    Abstract: A hydrophobic admixture, for cementitious materials such as cement paste, mortar, and concrete, includes solid polymer particles with a coating of hydrophobic agent and surfactant. The solid polymer particles adhere to exterior surfaces of hydrated cement particles in the cement matrix. The solid polymer particles deliver the hydrophobic agent into the cement matrix which is hydrophilic. The hydrophobic agents are distributed uniformly throughout the cement matrix. The solid polymer particles can be crumb rubber particles derived from waste rubber tires, recycled plastics and similar solid materials. The hydrophobic liquid agent is derived from waste lubricant oil, spent motor oil, base oil, esters of fatty acids, vegetable oil and the like. Fine particles such as activated carbon, silica fume and spent catalyst can be employed to fill the large pores or cracks that develop in the cementitious matrix. The cured cementitious materials exhibit high contact angles and high compressive strengths.

    Abstract: Extractive distillation for recovering aromatic hydrocarbons employs an extractive distillation column with a novel overhead system including a partial condenser. The process enables (i) efficient removal of heavy non-aromatics, particularly C8 naphthenic compounds, from the EDC bottom stream to increase the purity of aromatic products, especially of the mixed xylenes and (ii) reduction (or better control) of benzene loss to the raffinate product stream to maintain its quality as a gasoline blend stock and, as a result, enhance benzene recovery in the aromatic products. Feedstock includes a full-range feedstock, such as pyrolysis gasoline, or a narrow-range feedstock, such as reformate.

    Abstract: A high capacity magnetic filter separates diamagnetic and/or paramagnetic substances from fluid streams. Diamagnetic solid substances are magnetized under an external magnetic field through coordinated interaction of diamagnetic solid substances with an inducement paramagnetic material (IPM). The magnetic filter serves as a separation zone created by the presence of IPM and magnets that are shielded from the IPM by non-magnetic sleeves or partitions. The IPM in the void volume between the magnets affords large surface area onto which diamagnetic and paramagnetic materials can contact and be attracted to. The relative position and distance of the magnetic source, such a magnetic bar or electromagnet, to the solid mixture of diamagnetic and IPM are adjusted to induce sufficiently strong magnetism in the diamagnetic solids which causes the diamagnetic solids to be attracted by the magnetic field as well. Both diamagnetic and paramagnetic substances can be removed from a liquid or gas.

    Abstract: 一高產能的磁性過濾器,用以分離出液流的反磁性及/或順磁性物質。於外部磁場下,透過反磁性固態物質與誘發性順磁材料(IPM)的協同作用,反磁性固態物質會被磁化。作為分離區的磁性過濾器係由誘發性順磁材料及磁體所建立,其中磁體藉由非磁性套筒或隔板而屏蔽IPM。磁體間隙內的IPM 提供大的表面積,可接觸並吸引反磁性及順磁性物質,調整磁性源如磁棒或電磁體及反磁性固態混合物與IPM間的相對位置及距離,誘發出反磁性固體的磁性,使其足以令反磁性固體亦受到磁場的吸引。因此,能夠移除液體或氣體中的反磁性及順磁性物質。
