Abstract: Rigid porous polymeric carbon sorbents, including particularly polymeric carbon sorbents for CO2 capture for flue gas from power plants and for gases from other post combustion CO2 emission outlets, and methods of making and using same. The porous carbon material can be prepared by heating plastic with an additive. The additive can be selected from metal hydroxide, metal oxalate, metal acetate, metal acetylacetonoate or mixtures thereof. By controlling the preparation, such as the temperature of preparation, the porous carbon sorbent can be controlled to be rigid.

Abstract: Methods for the synthesis of graphene, and more particularly the method of synthesizing graphene by flash Joule heating (FJH). Such methods can be used to synthesize turbostratic graphene (including low-defect turbostratic graphene) in bulk quantities. Such methods can further be used to synthesize composite materials and 2D materials.

Abstract: Embodiments of methods for converting gas condensate into a product stream comprising propylene comprise feeding gas condensate at a top region of a downflow high severity fluidized catalytic cracking reactor (HSFCC), where the gas condensate comprises: at least 50% by weight paraffins, and less than 0.1% by weight olefins. The method further comprises feeding catalyst to the top region of the downflow HSFCC reactor in an amount characterized by a catalyst to gas condensate weight ratio of about 5:1 to about 40:1, where the catalyst comprises nano-ZSM-5 zeolite catalyst having an average particle diameter from 0.01 to 0.2 ?m, a Si/Al molar ratio from 20 to 40, and a surface area of at least 20 cm2/g. The method further comprises cracking the gas condensate in the presence of the catalyst at a reaction temperature of about 500° C. to about 700° C. to produce the product stream comprising propylene.
