Summary: Dewatering biomass is an important step in feedstock pretreatment for biomass power plants due to the negative impact of high moisture on boiler system efficiency and output stability. This study used a steel ball as a spherical heat carrier and investigated the effects of temperature on the dewatering process of different biomasses. Results showed that the moisture content was effectively reduced and the combustion performance of the biomass was significantly improved. This work could provide an economically feasible approach for biomass drying in future studies.

Summary: This study investigates the viability of waste oyster shell powder (OSP) and industrial by-product blast furnace slag (BFS) as cement replacements in sustainable concrete. The experimental results show that OSP and BFS reduce the working performance, compressive strength, and cumulative heat of hydration of the mortar. However, the later stage pozzolanic reaction of BFS significantly increases the compressive strength. The addition of BFS also considerably increases the surface resistivity of the mortar.

Summary: The feasibility of converting high-iron electric furnace ferronickel slag and high-calcium blast furnace ferronickel slag to refractory materials was assessed. The addition of sintered magnesia was found to suppress the negative effects of FeO and CaO in the slag, resulting in the formation of refractory materials. The refractory material derived from EFFS showed higher refractoriness, lower bulk density, and larger compressive strength compared to that derived from BFFS.

Summary: This paper studied the workability, mechanical properties, and hydration characteristics of alkali-activated phosphorus slag-granulated blast furnace slag (AAPG) by mixing phosphorus slag with granulated blast furnace slag. The results showed that the addition of granulated blast furnace slag improved the fluidity and early strength of AAPG, but excessive content led to flash setting of the slurry. The hydration products of AAPG were mainly C-S-H and C-(N)-A-S-H, with some hydrotalcite by-products, but exhibited uneven distribution.

Summary: This study found that TDC showed notable catalytic capability due to the abundant acid sites on its surface, improving BTEX yield by 2.4 times compared to the uncatalyzed case. The loading of additional Zinc increased the acid sites on TDC and further improved catalytic performance. Increasing catalytic temperature and catalyst-to-tire ratio favored the formation of BTEX, but also caused undesirable consequences such as mass loss of tire pyrolysis oil and formation of polycyclic aromatic hydrocarbons.
