WebApr 1, 2024 · Similar to high-pressure pyrolysis, hydrogenation and viscosity breaking processes also require a certain pressure to achieve better fuel quality. In the hydrogenation process of polyethylene, the increasing hydrogen pressure helped increase light components and reduce the viscosity of produced oil [32]. WebThe molecular weight continues to rise over an Al/Ti ratio of 2.0, however, the weight average remains constant. The Ziegler process produced a high-density polyethylene at pressures as low as atmospheric pressure. High-density polyethylene is a more durable polymer when compared to low-density polyethylene due to its lower degree of branching.

WebBy increasing the concentration of the polymer in the reactor, the overall energy efficiency of the production process is optimised as follows: high pressure polyethylene process – in the high pressure polyethylene process this is achieved by maximising heat transfer.
