The quantity of plastic waste generated by the public has increased dramatically over the years. Biomass is an abundant and substantial energy resource found in diverse forms all over the planet. In this regard, the co-pyrolysis of plastic and biomass wastes is an attractive option to mitigate the issue of waste accumulation and viable fuel production. This review focuses on progress in waste disposal and energy generation through co-pyrolysis. The properties of common solid feedstock combinations are addressed with an emphasis on proximate analysis, elemental composition, and heating value. Subsequently, state-of-the-art kinetics is reviewed and compared for the efficacies of various kinetic models, which could be applied to understand decomposition mechanisms. The synergy between biomass and plastics was analyzed, and the impact of decomposition mechanisms on the bio-oil, char, and gas yield and composition was discussed. In addition, this study unveiled various reaction pathways for non-catalytic and catalytic co-pyrolysis. Finally, a summary of the economics in co-pyrolysis with knowledge gaps concerning waste management and energy production is addressed. The main goal of this review is to provide a feasible, practical pathway for clean and effective plastic waste disposal by using biomass waste to increase the synergistic effect.

ABSTRACT The technological evolution of electronic equipment in the field of computers and household appliances, along with shorter life of most items, is creating a great concern for managing this waste stream. The main aim of the present investigation was to convert waste keyboard keys into high-quality pyrolysis oil using a microwave catalytic pyrolysis process. Iron (Fe), Nickel (Ni), were doped in different ratios on Biochar (BC) by wet impregnation method, and it was used as a green catalyst for clean fuel production. Initially, a non-catalytic pyrolysis process was conducted and found a maximum pyrolysis oil yield of 49.6 wt.%. Further, microwave catalytic pyrolysis was conducted with variable amount of metal loading and found that highest oil yield of 61.33 wt.% was achieved using 15%Fe-5%Ni/BC catalyst due to the presence of a higher quantity of iron. The produced pyrolysis oil at this condition consists of 45.07% single-ring compounds and reduced the undesirable polycyclic aromatic hydrocarbons (PAHs) in the pyrolysis oil. This work provides a pathway for preparing green catalysts and safe disposal of electrical and electronic plastic waste with better resource recovery.

Aspen HYSYS simulation of biomass pyrolysis for the production of methanol

In terms of supplying energy carriers for the transport sector and storing electricity outflows from intermittent sources, the importance of renewable fuel production has become significant. In this work, the production of methanol fuel from biomass is simulated. Biomass is an excellent renewable resource for the production of methanol. It is of utmost importance to make effective use of biomass resources. There are different methods available for the production of methanol from biomass. One of the best methods is pyrolysis to convert biomass into methanol. This is due to the fact that pyrolysis is an efficient conversion method compared to other thermochemical conversion practices. Pyrolysis is the process of decomposing biomass in an inert atmosphere to convert it into worthwhile products. The production of methanol from sugarcane bagasse via pyrolysis was simulated using Aspen HYSYS because of its ability to solve chemical as well as energy problems. To simulate the microwave assisted pyrolysis reactor, an Aspen HYSYS model was developed. The model is based on Gibbs free energy and it has been calibrated using the restricted equilibrium method. The model was validated and foresees the percentage of methanol yield, the predicted values very well agreed with the available data. Important parameters of the pyrolysis process such as pyrolysis temperature, sweeping nitrogen gas flow rate, heating rate, biomass moisture content were varied. It was found that pyrolysis temperature, nitrogen flow rate, heating rate have a very profound influence on the pyrolysis process and methanol yield, while the moisture content of biomass had a lesser impact.

Synthesis and characterization study of solid carbon biocatalyst produced from novel biomass char in a microwave pyrolysis

Abstract Biochar is considered to be one of the most significant by-products obtained from biomass pyrolysis. Biochar is of significant importance in soil amendment, catalyst preparation, and activated carbon formation. Microwave pyrolysis is one of the emerging trends in biochar production. Since the residence time in a typical microwave pyrolysis reactor is quite high, biochar is often the major by-product of biomass microwave pyrolysis. Microwave pyrolysis additionally is an extremely energy-efficient method. This present study involves the preparation and characterization of biochar produced from senna pendula seedcake. The biochar produced from the pyrolysis (up to 600 ˚C) is then subjected to sulphonation using fuming sulphuric acid. TG analysis shows that pyrolysis occurred between 200 and 450 ˚C. FTIR analysis results show that upon sulphonation, the biochar has been strongly carbonized. Both FTIR and XRD analyses showed that biochar had been impregnated with carbonyl and sulphonyl groups post sulphonation. SEM micrography results showed that sulphonation had caused a breakdown of existing organic compounds along with an increase in pore diameter.

Study on availability analysis, performance and emission behavior for an oxygen enriched turbocharged diesel engine

Abstract There is an ever-increasing necessity for sustainable energy resources. The restrictions on diesel engines, which were already strict in the previous decade, are only going to increase in the next one. A zero-emission diesel engine has become an absolute necessity. Furthermore, it is critical to increase the thermal efficiency of these engines. Dimethyl Carbonate (DMC) is gaining popularity as an oxygenated additive to diesel due to its desirable boiling point and good solubility. The current work investigates the performance, emission and exergy parameters of a diesel engine with DMC as an additive. Additionally, we also explore the effects of oxygenation at the air side by introducing a turbocharger at the intake manifold. Four different blends of oxygenated additives were analysed with the turbocharger in operation. Here, a 5% blend of DMC produced the most desirable results. When a 5% blend of DMC with diesel was tried out, the brake thermal efficiency increased by 4 percent. At maximum brake mean pressure 4.8 bar, the maximum exergy efficiency was 65%. This blend also has least the brake specific fuel consumption and carbon monoxide emissions. These results emphasize the usage of DMC as an additive, and are of direct relevance to the alternative fuel industry—aiding it in making informed decisions about blending fuel additives.
