METHODS OF MAKING CARBON FIBER FROM ASPHALTENES

摘要

Making carbon fiber from asphaltenes obtained through heavy oil upgrading. In more detail, carbon fiber is made from asphaltenes obtained from heavy oil feedstocks undergoing upgrading in a continuous coking reactor.

主权项

1. A method of making carbon fibers from asphaltenes obtained from heavy oil upgrading, the method comprising:
removing a liquid-phase asphaltene stream from a continuous coking reactor; introducing the liquid-phase asphaltene stream through a filter to yield a purified asphaltene stream; introducing the purified asphaltene stream through a spinneret to yield carbon-based filaments; passing the carbon-based filaments through an inert gas stream to yield a carbon-based fiber; and collecting the carbon-based fiber on a draw-down device.
