“…As a consequence, products such as pyrolysis gas (composed of CO 2 , H 2 , CO, and CH 4 ), bio-oil (mostly oxygenic organic compounds) and bio-char can be obtained, while pollutants such as nitrogen compounds and polycyclic aromatic hydrocarbons (PAHs) are released during pyrolysis process [3][4][5][6]. It is reported that approximately 80% of the unprocessed biomass can be converted into useful pyrolysis products under optimized reaction circumstances [7].…”

“…Thangalazhy-Gopakumar et al [21] investigated catalytic pyrolysis of pine wood using H + ZSM-5 in hydrogen-rich environment by Py-GC/MS; Greenhalf et al [6], used Py-GC/MS to characterize and compare fast pyrolysis product yield from straw, high yielding perennial grasses and hardwoods; Du et al [4] carried out catalytic pyrolysis of three major components (carbohydrates, proteins, and lipids) via Py-GC/MS to better understand the pyrolysis of microalgae. Py-GC/MS also could provide highly efficient sample injection [22][23][24][25].…”

Pyrolysis-gas chromatographic mass spectrometry (Py-GC/MS) was used to determine the yield and chemical composition of the pyrolysis products of Schizochytrium limacinum. The pyrolysis was carried out by varying the temperature from 300 °C to 800 °C. It was found that the main decomposition temperature of Schizochytrium limacinum was 428.16 °C, at which up to 66.5% of the mass was lost. A further 18.7% mass loss then occurred in a relatively slow pace until 760.2 °C due to complete decomposition of the ash content of Schizochytrium limacinum. The pyrolysis of Schizochytrium limacinum at 700 °C produced the maximum yield (67.7%) of pyrolysis products compared to 61.2% at 400 °C. While pollutants released at 700 °C (12.3%) was much higher than that of 400 °C (2.1%). Higher temperature will lead to more pollutant (nitrogen compounds and PAHs) release, OPEN ACCESSEnergies 2013, 6 3340 which is harmful to the environment. Considering the reasonably high yield and minimum release of pollutants, a lower pyrolysis temperature (400 °C) was found to be optimum for producing biofuel from Schizochytrium limacinum.

“…Evaluation of the precipitated solid phase determined that the solids consisted of 11.2% nitrogen by mass (corresponding to a 70% crude protein content based on 6.25 factor) (Du et al, 2013). Due to the high estimated protein content of this solid phase, this protein fraction has potential as a feed material for aquaculture and for agricultural applications.…”

Microwave pyrolysis of lignocellulosic biomass––a contribution to power Africa

Worldwide efforts are being made to increase the use of renewable energy in order to reduce the emission of greenhouse gases. Africa is blessed with abundant resources of fossil fuels as well as renewable energy resources. Yet the continent, especially sub-Saharan Africa, is afflicted with power crisis. For example, in Nigeria, erratic electricity supplies will persist unless the government diversifies her energy sources and adopt new technologies available in the electricity generation sector. International Renewable Energy Agency (IRENA) has called for promotion of increased utilization of the continent's vast renewable energy resources to accelerate development. This review examines the perspective of renewable energy from biomass as an important strategy for a sustainable development in Nigeria. The paper also addresses the use of pyrolysis technology--an efficient thermo-chemical process for energy applications. However, the study presents on applications either to replace fossil fuel in an existing diesel engine-based power generation system or to generate electricity using a gas engine. The work also presented herein addresses the use of industrial-and non-industrial-derived biomass residues for energy purposes with specific example on solid palm oil residues in Nigeria. The current status of pyrolysis technology and its potential for commercial application for bio-fuel production using microwave-assisted pyrolysis in Nigeria are presented. This study will extensively review the recent work on microwave-assisted technology applied to the pyrolysis process. It is estimated that electrical power generation potential at about 500 MW can be obtained by using only the available residues from oil palm industry in Nigeria. This potential can be increased 10-fold with more emphasis on expansion and modernization of oil palm industry in Nigeria. This will benefit in terms of higher revenue from the palm oil export as well as higher renewable energy generation from its biomass residue using the microwave-assisted pyrolysis technology.
