Production of renewable fuels in existing refinery assets: A cost-effective coprocessing strategy
Vegetable oils are a renewable biomass resource used in the production of biofuels. Biodiesel production from transesterification of vegetable oils (fatty acid methyl ester, or FAME) is the primary route for producing biofuels from vegetable oils.
Use a mixed-solvent process to boost lube base oil yields and profitability
Through research and development (R&D), the commercial application of a mixed-solvent (MS) approach using a mixture of different co-solvents resulted in higher lube raffinate yields without affecting the lube oil quality.
