The fuel type not only influences the engine power and exhaust emissions, but dilutes lubricating oil. We studied effects of biomass fast pyrolysis fuel, or biofuel, on tribological behaviour a fully formulated oil (FFEO) used for heavy-duty diesel engines by reciprocating sliding tribometer, which simulated conditions an cylinder liner piston ring. analysed surface morphology, roughness, eleme...

Chars produced from the pyrolysis of different waste materials have been investigated in terms of their use as a catalyst for the catalytic cracking of biomass pyrolysis gases during the two-stage pyrolysis-gasification of biomass. The chars were produced from the pyrolysis of waste tyres, refused derived fuel and biomass in the form of date stones. The results showed that the hydrocarbon tar y...

The exponential increase of plastic production produces 100 million tonnes of waste plastics annually which could be converted into hydrocarbon fuels in a thermal cracking process called pyrolysis. In this research work, a direct current (DC) thermal plasma circuit is designed and used for conversion of low density polyethylene (LDPE) into diesel oil in a laboratory scale pyrolysis reactor. The...

Pyrolysis/supersonic jet expansion/118.2 nm photoionization TOF mass spectrometry is used to examine competitive thermal dissociations of a deuterated analogue of the title compound, a potential antiknock additive for motor fuel. At high temperatures neutral (CH3)3CC(CD3)2OCH3 (

The depletion of fossil fuels has led to a search for new methods fuel and chemical production from biomass. One the converting biomass into valuable products is process pyrolysis. This been extensively researched in recent years due rising prices energy chemicals. work contains basic information on pyrolysis concerning individual components present types used process. Particular attention was ...

Meat-and-bone-meal (MBM) produced from animal waste has become an increasingly important residual fraction needing management. As biodegradable waste is routed away from landfills, thermo-chemical treatments of MBM are considered promising solution for the future. Pyrolysis and gasification of MBM were assessed based on data from three experimental lab and pilot-scale plants. Energy balances we...

Production of renewable commodity chemicals from bio-oil derived from fast pyrolysis of biomass has received considerable interests, but hindered by the presence of innumerable components in bio-oil. In present work, we proposed and experimentally demonstrated an innovative approach combining atmospheric distillation of bio-oil with co-pyrolysis for mass production of renewable chemicals from b...

The gasification and combustion of dry tree leaves and the cogasification of dry tree leaves soaking crude glycerol were studied experimentally. An updraft fixed bed gasification and combustion system was built. The operation was conducted at different air to fuel ratios. Results show more stable combustion and more effective heat transfer to furnace walls for the cases when tree leaves flakes ...

Crude bio-oil from pine chip fast pyrolysis was upgraded with olefins (1-octene, cyclohexene, 1,7-octadiene, and 2,4,4-trimethylpentene) plus 1-butanol (iso-butanol, t-butanol and ethanol) at 120 °C using a silica sulfuric acid (SSA) catalyst that possesses a good catalytic activity and stability. Gas chromatography-mass spectrometry (GC-MS), Fourier transform infrared spectroscopy (FT-IR) and ...
