    摘要： Methods are provided for separating algae from an aqueous environment. An aqueous feed containing algae can be aged for a period of at least about 90 hours without purging or other aeration. The aging of the aqueous feed can result in formation of aggregated algae, which can then be filtered under pressure. Due to the larger size of the algae aggregates, the pressurized filtration can reduce/minimize the tendency to clog the filter, as the algae aggregates can generally be too large to fit within the pores of the filter. The filter can preferably be located at the bottom of the vessel holding the aqueous feed. This can assist in allowing the algae to remain in a cake above the filter, as opposed to having the algae dissolve back into the aqueous feed.

    摘要翻译： 提供了从水性环境中分离藻类的方法。 包含藻类的含水饲料可以老化至少约90小时，而不需要吹扫或其他通气。 水性饲料的老化可导致聚集的藻类的形成，然后可以在压力下过滤。 由于藻类聚集体的尺寸较大，加压过滤可以减少/最小化堵塞过滤器的趋势，因为藻类聚集体通常可能太大而不适合于过滤器的孔内。 过滤器可以优选地位于容纳含水进料的容器的底部。 这可以帮助允许藻类保留在过滤器上方的蛋糕中，而不是使藻类溶解回到水性饲料中。

    摘要： A novel composition is provided that incorporates the residual solids from solvent deasphalting to make a high value asphalt product. A process for making the asphalt composition is also provided. A first portion of heavy oil or another feedstock can be deasphalted using propane deasphalting or another suitable deasphalting process. This generates a solvated fraction and an insoluble deasphalting residue. The deasphalting residue is then added to a second portion of heavy oil, such as a second portion of the same type of heavy oil that was used as feedstock in the solvent deasphalting. The mixture of deasphalting residue and heavy oil results in a novel dispersion that is suitable for use as an asphalt. Optionally, an additive such as an alkyl substituted aromatic sulfonic acid can be added to the composition to further improve the asphalt properties.

    摘要： Provided are oil-in-water and water-in-oil emulsion compositions including from 0.01 to 5 wt % of a halogenated elastomer emulsifier, and optionally from to 0.5 wt % of a polyalkylene amine co-emulsifier. The emulsion compositions disclosed herein provide for increased interfacial elasticity and decreased interfacial tension at the oil-water interface to increase resistance to coalescence of dispersed water droplets of a water-in-oil emulsion or oil droplets of an oil-in-water emulsion. The emulsion compositions disclosed herein are suitable for lubricant applications due to their resistance to shear thinning.

    摘要： A delayed coking process for making substantially free-flowing coke, preferably shot coke. A coker feedstock, such as a vacuum residuum, is heated in a heating zone to coking temperatures then conducted to a coking zone wherein volatiles are collected overhead and coke is formed. At least one polymeric additive is added to the feedstock prior to it being heated in the heating zone, prior to its being conducted to the coking zone, or both.
