| Abstract | Although the independent effects of the predictors of the yield in transesterification are well documented, there are still gaps in our current understanding of how specific process variables cumulatively influence the yield of biodiesel. In this study, a two-level Plackett–Burman experimental design was used to assess the set of active process variables that most decisively influence the yield of biodiesel in transesterification. The results of the model in which the parameters were entered at once show in decreasing order, the magnitude of the effect of the process variables on the yield was as follows: amount of FFA > weight of catatlyst > rate of stirring > duration of reaction > temperature > methanol for the ranges of values that were studied. In the sequential/nested ordinary least squares regression model, the order of importance of the predictors was almost maintained however the coefficients varied somewhat. This indicates that the level and the order of entry of variables within each level makes a fundamental difference to the results. The methanol-oil ratio had no influence on biofuel yield within the range of values studied. Overall, the adjusted model in which most of the variables had been taken into consideration explained approximately 94 % of the total variance in the data. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
