic conversion of jojoba oil by methanol activation. SO 4 2− /Mg‐Al 2 O 3 (10) catalyst reveals 99% conversion efficiency tested under optimized conditions of jojoba oil to methyl ester (biodiesel). TGA result confirmed the S2/Mg‐Al 2 O 3 (10) catalyst is stable upto 800°C and weight loss of 19.2%. The recyclability of the S 2 /Mg‐Al 2 O 3 (10) catalyst reveals reasonably acceptable conversion efficiency after sixth cycle and this catalyst is found to be suitable for the industrial biodiesel production.
