Pyrolysis oil, sometimes also known as biocrude or bio-oil, is a synthetic fuel with few industrial applications and under investigation as substitute for petroleum. It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C (900 °F) with subsequent cooling, separation from the aqueous phase and other ...

2013年1月1日 · Pyrolysis oil (Py-oil) or bio-oil represent the second generation of biofuels that exhibit remarkable carbon fixation from biomass, for production of fuels and other value-added products (Fig. 1). A four-to-seven-fold increase in energy content is achieved through conversion of wood biomass to bio-oils [10] .

Light grade py oil is the focus for many in the chemical markets as it yields the most chem feedstocks and blendstocks that can help companies achieve their ESG goals. The label of “py” does not assign it as a fossil-free product.

2018年11月1日 · Pyrolysis oil (py-oil) produced via the pyrolysis of waste biomass is an alternative sustainable source of both bioenergy and valuable biochemical. Py-oil produced from woody biomass typically has water content between 15 and 30 wt%, a heating value between 16 and 19 MJ/kg and high acidity, limiting application as a fuel.

摘要 通过废生物质热解生产的热解油（py-oil）是生物能源和有价值的生化产品的替代可持续来源。 由木质生物质生产的 Py-油通常含水量在 15 到 30 重量％之间，热值在 16 到 19 MJ/kg 之间，酸度高，限制了作为燃料的应用。

What is pyrolysis oil? Pyrolysis oil is a liquid substance obtained during subsequent cooling in the pyrolysis process. It is a complex blend of molecules usually consisting of more than 200 different compounds resulting from the depolymerization of products treated in pyrolysis.

For the bio-oil plant technical and economic analysis, the process is based on fast pyrolysis, which is composed of five major processing areas: feed handling and drying, pyrolysis, char combustion, product recovery, and steam generation.

2023年2月9日 · In this study, we analyzed and critically evaluated whether oil obtained from the non-catalytic pyrolysis of virgin polypropylene (PP) can be used as a feedstock for naphtha crackers to produce olefins, and subsequently polyolefins, without undermining the circular economy and resource efficiency.

Global Petrochemical is committed to realizing the plastics circular economy. They have contracted to purchase large quantities of raw, untreated pyrolysis oil (Pyoil) from an increasing number of pyrolyzer units that transform sorted plastic waste to hydrocarbon liquids at high temperatures in the absence of oxygen.

This study focused on the effects of emulsifier types, hydrophilic-lipophilic balance (HLB), storing time, emulsifying temperature, py-oil percentage, and amount of emulsifier on emulsification characteristics of py-oil and diesel.
