2021年10月28日 Abstract. Coal and biomass are regularly used in the preparation of activated coke. In this paper, coal and biomass (poplar bark) were co-pyrolyzed, and activated coke was prepared by physical “one-step activation,” followed by ammonization and additional activation by potassium carbonate (K2CO3). The activation temperature

2020年12月30日 Powdered activated coke (PAC) is a good adsorbent of SO2, but its adsorption capacity is affected by many factors in the preparation process. To prepare the PAC with a high SO2 adsorption capacity using JJ-coal under flue gas atmosphere, six parameters (oxygen-coal equivalent ratio, reaction temperature, reaction time, O2

2022年8月18日 The properties of the coke produced from composite/caking coal blending showed that the optimum blending amount depends on the type of caking coal, but high-strength and high-gasification reactivity coke can be produced. Additionally, it was found that 3–15wt-%-biomass could be added as char for coke production.

Dry reforming of methane is gaining great interest owing to the fact that this process efficiently converts two greenhouse gases (CH4 and CO2) into synthesis gas (CO + H2), which can be further processed into liquid fuels and chemicals. Herein, a perovskite-derived nanostructured Ni/La2O3 material is reported as an efficient and stable catalyst for this

Preparation of Coke from Hydrothermally Treated Biomass

Increasing HTT up to 250°C causes the coke yield increase significantly, and this is attributed mainly to removal of HCEL from the biomass. The coke yield further increases at HTT of 250–300°C, but only slightly. HT at 250–260°C increases the gross coke yields from the bamboo, larch and mallee by 21, 29 and 26 wt%-dry-sample, respectively.
