The present disclosure relates to a process for the hydrodeoxygenation of vegetable oils or animal fats to produce green diesel, which comprises contacting the vegetable oil or animal fat with a Nickel-Molybdenum or Cobalt-Molybdenum catalyst supported on alumina-titania or titania, respectively; in a fixed bed reactor in the presence of hydrogen. The process involves hydrocracking, hydrogenation, decarboxylation, decarbonylation, carried out in a fixed bed reactor at temperature of about 270 C. to about 360 C., pressure of about 40 kg.sub.f/cm.sup.2 to about 60 kg.sub.f/cm.sup.2, liquid hourly space velocity (LHSV) between about 0.8 h.sup.1 to about 3.0 h.sup.1, and H.sub.2/oil ratio of about 2,700 ft.sup.3/bbl to about 7,000 ft.sup.3/bbl, that allows to obtain a conversion up to 99% and up to 92.7% yield on green diesel.

The present invention discloses a method for preparing biodiesel (Methyl Ester) from any kind of oil, vegetable or non-vegetable oil or used cooking oil. Further, it relates to a method for preparing biodiesel (Methyl Ester) with 100% purity which can be directly used as a fuel in cars, trucks, buses industrial and domestic purpose without any need to blend with any petroleum diesel. The present invention also discloses the biodiesel having improved cold flow properties, flash point and 57 cetane number with reduced exhaust emission where CO.sub.2 emits approx. 2.96% v/v and CO emits approx. 0.2 ppm % v/v.
