PFRs for running multiphasic processes are disclosed. The PFRs are single or multi-chamber devices having at least three types of regions (a liquid-contacting region, a gas-contacting region and a Ssquid-coSection region), and a porous substrate providing fluid communication at least between the liquid-contacting and gas-contacting regions. Removal of liquid from the porous substrate, such as by collecting the liquid as it flows off the bottom of the porous substrate in the Siquid-coSSection region or such as by evaporation of the liquid from the porous substrate in the evaporation region supports a continuous flow process. Methods of using the PFRs are also disclosed, for example methods of using the PFRs as photobioreactors for cultivating photosynthetic microorganisms, for producing fermentable sugars, for producing ethanol, for fermenting synthesis gas and producing single cell protein from natural gas.

The present disclosure provides methods for hydrothermally treating sewage wastes to preferably obtain valuable products, including fatty acids, carbon-neutral combustible hydrochar fuels, heavy metal salts for recycling into industrially important metals, and phosphoric acid and derivatives thereof. Fatty acids can be chemically transformed into useful products such as soaps, cosmetics and liquid transportation fuels such as biodiesel and conventional gasoline, diesel and aviation fuels; hydrochars created in the process can be combusted and the energy created used to generate electricity; heavy metal salts can be chemically reduced to form industrially important metals for use as catalysts; and phosphoric acid and its derivatives have very important roles as fertilizers in agriculture.
