New technologies to valorize refuse-derived fuels (RDFs) will be required in the near future due to emerging trends of (1) the cement industry’s demands for high-quality alternative fuels and (2) the decreasing calorific value of the fuels derived from municipal solid waste (MSW) and currently used in cement/incineration plants. Low-temperature pyrolysis can increase the calorific value ...
When biomass is thermochemically processed, the size of the biomass particles affects processing time requirements and yields. This study investigates the effects of particle size at the centimeter scale on pyrolysis through both experimental and modeling approaches, with three types of woody biomass; poplar, pine sapwood, and pine heartwood. Large (D = 3.81 cm) and small (D = 2.54 cm) wood ...

Abstract Loy Yang lignite was pyrolyzed under nitrogen atmosphere in a tube furnace. The changes in physicochemical properties during low-temperature pyrolysis process and their effects on water re-adsorption capacity were investigated. All the samples were characterized by X-ray photoelectron spectroscopy, zeta potential, N2 adsorption–desorption analyzer, and scanning electron microscopy.

We report a novel method for the synthesis of carbon nanotubes: low temperature solid pyrolysis. By pyrolysis of hexamethyldisilazane-derived silicon carbonitride powders in a graphite furnace, we synthesized carbon nanotubes at 1400 °C.
Biomass low temperature pyrolysis is a thermo-chemical treatment method that is earmarked by an pyrolysis temperature ranging from 200ºC to 300ºC (under anoxic, heating rates≦50ºC /min).This ...
Pyrolysis of ligno-cellulosic biomass is a very complex process of interdependent reactions. Nevertheless, it can be reduced to a simple kinetic model. [3] The yield of main products: liquid, char and gas depends especially on the pyrolysis temperature. At high temperatures liquid products are obtained, lower temperatures favour high char ...

Pyrolysis of biomass is a thermal degradation process in the absence of oxygen, producing gas, tar, and char. The product distribution depends on pyrolysis conditions (heating rate, peak temperature, particle size). In this work, the decomposition of dried poplar wood cylinders of 1.9 cm diameter is investigated under conditions favoring production of "biochar" for soil amendment, that is ...
The co-pyrolysis of coffee grounds and polypropylene was studied, at different volumetric fractions of each material, in a fixed bed, under inert flow. With a constant heating rate of 5 °C/min, a preset pyrolysis temperature, between 360 and 420 °C, was maintained for 3 h. Polymer degradation is not completed at a low temperature (360 °C), while coffee is easier to degrade, as confirmed by ...
The formation of condensed ring polycyclic aromatic hydrocarbons (PAHs) from the pyrolysis of ground tobacco in helium over the temperature range of 350-600 degrees C was investigated. PAH yields in the ng/g range were detected and the maximum yields of all PAHs studied including benzo[a]pyrene (B[a …

The main result of the one-stage pre-treatment procedure was the number of micropores. The two-stage, low-temperature pyrolysis procedure focused on the volume of the pores. Carbonized sunflower straw, with pretreated and low-temperature pyrolysis procedures, was judged to be a highly effective and economic method to prepare carbon adsorbents.
