An apparatus and method of high pressure treatment of bulk material by extraction and/or impregnation may involve treating bulk material in an internal volume of a pressure vessel apparatus at a high pressure level in a range from 40 to 1000 bar under isolation from the environment. The high pressure treatment may be performed charge-wise in a closed system in the pressure vessel apparatus in that the bulk material is supplied charge-wise to the internal volume with the pressure vessel apparatus closed and is positioned in at least one treatment plane. Upon completion of the high pressure treatment, the bulk material is discharged charge-wise from the internal volume with the pressure vessel apparatus closed. This also gives advantages in terms of handling, especially also with regard to material flow, and with regard to operational reliability.

An apparatus and method for high pressure treatment of bulk material by extraction and/or impregnation may involve high pressure treating bulk material in a high pressure treatment volume of a pressure vessel apparatus at a high pressure level, especially high pressure in the range from 40 to 1000 bar. The method comprises at least the three following step sequences that are each controllable individually: pressurization, high pressure treatment, and depressurization. The high pressure treatment is performed in a continuous manner in the high pressure treatment volume. The high pressure treatment volume or the entire pressure vessel apparatus is in a fixed arrangement during the high pressure treatment. The continuity of the high pressure treatment is ensured solely by means of the high pressure treatment volume. This especially enables engineering optimization of high pressure treatment processes, for example extraction.

Systems and methods are provided for direct conversion of methane and/or ethane to methanol. The methods can include exposing methane to an oxidant, such as O.sub.2, in a solvent at conditions that are supercritical for the solvent while having a temperature of 310° C. or less, or about 300° C. or less, or about 290° C. or less. The solvent can correspond to an electron donor solvent that, when in a supercritical state, can complex with O.sub.2. By forming a complex with the O.sub.2, the supercritical electron donor solvent can facilitate conversion of alkane to methanol at short residence times while reducing or minimizing further oxidation of the methanol to other products.
