BASF introduces cost-effective upgrade to ozone-VOC converters for healthier aircraft cabin air; UpCore

Green Car Congress

APRIL 26, 2022

BASF has launched UpCore, a new service providing a cost-effective and sustainable technology upgrade from a standard ozone converter to an ozone-VOC (volatile organic compounds) converter for cleaner and healthier aircraft cabin air. The air at high altitude contains significant levels of ozone.

SEPTEMBER 23, 2022

The California Air Resources Board today approved a statewide plan for attaining the federal health-based standard for ozone, typically experienced as smog. The 2022 State Implementation Plan Strategy identifies the state’s control strategy for meeting the federal 70 parts per billion, 8-hour ozone standard over the next 15 years.

A fleet average nonfuel nonexhaust VOC emission factor of 58 ± 39 mg veh –1 km –1 was calculated for the missing source, which is greater than the total of all VOCs emitted from vehicle exhausts and their associated evaporative fuel losses. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). California currently limits the ethanol content of gasoline to 10 percent. The study used two fuels—an E10 and E15.

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. All totaled, engine heat accounts for 26% of the fuel consumed, and exhaust heat accounts for another 24%.
