Benefits of technology

The invention is a method of processing liquid materials using a fluidized catalytic cracker (FCC). The method involves converting biomass and petroleum materials into a liquid starting material, heating it to a high temperature, and obtaining a devolatilized liquid material with reduced volatile components. This devolatilized liquid material then undergoes further processing to produce a volatile components product. The technical effect of this method is to provide a way to produce a high-quality liquid starting material with improved properties for further processing.

Problems solved by technology

This is in stark contrast to slow pyrolysis, which produces a thick, low quality, two-phase tar-aqueous mixture in very low yields.
If the flash point is too low it causes the fuel to be subject to flashing and possible ignition.
As such, a low flash point measurement may unjustifiably classify these liquids in regard to flammability since the measurement is only reflecting the flash point of a small portion of the total product.

Embodiment Construction

[0030]The present disclosure generally relates to the devolatilization of thermally produced liquids to raise the flash point. More specifically, the present disclosure is directed to methods and apparatus to effectively and selectively reduce volatile components of liquids produced from the thermal conversion of biomass and petroleum materials, resulting in an increase in the flash point.

[0031]The measure of flash point of a liquid is a common gauge of the flammability and is indicated by the maximum temperature at which a material can be stored and handled. If the flash point is too low it causes the liquid to be subject to flashing and possible ignition. Certain properties of materials are not generally affected by variations in the flash point, such as auto-ignition temperature, fuel injection and combustion performance. In many jurisdictions, there is a significant difference in how materials are treated if the flash point is below a certain threshold. This threshold is typical...
