Abstract

The prospect of producing bioethanol from biomass available locally is in the interest of widespread sustainable growth and development.   The novelty of our study focused on maximising the recovery and purity of bioethanol from dates by subjecting the process to specialised treatment for removal of water and toxic species. Bioethanol production from dates of the Fard and Khalas cultivars is relatively unexplored, and was achieved by adopting standard protocol of thermal sugar extraction followed by fermentation and distillation. Water de-contamination of the product utilising molecular sieve treatment led to enhanced purity of bioethanol (98%). Co-treatment with sodium borohydride resulted in reduced levels of toxic species Cr3+, Cr6+ and As3+ by about 20%. The speciation study was conducted using hybrid liquid chromatography/mass spectrometry (HPLC-ICP-MS). A built-in dynamic reaction cell facilitated detection of the species of interest. Elemental profiling of bioethanol samples employing standard ICP-MS demonstrated that the levels of trace elements were higher in general for the Fard dates. Our research is significant from the perspective of deploying surplus dates for biofuel production to obviate competition for arable land.  The study could make a useful contribution to ongoing research associated with climate change.
