Gas to olefins processes with coproduction of hydrogen
The present disclosure relates in its first aspect to a process of converting a stream comprising methane into chemicals, said process being remarkable in that it comprises the steps of providing a first stream (1, 5, 11) comprising methane, providing a second stream (79) which is a bromine-rich stream, putting into contact said first stream (15) with said second stream (79) to obtain a third stream (21) comprising at least unreacted methane, methyl bromide, dibromomethane, and hydrogen bromide and removing said dibromomethane from said third stream (21), to produce a dibromomethane stream (103) and a fourth stream (27) comprising unreacted methane, methyl bromide and hydrogen bromide; wherein the fourth stream (27) is converted into chemicals. In its second aspect, the present disclosure concerns an installation for carrying out the process of the first aspect.
METHOD OF IMPROVING AQUEOUS DISPERSIBILITY OF CONDUCTIVE CARBON POWDER, AND METHOD OF PREPARING COLLOID SOLUTION OF CONDUCTIVE CARBON POWDER
The present invention relates to a method of improving aqueous dispersibility of conductive carbon powders, and to a method of preparing a colloid solution of conductive carbon powders. The present invention comprises a step of exposing conductive carbon powders to a plasma jet or reacting same with a plasma-treated reaction gas, wherein the step is characterized by reacting the plasma-treated reaction gas (ionized gas) with the conductive carbon powders, and accordingly by using plasma, the aqueous dispersibility of the conductive carbon powders may be improved in a convenient manner.
Graphite composition, masterbatch comprising same, and graphite composite material embodied thereby
A graphite composition is provided. A graphite composition according to one embodiment of the present invention comprises: a graphite composite in which nanoparticles having a catecholamine layer on the surface thereof are fixed on graphite; and graphite of at least one of graphite flakes, spherical graphite, and expanded graphite. According to this, since the graphite composition has a high dispersibility in a substrate of a different material, a composite material thus realized exhibits a uniform heat dissipation performance and can prevent mechanical strength from deteriorating at a specific position. In addition, since the compatibility with the substrate of a different material is excellent and thus the interface property with the substrate is excellent, the realized composite material can exhibit a further improved heat dissipation performance and mechanical strength. Furthermore, it is very easy to form shapes during injection/extrusion molding in combination with a substrate, and molding into complicated shapes is also possible.

Paper ball-like graphene microsphere, composite material thereof, and preparation method therefor
The present invention provides a paper ball-like graphene microsphere, a composite material thereof, and a preparation method therefor. Such paper ball-like graphene microspheres are obtained by chemically reducing graphene oxide microspheres to slowly remove oxygen-containing functional groups on the surface of the graphene oxide to avoid the volume expansion caused by rapid removal of the groups, thereby maintaining a tight bond between graphene sheets without separation; and removing the remaining small number of oxygen-containing functional groups and repairing defect structures in the graphene oxide sheets by means of high temperature treatment, such that the graphene structure becomes perfect at an ultrahigh temperature (2500 to 3000° C.), thereby further improving the bonding ability between the graphene sheets in the microspheres and achieving a dense structure.
