  • Publication number: 20140274659
    Abstract: Adsorbed natural gas (ANG) technology is an energy efficient approach for storing NG at room temperature and low pressure. ANG technology can be applied to several aspects of the NG industry. The usage of an adsorbent material in natural gas storage and transport may provide increased storage density of NG at a given pressure and decreased pressure of gaseous fuel at a given gas density. Such adsorbent materials have been shown to store substantial quantities of natural gas at relatively modest pressures. Because lower-pressure vessels can be far less expensive than comparable sized high-pressure vessels, ANG based storage can be used to lower the cost of storing natural gas in various applications.

Devices including the molecularly imprinted carbon and their use in methods of detecting analytes are also described. As an example, dibutyl butylphosphonate (DBBP), a surrogate for chemical warfare agents, was used as a template molecule. Electrospun molecularly imprinted SU-8 and pyrolyzed polymer (PP) solid-phase microextraction (SPME) devices were prepared; their ability to preferentially extract DBBP from an aqueous matrix, with and without interferences present, was evaluated via comparison with non-imprinted SU-8 and PP SPME fibers. The electrospun devices demonstrated a higher selectivity for DBBP, as evidenced by their extraction time profiles.

  • Patent number: 7737083
    Abstract: The invention concerns high performance adsorbents based on activated carbon of high microporosity which are present in the form of discrete grains of activated carbon, preferably in spherical form, and which are characterized by the following parameters: a Gurvich total pore volume of at least 0.7 cm3/g, at least 70% of this total pore volume being formed by micropores having pore diameters of ?20 ?, a measure of central tendency pore diameter of not more than 30 ?, and a BET surface area of at least 1500 m2/g. These high performance adsorbents are particularly useful for the adsorption of toxins, noxiants and odors, in particular from gas or to be more precise air streams, for purifying or cleaning gases, such as in particular air, for application in medicine or to be more precise pharmacy and as sorptive storage media for gases, in particular hydrogen.

  • Patent number: 7704921
    Abstract: A gas mixture preheated to high temperatures using an oxy-fuel, an oxygen-enriched air-fuel or an air-fuel burner is used to devolatilize and partially oxidize carbonaceous feedstock, thereby producing an active residual char that can be used in applications utilizing activated carbon. Use of hot gas and ground carbonaceous feedstock allows the equipment to be minimized, thereby allowing the activated carbon to be produced at or near points of use, for example the production of activated char at or near utility boilers for use in the reduction of mercury emissions from flue gas streams.

  • Patent number: 7678738
    Abstract: A method for treating saturated activated coke comprises the following steps: A) The saturated activated coke is subjected to a dehydration treatment so that the water content in the activated coke is ?25%; B) The product obtained from step A is dried at a starting temperature of 120° C.-150° C.; C) The product obtained from step B is subjected to dry distillation and the condition of the dry distillation is that: by heating to a final temperature for the drying of 500° C.-600° C. at a speed of 4° C.-10° C./min and maintaining for 10-60 minutes, the organics adsorbed on the surface and in the pores of the activated coke is cracked, volatilized and carbonized; D) The product obtained from step C is activated and the activation condition is that: after heating to 800° C.-950° C. at 2° C.-8° C./min, a stream is supplied, wherein the weight ratio of the activated coke to the stream is 1:0.5-5 and the activation time is 0.5-2 h. The activated coke after several times of treatment can be used as the fuel.
