摘要： Pitch production systems utilizing coal tar or decant oil for coal. or petroleum based pitch are disclosed. Total pitch production yields are increased by heat treating distillate fractions from the pitch production process. A heat treatment system and process are disclosed in embodiments. The heaviest distillates having the highest molecular weights are subjected to heat treatment, though other embodiments contemplate heat treating a variety of combined distillate fractions. The heat treatment systems require heat soaking the distillate(s) at elevated temperatures of 459-535° C. at a near-constant temperature with near-uniform flow. A fraction of the heat-treated distillate may be reintroduced to the pitch production system as part of a continuous process.

摘要： An end post gap fill assembly for an insulated rail joint includes a gap fill member including a head section at a first end of the gap fill member and a stem section extending from the head section to a second end of the gap fill member. The head section is configured to be positioned between respective head portions of first and second rails and the stem section is configured to be positioned between respective web portions and base portions of the first and second rails. A thickness of the gap fill member is consistent from the first end of the gap fill member to the second end of the gap fill member. A sealant is configured to fill a circumferential gap between an outer surface of the gap fill member and outer surfaces of the first and second rails.

摘要： A rail joint bar includes a body having a first end, a second end positioned opposite from the first end, a first side, a second side positioned opposite from the first side, a top portion positioned between the first and second sides, and a bottom portion positioned between the first and second sides and positioned opposite from the top portion. The body having a first section adjacent to the first end of the body, a second section adjacent to the second end of the body, and an intermediate section positioned between the first section and the second section. The second side of the body includes a first protrusion and a second protrusion spaced from the first protrusion, with a width of the first protrusion at the intermediate section of the body larger than a width of the first protrusion at the first and second sections of the body.

摘要： Pitch products produced by systems and processes utilizing coal tar or decant oil for coal or petroleum based pitch are disclosed. Total pitch production yields are increased by heat treating distillate fractions from the pitch production process. A heat treatment system, process and products produced thereby are disclosed. The heaviest distillates having the highest molecular weights are subjected to heat treatment, though other embodiments contemplate heat treating a variety of combined distillate fractions. The heat treatment systems require heat soaking the distillate(s) at elevated temperatures of 459-535° C. at a near-constant temperature with near-uniform flow. A fraction of the heat-treated distillate may be reintroduced to the pitch production system as part of a continuous process.

摘要： A process and apparatus for the continuous conversion of isotropic carbonaceous materials into anisotropic mesophase pitch is disclosed. The invention disclosed herein addresses the need for lower production costs compared with traditional batch mesophase conversion of isotropic pitch. A unique thermal processing and in-process separation of reacted mesophase from the continuous matrix of fresh or partially reacted isotropic pitch is provided. Potential uses are for further continuous processing into carbon fibers or carbon form densification.
