Renewable base oil from biomass-derived platform chemicals
Purpose and goal
The project aims to explore a proposed new value chain of high molecular weight base oils produced from forest and agricultural residues such as hemicellulose or other polysaccharides. The objective of the project is to investigate and determine appropriate process conditions and catalysts for the proposed synthetic steps, as well as to produce a hydrocarbon mixture of sufficiently high molecular weight distribution to enable an exhaustive assessment of its suitability as renewable base oil and further applications.
Expected results and effects
The project is expected to answer if the final product can be obtained with sufficient viscosity and quality, as well as indicate the conditions required for effective hydrogenation to the final product. A possible process for producing a renewable base oil, technically equivalent or better than its fossil equivalent, is a major step forward for oil refineries to evaluate opportunities and constraints to become more aligned with a bio-based economy
Planned approach and implementation
The project will be jointly run by RISE and Nynas. RISE will perform the practical synthetic work and Nynas conducts the performance evaluation of products. Initially, high molecular weight derivatives will be synthesized from platform chemicals of hemicellulose. Prior the hydrogenation step, careful formulation strategies of the high molecular weight feed are expected. The formulated material will be hydrogenated in batch reactor. The collected data will be used to adapt the process to equipment that mimics continuous refinery infrastructure.
