A new product (Application 460B-00) from Agilent Technologies/WassonECE uses a 5973N GC/MSD (gas chromatograph/mass selective detector) for the determination of trace levels of impurities that are moderate-to-low carbon-content such as oxygenates, mercaptans, sulfides, arsine, and phosphine in ethylene and propylene. This work describes the performance of Application 460B-00 with respect to lin...

Research Octane Number (RON), among other autoignition related properties, is a primary indicator of the grade spark-ignition (SI) fuels. However, in many cases, blending various gasoline components affects RON final fuel product nonlinear way. Currently, lack precise predictive models for challenges accurate and production commercial SI This study compares popular Machine Learning (ML) algorit...

Based on available toxicity data, malondialdehyde (MDA; O=CHCH2CH=O) has been designated as a potential human carcinogen. A handful of studies suggest that MDA forms in the gas and aerosol phase troposphere, potentially contributing to inhalation toxicity, yet it never quantified ambient air. The thiobarbituric acid (TBA) assay for (MDA) used marker reactive oxygen species (ROS), oxidative stre...

Second-generation biomass (BM) can be produced in amounts that meet worldwide fuel demands. However, BM favors parallel and undesirable reactions its transformation chain. We circumvent this problem by first modifying ketalization, giving a user-friendly liquid we named BP (bio-petroleum). This study converted representative compound of BP, DX (1,2:3,5-di-O-isopropylidene-α-D-xylofuranose), mix...

To carry out the investigation, a cylinder pressure model was developed based on the position of the crankshaft, engine load, engine speed, and fuel injection time. This model takes into account the maximum number of parameters involved. The accuracy of the model was verified by experimental results. The average error of the cylinder pressure, the average radical of the square of the error of t...
