Detailed Research Accomplishments:
Current Research Activities – Transformation of lignocellulosic biomass to chemicals and fuels: 1. Sugar Isomerisation and its direct conversion to biofuels: Objectives: The goal of this project is to develop a non-enzymatic approach for the interconversion of glucose to fructose - as it has potential application in making High Fructose Corn Syrup (HFCS)- and to produce biofuel such as ethyl levulinate and 5-ethoxmethylfurfural (EMF). Major Achievements: • Developed a new reaction protocol where fructose can be produced from glucose in high yield (>50 %) in one-pot two-step using zeolite as catalysts. • Developed a reaction protocol to make ethyl levulinate (50%) directly from glucose and other carbohydrates using zeolites-containing Brønsted and Lewis acid sites. • Developed a method to produce 50% and 70% EMF, biofuel, from glucose and fructose, respectively, employing nonporous zeolites as catalysts. •Outcome results published in high impact journals such as JACS, Green Chemistry, ChemSusChem and 2 patents. 2. Hydrogenolysis of alpha-hydroxyester: Objectives: The ambition of this project is to investigate mixed oxide catalysts for the selective hydrogenolysis of alpha-hydroxyesters to propionates. Major Achievements: • Developed nano-sized mixed metal oxide catalysts that can selectively convert lactates to propionates above 70%. • This invention has been filed for a patent. 3. Sugars to lactic acid (Milk acid): Objectives: The ambition of this project is to study and develop an alternative heterogeneous process to the biochemical process- fermentation of glucose to lactic acid- as lactic acid is one of the bio-platform chemicals and potential precursor for making bio-degradable plastics. Major Achievements: • Invented a process to make methyl lactate, precursor for bioplastics, from sugars in high yields ( 70%) using solid Lewis acid-containing zeolites. • The accomplished results published in a reputed journal Science. • This achievement has been highlighted in the following research newspapers: Chemical and Engineering News, Chemistry World, Videnskab.dk, and Ingenioren. • Technology Transferred to Danish company Haldor Topsøe in 2008/2009. 4. Carbon Capture using ionic liquids: Objectives: The aim of this project is to find out suitable functionalised ionic liquids as reversible absorbents with enhanced CO2 absorption capacity, as current flue gas cleaning technology suffers a lot with traditional aqueous solution of monoethanolamine (MEA). Major Achievements: • Achieved to synthesise amino acid functionalised ionic liquids which can uptake higher than two moles of CO2 per mole of ionic liquids. This is the highest CO2 absorption capacity that has been disclosed in the literature at that point. • This invention led to two patents and the results published in a high impact journal ChemSusChem. 5. Microwave-assisted synthesis and catalytic application of micro- and mesoporous materials: Objectives: :The major purpose of this project is to find out the influence of microwave compared to conventional method for the synthesis of microporous and mesoporous materials. Major Achievements: • Morphology of the functionalised SBA-15 materials can be controlled by microwave treatment. • Narrow mesopore size distribution of H-ZSM-5 was achieved using microwave over conventional heating treatment.
Research Challenges and Future Direction:
• Lignin valorisation: Aim: To develop facile and efficient methods for the isolation of lignin from woody biomass and to improve the yield of similar aromatic compounds from the isolated lignin, as the lignin is the one of major sources for aromatic compounds that can substitute fossil-based aromatic compounds • Direct conversion of cellulose/hemicellulose to chemicals and fuels One of the major challenges in woody biomass conversion is to directly transform cellulose to the targeted chemicals, for example, lactic acid, as cellulose has very limited solubility in aqueous and most organic solvents that hampers the upgrading of cellulose conversion. Aim: To develop a chemo and integrated chemo-enzymatic process where cellulose can be hydrolysed to monomeric form of glucose at low temperature without significant amount of degradation, followed by chemo-catalytic, for example, nanoporous zeolites, conversion to the targeted products.
