摘要： Methods for producing solid, substantially round, spherical and sintered particles from a slurry of a raw material having an alumina content of greater than about 40 weight percent. The slurry is processed to prepare green pellets which are sintered in a furnace with microwave energy at a temperature of 1480 to 1520° C. to produce solid, substantially round, spherical and sintered particles having an average particle size greater than about 200 microns, a bulk density of greater than about 1.35 g/cm3, and an apparent specific gravity of greater than about 2.60.

摘要： A method for making proppant particles is provided. The method can include providing a slurry of ceramic raw material, the slurry containing a reactant including a polycarboxylic acid, and flowing the slurry through a nozzle in a gas while vibrating the slurry to form droplets. The method can also include receiving the droplets in a vessel containing a liquid having an upper surface in direct contact with the gas, the liquid containing a coagulation agent. The method can further include reacting the reactant with the coagulation agent to cause coagulation of the reactant in the droplets. The droplets can then be transferred from the liquid and dried to form green pellets. The method can include sintering the green pellets in a selected temperature range to form the proppant particles. In one or more exemplary embodiments, the reactant can be or include a PMA:PAA copolymer.
摘要翻译： 提供了制造支撑剂颗粒的方法。 该方法可以包括提供陶瓷原料的浆料，所述浆料含有包含多元羧酸的反应物，并且使浆料在气体中流过喷嘴，同时振动浆料以形成液滴。 该方法还可以包括在容器中容纳液滴，所述容器含有与气体直接接触的上表面的液体，所述液体含有凝结剂。 该方法还可以包括使反应物与凝结剂反应以引起反应物在液滴中的凝结。 然后可以将液滴从液体中转移并干燥以形成生球团。 该方法可以包括在选定的温度范围内烧结生球团矿以形成支撑剂颗粒。 在一个或多个示例性实施方案中，反应物可以是或包括PMA：PAA共聚物。

摘要： Proppant particles formed from slurry droplets and methods of use are disclosed herein. The proppant particles can include a sintered ceramic material and can have a size of about 80 mesh to about 10 mesh and an average largest pore size of less than about 20 microns. The methods of use can include injecting a hydraulic fluid into a subterranean formation at a rate and pressure sufficient to open a fracture therein and injecting a fluid containing a proppant particle into the fracture, the proppant particle including a sintered ceramic material, a size of about 80 mesh to about 10 mesh, and an average largest pore size of less than about 20 microns.
