How data were acquired	The blend of oil was obtained via ratio blending 10:90 (BTO10), 20:80 (BTO20), 30:70 (BTO30)….., 90:10 (BTO90), respectively. Developed catalyst was synthesized from calcined Theobroma cacao pod husk. Catalyst analysis and characterization were carried out using SEM, FTIR, XRD, and BET analysis. The design of experiment, effects of variables, determination of coefficient of determination and process variable optimization to evaluate the optimum FAEE was obtained using hybrid design. Analysis of variance (ANOVA) was used to confirmed variable significant. Quality of FAEE was determined through AOAC (1997) [1] standard methods. The efficiency of the catalyst was carried out through refining, purification and reusability test. The quality of FAEE was ascertained by comparing with biodiesel recommended standard [2], [3].
Data format	Raw, Analysed
Description of data collection	WUVO was made clean by heating and filtration. Beef tallow was made into pure beef tallow oil. Cocoa husk was calcined. Oil blend was carried the ratio in the ratio of 10:90, 20:80…..90:10 [5]. The synthesis of FAEE was via transesterification method [4]. Catalyst basic strength was tested by reusability test. The qualities of FFA meet biodiesel standard [2], [3]. All raw data are within the article.
