ADI conducted a technical scan of non-hydroprocessing routes for upgrading biomass-derived pyrolysis oil, focusing on solvent extraction and membrane-based fractionation. The assessment identified high-value chemical pathways for light olefin streams, benchmarking potential products like acrylic acid and lube additives against minimum economic scale (MES) requirements.
The client
Biomass conversion technology developer
The situation
Uncertainty regarding the feasibility of using novel separation and chemical conversion routes to upgrade unstable bio-oil into fuel-range fractions.
ADI’s contributions
Separation technology scan
ADI evaluated extractive distillation and liquid-liquid extraction methods, identifying water washing as a cost-effective initial step for phase separation.
Membrane feasibility study
Analysis of ceramic and polyimide systems, including Max-Dewax benchmarks, demonstrated the potential for size-based isolation of heavy fractions.
Olefin monetization filtering
Using chemistry and scale as primary filters, ADI isolated four chemical applications and two fuel products viable for low-volume streams.
Primary research insights
Interviews with experts from firms including PNNL, GTI, and ExxonMobil provided validation for stabilization pathways and “green” chemical precursor potential.
Key outcomes
- Prioritized size-based membrane filtration and specialized chemical applications to maximize the value of bio-oil light ends.

CBAM puts a new price tag on emissions
On April 7, 2026, the European Commission announced the first official Carbon Border Adjustment Mechanism (CBAM) certificate price for Q1 2026 at €75.36 per tonne of CO2 equivalent (~$88/t CO2e), marking the EU’s first explicit carbon price applied to imported goods. This rate will be applied to the embedded emissions in CBAM-covered imports and is […]

Cooling fluids are becoming a constraint in AI data centers
Immersion cooling fluids are taking on more importance as data‑center operators deploy higher‑power artificial intelligence (AI) and high-performance computing (HPC) systems. Rack densities are increasing faster than traditional air systems can accommodate, and liquid cooling is now part of the design discussion for many new builds and retrofits. In that context, fluid properties affect reliability, […]

Implications of UAE’s exit from OPEC
Part of ADI Analytics’ ongoing coverage of the implications of the Iran conflict across oil & gas, LNG, refined products, and chemicals. The UAE’s exit from OPEC (see our prior blog) in late April 2026 reflects a decisive shift toward a volume‑driven strategy focused on monetizing its hydrocarbon resource base ahead of the global energy […]
