A hydrocracking process is provided for treating a first heavy hydrocarbon feedstream and a second heavy hydrocarbon feedstream, in which the first heavy hydrocarbon feedstream contains undesired nitrogen-containing compounds, sulfur-containing compounds and poly-nuclear aromatic compounds. The attenuation stack includes a chromium layer or ruthenium layer overlying the substrate, a tantalum silicon oxide layer overlying the chromium layer or the ruthenium layer, and a tantalum silicon nitride layer overlying the tantalum silicon oxide layer. The filter container is stacked together with a cistern container and in fluid communication therebetween to form a stacked container pair as a water filter and capture module.
