The utilization of biomass bottom ashes in cement system

Journal of Sustainable Architecture and Civil Engineering, 2016
By producing 1 ton of Portland cement clinker in environment releasing about 0.85 tons of CO2: 70% of limestone decarbanization and 30% of electricity and thermal consumption. High specific CO2 emissions results take the responsibility of Portland cement industry for about 5% of global CO2 emissions.

Precision Synthesis of Biomass‐Derived Graphene‐Like Carbon With Tailored Crystallinity via Controlled Flash Joule Heating

Carbon Energy, EarlyView.
A dual‐phase flash Joule heating strategy converts pre‐pyrolyzed biomass into structurally tunable carbon materials from waste feedstocks. By decoupling current‐driven thermodynamic input and duration‐dependent kinetic relaxation, the process maps the transition from amorphous carbon to few‐layer turbostratic graphene and turbostratic nanographite ...

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Experimental Investigation on the Effect of Dry and Wet Activation Processes on the Morphological Properties of Activated Carbon Derived From Sugarcane Bagasse

Carbon Innovation, EarlyView.
Synthesis and characterization of sugarcane bagasse‐derived activated carbon via KOH‐assisted dry and wet activation. ABSTRACT This study explores the impact of activation processes on the morphological properties of activated carbon. Carbon is initially produced through vacuum pyrolysis at three temperatures (500°C, 600°C, and 700°C), with a heating ...

Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.
