Methods, compositions, systems and devices are provided in which zeolite particles, preferably of silicon and aluminum, are used as desiccants. In embodiments a plurality of zeolite particles are provided that are less than 1 mm in size. The particles may be arrayed such that at least some of the plurality of particles are spaced apart from each other and may be arrayed in rows and columns. Embodiments provide the particles are useful or removing water under ambient conditions and in removing water from air or material and in an embodiment removing water from plant material, such as harvested crop material, or where the dried air is contacted with plant material. Microwave radiation may be used to efficiently and in a cost effective manner dehydrate the rehydrated particles.

In a system for perorming a multi-step process for selectively purifying various pharmacologically-relevant components of a source plant such as cannabis, an initial step of the process provides a low-temperature, robust process for dehydrating and decarboxylating the starting product—fresh raw cannabis—by means of a vacuum-assisted microwave distillation process. An important by-product of the dehydration/decarboxylation is a terpene-rich distillate. By doing the terpene capture under vacuum, distillation temperature may be kept low. The low distillation temperature maximizes yields of thermally-sensitive components such as terpenes and cannabinoids.

The present invention is directed towards a process for upgrading lignite comprising: prior to production pre-assess the calorific value of the coal, by selecting a relational expression between a calorific value of lignite and a degree of metamorphism, a moisture content and an ash content thereof based on a ratio of the ash content to the moisture content, pre-assess the calorific value of the coal; combining a relational expression between a production cost and the ash content and moisture content to make a cost budget; determining degrees of deashing and drying; selecting and implementing a lignite ash reduction pretreatment process; and implementing dry sorting first and then drying. The upgrading process has high sorting efficiency, high drying efficiency and low production cost, and meets the requirement for the surface moisture of the raw coal in the dry sorting operation.
