An elevated target amount of electrolyte is used to initially fill a molten carbonate fuel cell that is operated under carbon capture conditions. The increased target electrolyte fill level can be achieved in part by adding additional electrolyte to the cathode collector prior to start of operation. The increased target electrolyte fill level can provide improved fuel cell performance and lifetime when operating a molten carbonate fuel cell at high current density with a low-COcontent cathode input stream and/or when operating a molten carbonate fuel cell at high COutilization.

The present disclosure relates to methods for compositional analysis of algal biomass, specifically weight percent elemental composition. In at least one embodiment, a method for compositional analysis of an algae sample includes flash combusting a first portion of the algae sample to provide a carbon wt %, a hydrogen wt %, and a nitrogen weight %. The method includes pyrolysing a second portion of the algae sample to provide an oxygen wt %. The method includes scanning a third portion of the algae sample using x-ray fluorescence to provide an elemental intensity. The method includes normalizing the elemental intensity using the carbon wt %, the hydrogen wt %, the nitrogen wt %, and/or the oxygen wt %.

Disclose is an online analyzer to monitor conversion of a biofeedstock in a first hydrotreating stage to avoid catalyst poisoning in a subsequent stage. An example method of processing a biofeedstock may comprise hydrotreating the biofeedstock by reaction with hydrogen to form a hydrotreated biofeedstock. The method may further comprise monitoring conversion of the biofeedstock in the hydrotreating with an online analyzer.
