A fluid filter has a filter housing with inlet opening for fluid to be cleaned and outlet opening for cleaned fluid. A filter element arranged in an element receptacle of the filter housing separates inlet opening from outlet opening. The filter housing has a housing body with an installation opening to the element receptacle, through which the filter element in an installation direction is introduced into the element receptacle. The filter housing has a housing cover for closing the installation opening. The installation opening is arranged in a transverse side of the housing body that is lateral relative to the housing axis. The filter housing has a sealing surface, surrounding the housing axis at least partially circumferentially, for contacting a seal of the filter element. The filter element has a seal support device for the seal and the filter housing has a pressing device for the seal support device.

A process for the production of hydrogen from an aliphatic hydrocarbon feed, uses a plasma reactor that thermodynamically breaks down the hydrocarbon into its constituent hydrogen and carbon building blocks while using the heat of the reaction product to preheat the feed high enough temperature for plasma reactor. The plasma can be energized with electrical power derived from solar, wind or hydro sources. A heat interchanger transfers the thermal energy of the reaction products to preheat the hydrocarbon feed stream thereby significantly decreasing energy needs of the process. A dual PSA system provides high hydrogen recovery at high purity. The reaction products essentially consist of hydrogen and carbon black.
