Systems and methods are provided for co-processing of plastic waste in a coking environment or other thermal conversion environment. The co-processing of plastic waste in a coking environment can be performed by performing four types of processes on the plastic waste. The plastic waste can be conditioned by classifying and sizing of the plastic waste to improve the suitability of the plastic waste for co-processing. The conditioned plastic waste particles can be entrained and/or dissolved into a solvent and/or the base feed. The solution and/or slurry of plastic waste can be passed into a coking environment, such as a fluidized coking environment or a delayed coking environment. The plastic waste can then be co-processed in the coking environment to generate liquid product.

A process for fracturing and devolatilizing coal particles rapidly exposes coal particles to a high temperature, oxygen-depleted work zone for a sufficient time period to cause volatile matter within the coal particles to vaporize and fracture the coal particles. The work zone has a temperature in the range from 600° C. to 2000° C. The coal particles are exposed to the high temperature, oxygen-depleted work zone for a time period less than 1 seconds, and preferably less than 0.3 second. The vaporized volatile matter is condensed and recovered as microcarbon particles.
