Pyrolysis oil, despite its potential as a renewable energy source, faces several significant challenges that hinder its widespread use.
5 Key Challenges You Need to Know
1. Instability and Chemical Reactivity
Pyrolysis oil is composed of intermediate, reactive decomposition products, which makes it inherently unstable.
Over time, it undergoes changes, most notably an increase in viscosity due to condensation reactions of its reactive components.
This aging process can also lead to phase separation, further complicating its storage and use.
Heating the oil to temperatures above 100 °C can cause rapid reactions, leading to the formation of a solid residue and distillate, which are less useful than the original liquid form.
2. Incompatibility with Petroleum Infrastructure
Pyrolysis oil differs significantly from petroleum oils.
It is not miscible with petroleum oils, contains up to 40% oxygen by weight, and has a lower heating value.
It is also acidic, unstable when heated, and denser than water.
These properties make it incompatible with existing petroleum infrastructure, necessitating significant modifications or entirely new systems for its use.
3. Corrosiveness and Low Heating Value
The complex mixture of oxygen functional groups in pyrolysis oil contributes to its highly corrosive nature and low heating value.
These oxygen groups need to be removed through deoxygenation processes, such as catalytic hydrodeoxygenation (HDO).
However, these processes are energy-intensive and require hydrogen, making the overall production of biomass bio-oil less economically viable on an industrial scale.
4. Utilization Challenges
The utilization of pyrolysis oil is challenging due to its complex composition of oxygenated compounds.
While it can potentially substitute conventional fuel oils in stationary applications, its quality parameters need to be carefully defined for each application.
Upgrading pyrolysis oil to a hydrocarbon fuel or using it for chemical and material production requires additional processing, which adds to the complexity and cost.
5. Safety and Environmental Concerns
Pyrolysis processes involve high temperatures and can be hazardous if not properly managed, potentially leading to fires or explosions.
Additionally, the process generates emissions including gases, volatile organic compounds (VOCs), and particulate matter, necessitating effective emission control systems to prevent environmental pollution.
