Determination of Effective Conditions for Two-Stage Coprocessing of Coal with Waste Plastics and Petroleum Resid

摘要

Two-stage coprocessing of waste plastics with coal and petroleum resid was investigated using a one-third fractional factorial design. In the two-stage process, waste plastics were reacted in the first stage, and the liquid products from the first stage were then introduced into the second stage, which consisted of coal and petroleum resid. Four factors, each with three levels, were evaluated in the study, namely the catalyst type, the resid type, the plastic type, the plastic type, and the weight percent of coal.
