Conversion of Polyethylene Blended with VGO to Transportation Fuels by Catalytic Cracking

Current state and future prospects of plastic waste as source of fuel: A review

“…The main components in the product gas were ethane and propene. Compared to the result given by Ng [74], thermal pyrolysis of polymer on a fluidized bed could produce higher degree of cracking (indicated by the ratio of dry gas/LPG) compared to catalytic pyrolysis in a fixed bed reactor. It is important to realize that the temperature profile difference produced distinct effect on the products distribution, especially those from the pyrolysis of VGO oil.…”

“…In order to solve this problem, some researchers look into the possibility of dissolving plastic feed in suitable solvent, followed by pyrolysis of the solution. Ng [74,98] performed catalytic pyrolysis on HDPE resin pellets dissolved in the vacuum gas oil (VGO). The conversion of HDPE was up to 77.4% (for 5 wt% HDPE concentration) and 52.4% (for 10 wt% HDPE concentration) respectively.…”

Catalytic Upgrading of Plastic Wastes

“…The possibility of cofeeding plastic wastes with petroleum cuts such as vacuum gas oil (VGO) [110], Arabian light petroleum residues [111], light cycle oil [84], lube oils [88] or even raw chemicals such as benzene [85] has been widely investigated in the literature. The underlying aim is to reduce the high viscosity of the molten plastics.…”

“…In this way, Ng [110] reported the catalytic cracking of blends made up of vacuum gas oil (VGO) and 5-10 wt% of high-density polyethylene in a fixed bed reactor at 510…”

Liquefaction of Municipal Waste Plastics over Acidic and Nonacidic Catalysts

“…Ng [39] evaluated conversion of HDPE blended with vacuum gasoil (VGO) to transportation fuels by catalytic cracking over an acidic catalyst (KOB-627). It has been shown that addition of HDPE increased the gasoline yields significantly when more than 10% plastics were dissolved in the VGO.…”
