Sequential Ammonia and Carbon Dioxide Adsorption on

The amine-rich surfaces of pyrolyzed human solid waste (py-HSW) can be "primed" or "regenerated" with carbon dioxide (CO2) to enhance their adsorption of ammonia (NH3) for use as a soil amendment To better understand the mechanism by which CO2 exposure facilitates NH3 adsorption to py-HSW we artificially enriched a model sorbent pyrolyzed oxidized wood (py-ox wood) with amine

Pellet

Abstract: In the present study catalytic pyrolysis characteristics of corn straw pellet were studied in biomass pyrolysis test bench The effect of content of CaO added in biomass pellet on pyrolysis products was investigated The results showed that: with the increase of CaO content the yield of tar decreased and the yield of char and gas increased Among gas compositions the volume

Drying biomass

Drying biomass Rolling bed dryer WB-T The growing worldwide interest in using biomass as an alternative fuel means that innovative solu-tions are called for New frequently CO 2-neutral energy sources are increasingly competing with conventional fuels for generating heat and elec-tricity Progressive solutions for energy-saving drying of goods are also becoming more and more import-ant

Biomass Dynamic Models

Biomass dynamic models are the simplest stock assessment models that are commonly used Stock-recruitment models are in most cases used only as a part of a complete age-structured assessment Only for semelparous species and in practice only for Pacific salmon can stock-recruitment models be used by themselves to evaluate alternative fishing plans We presented stock-recruitment before
