Chromatographic Analysis Of The Chemical Composition Of Pyrolysis Distillate, Sh.T. Juraev, B.F. Muxiddinov, U.T. Tailakov
Chemical Technology, Control and Management
The paper presents the results of a study of the physico-chemical characteristics of the liquid fraction of products of thermal oxidative pyrolysis of worn tires. The mass fraction of the volatile gas compounds, the optimal boiling points of the obtained condensates and the flashpoint of pyrolysis liquids, together with the mass composition of cracking products of rubber products at high-temperature pyrolysis at a temperature of 800-900 °C, were determined. Chromatographic analysis allowed us to determine the composition, mainly the mass composition of pyrolysis products, which consisted of carbon (42.8%), higher aliphatic and aromatic hydrocarbons (17.0%), methane (10.2%), benzene (4.2%) and …

Laser direct writing (LDW) is a fast and cost-effective method for printing conductive patterns in flexible polymer substrates. The electrical, chemical, and mechanical properties of polyimide (PI) make it an attractive material choice for laser writing of conductive circuits in such polymer. Electrically insulating PI has shown great potential for flexible printed electronics as LDW enables selective carbonization in the bulk of such material leading to the formation of conductive lines. However, existing studies in this area reveal a few key limitations of this approach including limited conductivity of written structures and fragility of carbonized PI. Therefore, more research is …

Research into the generation of energy from human and animal waste has been primarily focused on gas production (especially methane and hydrogen). While there is some work concentrated on ethanol and biodiesel creation from wastes (fuels used for ground transportation primarily), increasing research interest has been recently directed toward long chain hydrocarbon production for aviation fuels. Kerosene components from swine fecal waste have been generated from four natural sources: undigested dietary lipids, host lipids excreted in feces, bacterial cell walls and products of bacterial fermentation.
