Characteristics of Non-Polar Bio-oil Produced by Co-pyrolysis of Corn Cobs and Polypropylene using CO_2 as Carrier Gas

In this article the performance study of mustard oil bio-diesel blended with commercially available diesel has been conducted on the single cylinder engine. The bio-diesel was extracted from the mustard oil by transesterification process. The percentage yield of the biodiesel was ≈82%. The extracted bio-diesel was blended with commercially available diesel in different fractions for the study. The performance study and emission analysis were calculated on single cylinder four stroke diesel engine. According to analysis brake specific energy consumption there was decreasedand there is slight increase in brake thermal efficiency. The exhaust analysis showed that there was considerable drop in the engine emission like carbon dioxide, carbon mono oxide and hydrocarbons, resulting in lower smoke opacity. The oxides of nitrogen were present at a higher percentage in the engine emissions when the bio-diesel blend was used.

“…The depletion of fossil fuel resources i.e. petroleum has attracted the attention of the research to shift to the renewable and biodegradable source [4][5][6][7] . Approximately 85 % of metalworking fluids (MWFs) in industrial applications have been derived from petroleum-based oil which are due to their good lubrication capacity and high stability with a significant long lifetime 8) .…”

As machining operation is getting crucial, thus nanotechnology has been considered in providing more effective performance to reduce friction coefficient and wear protection of both workpiece and tool. This study investigated effect of an inclusion of solid nanoparticle additives such hexagonal boron nitride (hBN), graphene, copper oxide (CuO) at 0.05 wt.% concentration in modified jatropha (MJO) based oil. The performance of nanofluids was evaluated by conducting friction and wear test via four-ball test as well as machining process through orthogonal cutting process. The attained results were then compared with synthetic ester. This present study revealed the MJO nanofluids (MJO + 0.05 wt.% hBN, MJO + 0.05 wt.% graphene and MJO + 0.05 wt.% CuO) showed higher lubrication performance as compared to the commercial synthetic ester in term of physical properties and tribological behaviour. This condition resulted in the excellent machining performance which was explained by the reduction in maximum cutting temperature, chip thickness, effect of morphology chip and tool-chip contact length. Therefore, the MJO nanofluids can be considered as a potential sustainable metalworking fluid to replace the usage of the currently used synthetic ester in machining operation.

“…The ultimate goal of producing syngas is to use it as fuel for power generation or feedstock for chemical synthesis. This may only be achieved through proper cleaning of the gas to remove the tar and capture the CO2 32,33) . The paper gives an overview of the different pathways and the mechanisms involved in removing both tar and CO2 according to past literature and further provides the potential application of the captured carbon.…”

An Outlook on Tar Abatement, Carbon Capture and its Utilization for a Clean Gasification Process

et al. 2021

The generation of syngas via gasification is accompanied by greenhouse gas emissions and certain impurities like tar. This is the major problem that makes the technology unattractive for commercialisation. Tar content present in the syngas limits its application as it causes damage to engines, while the CO2 that accompanies it adds to the climate issues when released to the atmosphere. In this short review, an overview of techniques used for tar abatement, CO2 capturing, and potential areas of CO2 utilisation were discussed.
