Thermochemical conversion of non-edible biomass offers an efficient and economically process to provide valuable fuels and prepare chemicals derived from biomass in the context of developing countries. Pyrolysis has advantages over other thermochemical conversion techniques because it can convert biomass directly into solid, liquid and gaseous products by thermal decomposition of biomass in the...

Due to serious environmental problem and strict regulations to control pollution, researchers across the globe are putting their effort to find clean, renewable, greener and cost effective method to produce biochemical from biomass. The aim of this article was to highlight the method to extract phenolic compounds from crude pyrolysis oil using switchable hydrophilicity solvents (SHS). The pyrol...

Biomass mainly in the form of wood is the oldest form of energy used by humans. Biomass generally means a relatively dry solid of natural matter that has been specifically grown or has originated as waste or residue from handling such materials. The thermochemical conversion of biomass (pyrolysis, gasification, combustion) is one of the most promising non-nuclear forms of future energy. In the ...

Pesticide is a pollution problem in agriculture. The usage of ZnCr2O4/CNS and H2O2 as additive liquid fertilizer has potency for catalytic pesticide degradation. Colloid condition needed easy spraying. Rice husk sawdust were used carbon precursor ZnCl2 activator. biomass–ZnCl2 mixtures pyrolyzed using microwave (400–800 W, 50 min). products dispersed water by blending then evaporated to obtain ...

This research evaluated the hydrocarbon emission characteristics during pyrolysis of four carbonaceous additives that can be used in green sand foundries. These included a highly volatile bituminous coal, anthracite, lignite and cellulose. The samples were flash pyrolyzed in a Curie-point pyrolyzer at 920 C with a heating rate of about 3000 C/sec. This simulated the fast heating conditions that...

Manure-derived biochar is the solid product resulting from pyrolysis of animal manures. It has considerable potential both to improve soil quality with high levels of nutrients and to reduce contaminants in water and soil. However, the combustible gas produced from manure pyrolysis generally does not provide enough energy to sustain the pyrolysis process. Supplementing this process may be achie...

Polyethylene is probably the most used plastic material in daily life and its accurate analysis is of importance. In this communication the chemical structure of polyethylenes is studied in detail using conventional analytical pyrolysis (Py-GC/MS), bulk stable isotopic analysis (IRMS) and pyrolysis compound specific stable isotopic analysis (Py-CSIA) to measure stable isotope proportions (δ(13)...
