Abstract: A process for converting a biomass material comprising a) pyrolyzing a biomass material to produce a biomass-derived pyrolysis product; b) providing a petroleum-derived hydrocarbon composition having a C7-asphaltenes content of equal to or more than 0.2 wt %, based on the total weight of the petroleum-derived hydrocarbon composition, which petroleum-derived hydrocarbon composition has a total acid number of equal to or more than 0.5 mg KOH/g and/or a density at 15.5° C. of equal to or more than 0.8 grams/ml and/or a viscosity at 37.8° C. of equal to or more than 500 centiStokes (cSt); c) mixing at least part of the biomass-derived pyrolysis product and at least part of the petroleum-derived hydrocarbon composition to produce a hydrocarbon-containing mixture; and d) dewatering the hydrocarbon-containing mixture to produce a dewatered hydrocarbon-containing mixture.

Abstract: Process for the removal of cadmium from an aqueous, acidic, cadmium containing solution by electrodepositing the cadmium on conducting particulates present in a packed or fluidized bed cathode compartment of an electrolysis cell in which the aqueous, acidic, cadmium-containing solution contains phosphoric acid. The process is of particular interest for the removal of cadmium from phosphoric acid solutions which are obtained during the production of phosphorus-containing fertilizers from phosphorus rock.

Abstract: A process for the removal of arsenic compounds from tungsten and/or molybdenum concentrates by selective extraction, characterized in that the concentrates are extracted with an aqueous solution of a ferric compound of a pH below 2.5 and a temperature of at least 60.degree. C.
