  • Patent number: 10695722
    Abstract: The present invention relates to a method of preparing a perm-selective porous membrane and a method of separating gases using the prepared porous membrane. According to the present invention, a membrane is synthesized using a hierarchically structured alumina porous support by a counter diffusion method. During this synthesis, the diffusion rate of metal ions loaded on the porous support is controlled by controlling the pore size of the porous support, and the position at which the membrane is synthesized is controlled by synthesizing the membrane inside the support. This can increase the physical stability of the membrane and make the membrane thicker so as to ensure higher H2/CO2 separation factors.

  • Patent number: 9394220
    Abstract: The present invention describes a process and system of producing methanol from methanol condensates. In a preferred embodiment the condensates are biomethanol condensates from chemical pulp mills and various waste sources used to produce a purified biomethanol. Pulp condensates are rich in methanol and contain many other contaminants. Presently, most chemical pulp mills, such as Kraft pulp mills use steam stripping to remove and concentrate the methanol and burn the methanol onsite along with the contaminants. A combination of treatments that include air stripping, steam stripping, distillation and reverse osmosis is described to obtain purified biomethanol suitable for sale or use on site.

More specifically, the methods of the invention comprise modifying plant cells that express farnesene to convert the farnesene to farnesol, and in some cases, to farnesol glycoside, such as farnesol glucoside. In other embodiments, carbon flux is shunted towards sesquiterpene production by applying certain plant growth regulators and herbicides to increase sesquiterpene production.

  • Patent number: 8816137
    Abstract: The invention provides for a method for processing heavy oil from any sources including tar sands, oil shales, varied residues in a bi-reforming process utilizing reaction conditions with steam and carbon dioxide sufficient to form a mixture of hydrogen and carbon monoxide to form methanol. Methanol produced can be dehydrated to form dimethyl ether, with water produced being recycled back to the bi-reforming process.

  • Publication number: 20140221701
    Abstract: An improved process for extracting fusel alcohols and/or fusel alcohol esters from an ethanol fermentation product involves adding to the fermentation product an extractant solvent selected from amyl alcohols, amyl acetates, and mixtures thereof to produce a two-phase system including a water and alcohol phase, and an immiscible second phase comprised of amyl alcohols, amyl acetates or a mixture thereof. Thereafter, the first and second phases can be separated to obtain a first phase depleted of fusel alcohols and/or esters of fusel alcohols and a second phase containing fusel alcohols and/or esters of fusel alcohols extracted from the first phase.

  • Publication number: 20140212941
    Abstract: The present invention provides a biosafety-guarded photobiological butanol production technology based on designer transgenic plants, designer algae, designer blue-green algae (cyanobacteria and oxychlorobacteria), or designer plant cells. The designer photosynthetic organisms are created such that the endogenous photobiological regulation mechanism is tamed, and the reducing power (NADPH) and energy (ATP) acquired from the photosynthetic process are used for synthesis of butanol (CH3CH2CH2CH2OH) directly from carbon dioxide (CO2) and water (H2O). The butanol production methods of the present invention completely eliminate the problem of recalcitrant lignocellulosics by bypassing the bottleneck problem of the biomass technology.

  • Publication number: 20140212940
    Abstract: Mixed matrix pervaporation membranes are described which include i) a matrix phase comprising a polymeric material, and ii) a zeolitic imidazolate framework (ZIF) dispersed in the matrix phase. In membranes described, the thickness of the membrane is greater than 0.5 ?m. The membranes may in examples be used in a process for separating an organic compound from an aqueous liquid mixture. An example process includes contacting the liquid mixture on one side of a mixed matrix pervaporation membrane to cause the organic compound to permeate the mixed matrix membrane, and removing from the other side of the membrane a permeate composition comprising a portion of the organic compound which permeated the membrane. Example membranes described have relatively good selectivity for separation of the organic compound from the liquid mixture.

  • Patent number: 8779209
    Abstract: The present invention provided a method for salting-out extraction of acetone and butanol from a fermentation broth, characterized in that one type, or two or more types of salts and one type, or two or more types of extractants are added to an acetone-butanol-ethanol (ABE) fermentation broth, in which the salt saturation achieves 10%˜100%; and the volume ratio of the fermentation broth containing salts to the extractants is 1:0.1˜1:5. The mixture is allowed to stand until phase separation is formed. The top phase is a solvent phase or extraction phase enriched with acetone and butanol whereas the bottom phase is a salt-enriched phase or raffinate phase. This method involves many advantages, such as the simplified operation procedure, accelerated separation process and low separation cost, and therefore becomes a promising method of separating acetone and butanol in industrial application.
