Expert designed, built and ran a pressure swing adsorption (PSA) unit as part of his Ph.D work. The unit separated hydrogen from synthesis gas produced from the pyrolysis of biomass at high temperatures with a goal to optimize cycle hydrogen recovery. A purity of 97% and a cycle recovery of 65% were obtained. The single adsorption bed contained molecular sieve 5A at the top and activated carbon at the bottom. Biomass pyrolysis is analogous to natural gas reforming in conventional hydrogen production systems. The expert has also designed and developed Fischer-Tropsch catalysts for the production of jet fuel using synthesis gas from the thermochemical conversion of biomass. This catalyst being heterogeneous in nature like those used in hydroprocessing reactors – hydrotreater, hydrodesulfurization and hydrocrackers means i can handle catalysts with the ability to test, regenerate and monitor their performance in a plant.

Expert has worked as a Process Design Engineer for Ventech Engineers International LLCand for Converde Energy USA (both in Texas, U.S.). This experience afforded him the opportunity to work on multiple projects involving the design of Gas Treatment and Processing Unit Operations, crude distillation and upgrade to final products such as gasoline, kerosene, jet fuels and diesel and the conversion of synthesis gas to liquid fuels using Fischer-Tropsch catalysts -- the so-called Gas to Liquids (GTL) technology.

Expert offers services in the areas of biomass conversion technologies for energy purposes and oil and gas process engineering (upstream, midstream and downstream), as well as Pressure Swing Adsorption for gas separation.
