Abstract: The present invention relates to a method for preparing conjugated linoleic acid methyl ester from linoleic acid methyl ester contained in bio diesel produced from animal/vegetable oil waste resources by using nickel-supported zeolite heterogeneous catalysts. In the present invention, if using the nickel-supported zeolite heterogeneous catalysts for preparing the conjugated linoleic acid methyl ester, environmental loads can be reduced compared to conventional homogeneous catalysts and precious metals heterogeneous catalysts by reducing energy costs, the wastewater generation amount, etc. and selectivity of separation can be significantly increased thereby separating the conjugated linoleic acid methyl ester in high yield so as to provide the same as a raw material required for manufacturing cyclic dimer acid.
