The fundamental mechanism(s) for high oven-wall pressure are still not completely understood. The hypothesis put forward in this series of papers is that bubble-growth combined with a lack of bubble-coalescence in the plastic-layer is the primary reason for high oven-wall pressure, and that a lack of bubble-coalescence occurs when the minimum viscosity and elasticity are above a certain threshold...
The addition of biomass to coking coals can reduce operational costs and carbon emissions but also reduces fluidity development. The use of heating rates up to 20 °C min −1 in the softening stage of coal has been investigated using high-temperature small-amplitude oscillatory-shear (SAOS) rheometry to improve the fluid characteristics of binary blends of two coking coals with Scots pine. The...
