Objective

My job objectives include the scale up of Biorefinery technology. Biorefinery composed of the biomass conversion into valuable chemicals as well as bio energy. Main goals of my study is biomass conversion from biochemical routes and make this process to be well executive from lab to pilot scale. Pretreatment of biomass with steam explosion and further hydrolysis and fermentation are different steps during these studies. Optimization of conditions in lab scale experiments and further the optimized condition to be scale up in pilot scale in an economical way to make the overall process feasible for production of Bio-based chemicals. 

Current Status

Currently involved in selection of variety of biomass available for pretreatment on the basis of cellulose, hemicellulosic and lignin contents. Also, performing a literature study on various biomass pretreatments and hydrolysis and on that basis a review article is being in process of writing. Design of different processes (specially pretreatment) experiments are being in process to perform in lab scale.

Future 6-months Plan

A number of pretreatment experiments would be done on lab scale according to experiment design. Different analysis including sugars, byproduct as well as structural changes would be done in BPF as well as in TU Delft. The efficiency of successful pretreatment would be determined on the basis of hydrolysis performance. The experiments would be perform for pretreatment as well as hydrolysis and resulted products to be analyzed to make optimization for scaling up the process to pilot scale.

Secondments

Currently I am working in TU Delft as secondment for my lab experiments planning and analysis. Other secondments would be in Arkema and DTU.
