Abstract

High-throughput production apparatuses, systems, and associated methods may include pneumatic dense phase feeding. For example, a method may involve feeding via pneumatic dense phase feeding a matrix material into a mold cavity to form a desired cross-sectional shape, the matrix material comprising a binder particle and an active particle; heating (e.g., via microwave irradiation) at least a portion of the matrix material so as to bind the matrix material at a plurality of contact points thereby forming a porous mass length, cooling the porous mass length, and cutting the porous mass length radially thereby producing a porous mass. In some instances, the matrix material may include a plurality of active particles, a plurality of binder particles (optionally having a hydrophilic surface modification), and optionally a microwave enhancement additive.

Изобретение, которое иллюстративно описано в данном документе, можно соответствующим образом осуществлять на практике, когда отсутствует какой-либо элемент, который не является определенно описанным здесь, и/или любой необязательный элемент, описанный здесь. Хотя композиции и способы описаны с использованием терминов "включающие", "содержащие" или "имеющие" разнообразные компоненты или стадии, эти композиции и способы могут также "состоять, в основном" или "состоять" из разнообразных компонентов и стадий. Все числа и интервалы, которые описаны выше, могут изменяться в некоторой степени. Когда описывается численный интервал, имеющий нижний предел и верхний предел, считаются определенным образом описанными любые числа и любые включенные интервалы, которые находятся в пределах данного интервала. В частности, каждый интервал значений, описанный здесь (в форме "от около а до около Ъ", или в эквивалентной форме "около от а до Ъ", или в эквивалентной форме "около а-Ъ"), следует понимать как определяющий все числа и интервалы, которые содержит более широкий интервал значений. Кроме того, термины в формуле изобретения имеют свои простые обычные значения, если патентовладелец не устанавливает другие условия четко и определенно. Если возникает какое-либо противоречие в использовании слова или термина в настоящем описании и в одном или нескольких патентах или других документах, которые могут включаться в настоящий документ посредством ссылки, следует принимать определения, которые согласуются с настоящим описанием.illustrative embodiments of the above, you can change, merge or modify, and all such modifications are included in the scope and idea of the invention.

Although the compositions and methods are described using the terms "comprising", "containing" or "having" various components or steps, these compositions and methods may also "consist essentially of" or "consist of" various components and steps. All numbers and intervals that are described above may vary to some extent. When a numerical interval is described, having a lower limit and an upper limit, any numbers and any included intervals that are within a given interval are considered to be described in a certain way. In particular, each range of values described here (in the form “from about a to about b”, or in the equivalent form “about from a to b,” or in the equivalent form “about a-b”) should be understood as defining all numbers and intervals that contains a wider range of values. In addition, the terms in the claims have their simple ordinary meanings, unless the patent owner sets other conditions clearly and definitely. If any contradiction arises in the use of a word or term in the present description and in one or more patents or other documents that may be incorporated by reference in this document, definitions should be adopted that are consistent with this description.
