The term HVO emerged in last decade when only vegetable oils (e.g. rapeseed, soybean and corn oil) were used as feedstocks. Today, more and more of HVO is produced from industrial waste (tall oil and fats) and used cooking oils.

WebHydrogen partial pressure (H 2 PP) plays a significant role in hydroprocessing operations. As a rule-of-thumb, catalyst deactivation rate is proportional to the reciprocal of the hydrogen partial pressure factored by an exponential ranging from 2 to 3: Catalyst deactivation rate … WebHydrogen is delivered to the MaxFlux™ reactor by recycling hydrotreated product which acts as an inert hydrogen carrier. Since there is no recycle gas, there is no need for a hot or cold high pressure separator. Only a low pressure separator is required resulting in additional cost savings.
